Introduction

For many people who want to start a family, the dream of having a child is not easily realized:

about 15% of American women have received some type of infertility service. Assisted reproductive technology (ART) has been used in the United States since 1981 to help women

achieve pregnancy, most commonly through the transfer of fertilized human eggs into a

woman’s uterus. However, for many people, deciding whether to undergo this expensive and

time-consuming treatment can be difficult.

The goal of this report is to provide some of the information needed to make informed 

decisions about ART. The report addresses two questions that potential ART users frequently

ask:

• What are my chances of having a child by using ART?

• Where can I go to get this treatment?

The Society for Assisted Reproductive Technology (SART), an organization of ART providers

affiliated with the American Society for Reproductive Medicine (ASRM), has been collecting

data and publishing annual reports of pregnancy success rates for fertility clinics in the United

States and Canada since 1989. In 1992, the U.S. Congress passed the Fertility Clinic Success

Rate and Certification Act, which requires the Centers for Disease Control and Prevention (CDC)

to publish pregnancy success rates for fertility clinics in the United States.

This report of pregnancy success rates is the first to be issued under the law. It is co-authored

by CDC; SART/ASRM; and RESOLVE, a large national consumer organization that helps infertile

couples and individuals. This 1995 report is based on data annually collected by SART. A system to confirm the accuracy of the ART information reported by fertility clinics was tested on

the 1995 data and will be implemented on the 1996 data. CDC considers this first report to be

transitional. 

The 1995 ART success rate report is published in three volumes based on geographic regions.

Each volume has three parts: 

• A national report that uses information from 281 U.S. fertility clinics to provide an in-depth

national picture of ART.

• Fertility clinic reports that provide ART success rates for each clinic in the geographic region

that agreed to publish its data.

• An appendix containing a glossary of terms used in the national and clinic reports, an explanation of how the age-standardized rates were calculated, and the names and addresses of

the reporting clinics in the geographic region.

Many factors can influence a woman’s chances of having a child by using ART. The national

report presents overall success rates and shows how they are influenced by certain patient and

treatment characteristics. This information is based on cycles that started in 1995 and is organized according to the type of ART procedure used. Because the national report contains data

from 281 fertility clinics, it can give people considering ART a good idea of what the average

chances are of having a child by using this procedure. 

1
Success is also related to the expertise of a clinic’s staff and the quality of its laboratory. The

clinic reports provide results of ART procedures from the U.S. fertility clinics that agreed to

publish their data. A list of clinics that do not report their ART success rates to CDC will first be

published in the 1996 report, as required by law.

Success rates can be reported in a variety of ways, and statistics are not always simple to interpret. As a result, information about ART success rates is very complex. This report is intended

for the public and has been written so as to present the information in an easily understandable

form. A more detailed statistical analysis of the national data will be available in a subsequent

publication.

CDC, SART/ASRM, and RESOLVE hope that this report is informative and helpful to people considering an ART procedure. We welcome any suggestions for improving the report and making

it easier to use.

National

Report

1995 National Report

Data provided by U.S. clinics that use assisted reproductive technology (ART) to treat infertility

are a rich source of information about the factors that contribute to a successful ART treatment:

the delivery of a live-born infant. However, no single clinic treats a sufficient number of patients

to allow a comprehensive analysis of probable success rates. Pooling the data provides an overall national picture that could not be obtained by examining data from an individual clinic.

A variety of factors outside a clinic’s control can affect a woman’s chances of having a pregnancy and a live birth by using ART. Some of the factors covered in this report include the woman’s

age, the cause of infertility, and the number of children that the woman has already had. Other

factors for which data were not available may also be important; examples include the length of

time that infertility has been a problem and the number of previous unsuccessful ART attempts.

The national data are useful because they can give potential ART users an idea of their average

chances of success. Average chances, however, do not necessarily apply to a particular individual or couple. People considering ART should consult their physician to discuss all the factors

that apply in their particular case.

The data for this national report come from the 281 fertility clinics that provided information

about the outcomes of all ART cycles started in their clinics in 1995. All of these clinics are

members of the Society for Assisted Reproductive Technology (SART). Although we believe that

these 281 clinics represent almost all clinics in the United States that use ART, data for some

clinics or practitioners may not have been included in this report. We will make every effort to

provide a list of all clinics and practitioners providing ART services in future reports. 

The national report consists of figures (graphs and charts), based on 1995 data, that answer

specific questions related to ART procedures. These figures are organized according to the type

of ART procedure used. Some ART procedures use a couple’s own gametes (nondonor eggs

and sperm), and others use eggs donated by another woman (donor eggs). In some procedures, the embryos that develop are transferred back to the woman within a day or two of fertilization (fresh transfer); in others, the embryos are frozen (cryopreserved) for transfer at a later

date.

• Section 1 (Figures 1 and 2) presents information from all ART procedures reported.

• Section 2 (Figures 3 through 14) presents information on the 45,906 ART cycles that used

only fresh embryos from nondonor eggs or, in a few cases, a mixture of fresh and frozen

embryos from nondonor eggs. 

• Sections 3 and 4 (Figures 15 through 17) present information on the 13,236 ART cycles that

used only frozen embryos or donated eggs.

Technical terms are defined in the glossary in the appendix.

5
What type of ART procedure is most often used?

In 1995, 59,142 ART cycles were carried out in the United States. As Figure 1 shows, most of

these cycles (78%) used fresh embryos developed from a couple’s own egg and sperm and one

of the following ART procedures:

• IVF (in vitro fertilization), used in 70% of procedures in 1995, involves extracting a

woman’s eggs, fertilizing the eggs in the laboratory, and then transferring the resulting

embryo(s) into the woman’s uterus through the cervix. Approximately 11% of the ART procedures carried out in 1995 also included intracytoplasmic sperm injection (ICSI). This procedure, which involves injecting a sperm directly into an egg, is most often used in cases of

male infertility.

• GIFT (gamete intrafallopian transfer) was used in 6% of procedures. In GIFT, a fiber-optic

instrument called a laparoscope is used to place the unfertilized eggs and sperm (gametes)

into the woman’s fallopian tubes through a small incision in her abdomen. 

• ZIFT (zygote intrafallopian transfer), used in only 2% of procedures in 1995, involves fertilizing a woman’s eggs outside her body and then using a laparoscope to transfer the fertilized eggs (zygotes) into her fallopian tubes. 

Fourteen percent of all ART cycles used frozen embryos from nondonated eggs that had been

thawed and then transferred into the woman’s uterus, and 8% used donated eggs.

SECTION 1: OVERVIEW
Where are ART clinics located?

Although ART clinics are spread throughout the United States, the greatest number of clinics is

in the East. Most clinics are in or near major cities. Figure 2 shows the location of the 281

reporting clinics; the larger the dot marking the location, the more clinics in that area. The bold

lines indicate regional divisions that correspond to the three volumes of this report: Volume 1—

Eastern United States, Volume 2—Central United States, and Volume 3—Western United States.

SECTION 2: ART CYCLES USING FRESH,* 

NONDONOR EGGS OR EMBRYOS

Figure 3 shows ART cycles in 1995 according to the age of the woman who had the procedure.

For example, 8% of the 45,906 ART cycles carried out that year using fresh nondonor eggs or

embryos were in women 34 years old. Very few women under age 25 used ART. Most ART

cycles carried out in 1995 (77%) were in women between 30 and 40 years old. Very few

women older than age 45 used ART with their own eggs.

*Fresh, nondonor cycles included some cycles with a mixture of fresh and frozen nondonor

eggs or embryos.

Figure 4 shows the number of previous children born to women who had an ART procedure in

1995. Most of these women (77%) had no previous births; however, they may have had a

pregnancy that resulted in a miscarriage or a therapeutic abortion. A small percentage (17%)

reported one previous birth, and 6% reported two or more. However, we do not know how

many of these children were conceived naturally and how many by an ART procedure. These

data nonetheless point out that infertility can occur among couples who have had children.

Figure 5 shows the primary diagnoses responsible for infertility among couples who had an ART

procedure in 1995. However, some couples have more than one cause of infertility.

• Tubal factor usually means that the woman’s fallopian tubes are blocked or damaged, making it difficult for the egg to be fertilized or for an embryo to travel to the uterus.

• Male factor usually refers to a low sperm count or problems with sperm function or motility

(ability to move) that make it difficult for a sperm to fertilize an egg under normal conditions. 

• Endometriosis involves the presence of tissue similar to the uterine lining in abnormal locations. This condition can affect both fertilization of the egg and implantation of the embryo in

the uterus.

• Ovarian factor means that the ovaries are not producing eggs normally.

• Other causes of infertility include problems with the uterus, such as abnormal shape or

fibroid tumors, and exposure to diethylstilbestrol (DES) as a fetus. (In the 1950s and 1960s,

DES was given to some women to prevent miscarriages.)

• Unexplained cause of infertility means that, despite numerous tests, no cause of infertility

could be found in either the woman or the man.

Several measures can be used to assess ART success rates. Each provides slightly different

information about this complex process. Figure 6 shows ART success rates using four different

ways of measuring ART success:

• The live birth per cycle rate (LB/cycle), commonly called the “take-home baby rate,” shows

the percentage of cycles started that resulted in a live birth. This rate is the one most people

are interested in when considering ART. In all of the graphs and charts in this report, live

birth rate means live birth per cycle rate unless otherwise specified. 

• The pregnancy per cycle rate (Preg/cycle) refers to a clinical pregnancy (defined as the presence of a gestational sac on ultrasound) resulting from one full treatment, or cycle, of ART.

This rate is always higher than the live birth per cycle rate because some pregnancies are lost

through miscarriage or therapeutic abortion and a small percentage end in a stillbirth.

• The live birth per egg retrieval rate (LB/retr) is generally higher than the live birth per cycle

rate because it excludes those cycles that are canceled. In 1995, approximately 14% of all

ART cycles were canceled and no eggs were retrieved, most commonly because too few follicles (eggs) developed. Illness unrelated to the ART procedure may also lead to cancellation.

• The live birth per embryo transfer rate (LB/trans) includes only those cycles in which an

embryo or egg and sperm were transferred back to the woman. It excludes cycles in which

no transfer occurred because the egg was not fertilized or the embryos formed were abnormal. As a result, it is generally higher than the live birth per egg retrieval rate.

Live birth rates vary by type of ART procedure used. Figure 7 shows the percentage of egg

retrievals in 1995 that used a particular type of ART procedure and resulted in a live birth. IVF

appears to have a lower success rate than GIFT or ZIFT. However, these rates do not take into

account patient and diagnostic factors that may account for the differences in success; these factors include patient age, diagnosis, length of infertility, and number of previous ART attempts.

Many women are not suitable candidates for GIFT and ZIFT. It should also be noted that GIFT

and ZIFT are more invasive procedures than IVF because they involve inserting a laparoscope

into a woman’s abdomen to transfer the embryos or oocytes into the fallopian tubes. In contrast, IVF involves simply transferring embryos into a woman’s uterus through the cervix without

surgery. 

Figures 8 through 14 present IVF, GIFT, and ZIFT results together because the numbers of ZIFT

and GIFT procedures are relatively small.

Figure 8a shows the results of ART cycles performed in 1995. Most of these cycles (76%) did

not produce a clinical pregnancy. The 24% of cycles that resulted in a clinical pregnancy included the 5% of all cycles that had an adverse outcome (ectopic pregnancy, spontaneous abortion

[miscarriage], induced abortion, or stillbirth), the 12% that produced a single live birth, and the

7% that resulted in a multiple birth. See Figure 8b for more detailed information on ART clinical

pregnancy outcomes.

Figure 8b shows the outcomes of the 24% of ART cycles (the pie slice on Figure 8a) that resulted in a clinical pregnancy. Of all these pregnancies, 22% resulted in an adverse outcome and

78% resulted in a live birth. Adverse pregnancy outcomes included spontaneous abortions

(17.0%), ectopic (tubal) pregnancies (2.7%), induced abortions (1.5%), and stillbirths (0.7%).

Approximately 50% of pregnancies resulted in a single birth and 28% in a multiple birth. Thus,

37% of all ART births were multiple births, compared with 2% of births in the general population. Multiple births are associated with greater problems, including medical complications and

higher caesarean-section rates among mothers and prematurity, low birth weight, and developmental disabilities among infants.

A woman’s age is the most important factor affecting the chances of a live birth when the

woman’s own eggs are used. Figure 9 shows the live birth rate for women of a given age who

had an ART procedure in 1995. Rates were relatively constant at about 25% among women

aged 34 years and younger but declined with age after 34. Success rates were zero among

women aged 47 years and older.

Figure 10 shows the relationship between the success of an ART cycle performed in 1995 and

the number of previous births to the woman who had the treatment. Women of all age groups

who had had a previous live birth were more likely to have a live birth by using ART. Previous

children were conceived naturally in some cases and through ART in others.

Are women who have previously given 

birth more likely to have success using ART?

Figure 12 shows the relationship between the number of embryos transferred during an ART

procedure in 1995 and the number of infants born alive as a result of that procedure. As

women get older, success rates decrease and the number of embryos transferred increases. To

show more clearly the relationship between success rates and numbers of embryos transferred,

Figure 12 presents results only for women younger than age 35. However, the trends are the

same for all age groups. In 1995, the chance of both a live birth and a multiple birth increased

with each embryo transferred up to four. Beyond five embryos, the live birth rate changed very

little, but the multiple birth rate continued to increase.

Is an ART cycle more likely to be successful 

when more embryos are transferred?

In 1995, approximately 11% of ART procedures used ICSI (intracytoplasmic sperm injection, a

procedure in which a single sperm is injected directly into an egg), most often to overcome

problems with sperm function or motility. Figure 13 shows the success rates for ART procedures involving ICSI compared with those not involving ICSI for couples with male factor as 

the primary diagnosis. Because ICSI can be performed only when at least one egg has been

retrieved, only the live birth per retrieval (LB/retr) rate and the live birth per transfer (LB/trans)

rate are compared. In 1995, success rates were higher among couples with male factor infertility when ICSI was used.

Is an ART cycle more likely to be successful for 

couples with male factor infertility when ICSI is used?

Fertility clinics in the United States vary in the number of ART procedures that they carry out

every year. In Figure 14, clinics are divided into four equal groups based on the number of

cycles they carried out in 1995. This chart shows that a clinic’s success rate is not related to the

number of procedures it carries out annually. Very small and very large clinics had nearly the

same results. 

Does the size of the clinic affect its success rate?

SECTION 3: ART CYCLES USING 

ONLY FROZEN EMBRYOS

Approximately 14% of all ART cycles performed in 1995, or 8,453 cycles, used only frozen

embryos. Figure 15 compares the success rates for frozen embryos with the rate for fresh

embryos. Some embryos do not survive the freezing or thawing process. Thus, the live birth per

thaw rate, which takes into account all embryos frozen, is usually lower than the live birth per

transfer rate. In 1995, the live birth per thaw and live birth per transfer rates for frozen embryos

were lower than the live birth per transfer rate for fresh embryos. However, on average, fewer

embryos are transferred in frozen cycles than in fresh cycles, and this may partly explain the

lower success rates. (See the 1995 National Summary on page 35.) Cycles that use frozen

embryos can be considered a “bonus” because the woman does not have to go through the

stimulation and retrieval process again. The cost of a frozen cycle is thus lower than the cost of

a fresh cycle.

What are the success rates 

for ART using frozen embryos?

SECTION 4: ART CYCLES USING DONOR EGGS

As women age, the eggs they produce form embryos that are less likely to implant and more

likely to miscarry if they do implant. As a result, ART using donor eggs is much more common

among older women than among younger women. Donor eggs were used in approximately

8% of all ART cycles carried out in 1995, or 4,783 cycles. Of these cycles, 78% used fresh

embryos formed from donor eggs, and 22% used frozen embryos. Figure 16 shows the percentage of ART cycles using donor eggs in 1995 according to the woman’s age. Donor eggs

were used in only a small percentage of cycles among women younger than age 37. The percentage of cycles carried out with donor eggs then increased sharply. More than 70% of all ART

cycles carried out among women older than age 46 used donor eggs. 

Are older women more likely 

to have ART using donor eggs?

Donor Egg Cycles

Figure 17 shows that the age of the woman undergoing ART treatment does not affect success

rates for cycles using embryos formed from donor eggs as it affects success rates for cycles

using embryos from a woman’s own eggs. The likelihood of a fertilized egg implanting is related to the age of the woman who produced the egg. As a result, the success rate for cycles

using donor embryos is nearly constant (around 30%) across all age groups from 22 to 50. This

graph illustrates that women age 36 and older are more likely to have success with ART using

donor eggs.

Many factors contribute to the success of an ART procedure. Some of these factors are related

to the patients themselves, such as their age and the cause of their infertility. Others, however,

are related to the training and experience of ART clinic and laboratory professionals and the

quality of services they provide. Many people considering ART will want to use this report to

find the “best” clinic. However, comparisons between clinics must be made with caution. Clinics

may specialize in different ART treatments or attract a particular type of patient. These and

other reasons why comparing clinics with each other or with national data can be misleading

are discussed below. 

Important Factors to Consider 

When Using These Reports to Assess a Clinic

• These statistics are for 1995. Data for cycles started in 1995 were not published until 1997

because the final outcomes of pregnancies conceived in December 1995 were not known

until October 1996. Additional time was then required to collect and analyze the data. Many

factors that contribute to a clinic’s success rate may have changed, for better or for worse, in

the 2 years since these procedures were performed. Personnel may be different. Equipment

and training may or may not have been updated. As a result, success rates for 1995 may not

reflect those for 1997 or 1998. 

• No reported success rate is absolute. Every success rate has a margin of error, or range within which it is likely to be correct. Therefore, a clinic’s success rates will vary from year to year

even if all determining factors remain the same. The larger the number of cycles that a clinic

carries out, the less the rate is likely to vary. Conversely, the smaller the number of cycles,

the greater the margin of error and the more variability in success rates from year to year. 

As an extreme example, if only one case is reported in a given category (which occurs many

times in the data presented here), the clinic’s success rate in that category would be either

0% or 100%. Thus, rates derived from a small number of cases are almost certain to vary

considerably from year to year. For further detail, see the explanation of confidence interval

on page 32.

• Some clinics see more than the average number of patients with difficult infertility problems.

Some clinics are willing to offer ART to most potential users, even those who have a low

probability of success (known as “poor responders”). Others discourage such patients or

encourage them to use donor eggs, which have higher success rates among women older

than 35. Some clinics have an age cut-off for nondonor ART. Clinics that accept a higher percentage of women with multiple previous unsuccessful attempts will generally have lower

success rates than clinics that do not. Alternatively, some clinics may raise their success rates

by offering ART procedures to patients who might have become pregnant with less technologically advanced treatment. 

• Success rates for unstimulated (or “natural”) cycles are included with those for stimulated

cycles. In an unstimulated cycle, the woman ovulates naturally rather than through the daily

injections required by stimulated cycles. Nationally, about 1% of ART users choose to do

unstimulated cycles. However, in some clinics, up to 15% of women have unstimulated

cycles. Unstimulated cycles are less expensive because they eliminate the cost of the

Introduction to Fertility Clinic Reports
28

injectable drugs. They further reduce the cost of the procedure by reducing the number of

ultrasounds and blood tests required. However, women who use natural or mild stimulation

produce only one or two follicles, thus reducing the potential number of embryos for transfer.

As a result, unstimulated cycles have lower success rates, and clinics that carry out a relatively

high proportion of unstimulated cycles will have lower success rates than those that do not. 

• Success rates for GIFT and ZIFT are reported together with those for IVF. Because success

rates for GIFT and ZIFT are higher than rates for IVF, clinics that do more GIFT and ZIFT procedures will have higher success rates. However, many women are not suitable candidates for

GIFT or ZIFT. As mentioned on page 10, GIFT and ZIFT are more invasive than IVF, and many

clinics now perform very few GIFT and ZIFT procedures.

• Cycles in which all embryos were frozen for transfer at a later date are counted as failures in

the fresh, nondonor category. Clinics that have a high proportion of procedures in which all

embryos are frozen will have low success rates for ART procedures using fresh embryos,

even if their success rates for frozen embryos are very good.

• Cycles with extra embryos that were frozen and transferred at a later date and which then

resulted in a live birth are counted only under frozen cycles. Clinics that have very good live

birth rates with frozen embryos would have higher ART success rates if live births from

frozen embryos were included as a success for the original stimulated cycle. Consumers

should look at rates for both fresh and frozen cycles when assessing a clinic’s success rates. 

• The number of embryos transferred varies from clinic to clinic. In 1995, the average number

of embryos that a clinic transferred to women younger than 35 years old varied between 1.7

and 7.3. The American Society for Reproductive Medicine discourages the transfer of a large

number of embryos because it increases the likelihood of multiple births. Multiple births, in

turn, increase the likelihood of elected multifetal pregnancy reductions as well as the probability of premature birth and its related problems. 

• Cancellation rates affect a clinic’s success rate. Some clinics are more likely than others to

cancel a cycle if a woman produces only a small number of follicles. Cancellation rates vary

among clinics from zero to more than 40%. A high cancellation rate tends to lower the live

birth per cycle rate but increase the live birth per retrieval and live birth per transfer rates. 

In addition, success rates can be affected by many factors, including

• The quality of eggs (largely related to the woman’s age).

• The quality of sperm (including motility and ability to penetrate the egg).

• The skill and competence of the treatment team.

• The general health of the woman.

• Genetic factors.

We encourage consumers considering ART to contact clinics to discuss their specific medical situation and their potential for success using ART. Because clinics did not have the opportunity to

provide a narrative to explain their data, such a conversation could provide additional information to help people decide whether or not to use ART. 
29

Although ART offers important options for the treatment of infertility, the decision to use ART

involves many factors in addition to success rates. Going through repeated ART cycles requires

substantial commitments of time, effort, money, and emotional energy. Therefore, consumers

should carefully examine all related financial, psychological, and medical issues before beginning treatment. They will also want to consider the location of the clinic, the counseling and

support services available, and the rapport that staff have with their patients. 

An explanation of how to read a fertility clinic report begins on page 31. A summary of national

data from the 281 reporting clinics appears on page 35, followed by data from individual fertility clinics listed in alphabetical order by state and city. 

Although data from 281 clinics are included in the national report, the three volumes of this

1995 report together contain only 259 individual clinic reports for several reasons. First, CDC

will not publish data for a clinic if the program director does not personally verify the data; such

verification was provided by 268 of the 281 reporting clinics. Second, clinics are not required to

publish their data unless they have been in operation for a full year; one clinic elected not to

publish its data for this reason. Third, of the remaining 267 clinics, eight requested that their

data for 1995 not be published; many of these clinics had carried out a large number of unstimulated cycles or cycles in which all embryos were frozen, thus lowering their success rates.

Because of the much lower success rates for such cycles, in future reports they will not be

reported together with cycles using fresh embryos from nondonor eggs.

How to Read a Fertility Clinic Report

This section is provided to help consumers understand the information presented in the fertility

clinic reports. The number before each heading refers to the number of the corresponding section in the sample clinic report on the opposite page. Technical terms are defined in the glossary in the appendix.

1. Program Characteristics

• SART member—All clinics reporting data from 1995 are SART members, but this annual

report will eventually include information from all U.S. fertility clinics, not just those that are

SART members. 

• Single women and surrogates—Clinics have varying policies regarding ART services for single women and surrogates (women who carry a child for another woman). 

• Donor eggs shared—The percentage of donor eggs shared refers to the percentage of

donor cycles in which eggs from a single donor were given to more than one woman. This

rate varies from clinic to clinic and is one that many women ask about when considering

using donor eggs. 

2. Type of ART Used

In the fertility clinic reports, ART success rates are not broken down into IVF, GIFT, and ZIFT. (See

glossary for definitions.) Because the percentages of GIFT and ZIFT are usually small, these three

types of ART are combined. However, knowing the percentage of each type of procedure performed can be useful because carrying out a higher percentage of GIFT and ZIFT procedures may

increase a clinic’s success rate. This section also indicates the percentage of procedures that

involved intracytoplasmic sperm injection (ICSI), which was not performed at all clinics in 1995. 

3. ART Patient Diagnosis

Consumers may want to know what percentage of a particular clinic’s patients have the same

diagnosis as they do. In addition, patients’ diagnoses can affect a clinic’s success rates. (See the

glossary for definitions of diagnoses.)

4. Age of Woman 

Because a woman’s fertility declines with age, clinics report lower success rates for older women

attempting to become pregnant with their own eggs. For this reason, rates are reported separately for women younger than 35, for women between the ages of 35 and 39, and for women

older than 39 years of age. The sample clinic profile illustrates the decline in ART success rates

among older women: 27.3% of cycles started at this clinic among women younger than 35 years

of age resulted in a live birth, whereas only 7.0% of cycles started among women older than 39

resulted in a live birth. 

5. Age-Standardized Rate

The national report shows how much success rates for ART using nondonor eggs depend on a

woman’s age: women younger than 35 are much more likely to have success with ART. As a

result, for a clinic’s overall success rates to be meaningful, we must account for the ages of the
women it treats. Age standardization adjusts for differences among clinics in the ages of the

women they treat by calculating the rate each clinic would have if all clinics treated the same

percentage of women in each of the age groups. A statistical explanation of how these rates

were calculated is provided in the appendix. 

Age-standardized rates are provided only for fresh, nondonor cycles because most clinics carried out too few cycles with frozen embryos and donor eggs for reliable age-standardized rates

to be calculated. Age-standardized rates are not provided if the total number of cycles is fewer

than 20 or if there are fewer than 5 cycles in any one of the age groups.

6. 95% Confidence Interval

The 95% confidence interval is a statistical term. When used with ART success rates, it indicates

that if a clinic performed the same procedure on the same number of patients 100 times, the

success rate for 95 of these procedures would fall within the range shown. As noted in the second bullet on page 27, the size of this range or confidence interval depends on the number of

procedures a clinic has carried out. Using the age-standardized rates of the sample clinic as an

example, we are 95% confident that the success rate is somewhere between 21.1% and 28.4%

when calculated as pregnancies per cycle.

The 95% confidence interval can be an important factor to consider when comparing clinics in

which all factors except the number of procedures are equal. For example, if Clinic A has a 20%

success rate and Clinic B has a 25% success rate, we might be tempted to say that Clinic B has

a better rate. However, if the 95% confidence interval is 14%–26% for Clinic A and 21%–29% 

for Clinic B, then their confidence intervals overlap and the difference between their success

rates is not meaningful. 

7. Cycles Using Fresh Embryos From Nondonor Eggs

All success rates are calculated as either the number of pregnancies or the number of pregnancies resulting in a live birth divided by the number of cycles started, egg retrievals, or embryo

transfers. Multiple births are counted as one “live birth.” This section includes IVF, GIFT, and ZIFT

cycles that used a woman’s own eggs. Cycles that used frozen embryos or donor eggs are not

included here.

• Percentage of Pregnancies Per Cycle Started

(Number of pregnancies divided by the number of cycles started)

This number represents the number of clinical pregnancies from ART as a percentage of all

cycles that were started at the clinic during the reporting period. A cycle is “started” when a

woman begins taking fertility drugs or being monitored. The number of cycles that a clinic

starts is not the same as the number of patients that it treats because some women start

more than one cycle in a year. A clinical pregnancy is defined as the presence of a gestational sac on ultrasound. However, some pregnancies end in a spontaneous abortion (miscarriage) or a stillbirth. Because not all clinical pregnancies result in a live birth, this rate is 

usually higher than the live birth rate. 

• Percentage of Live Births Per Cycle Started

(Number of pregnancies resulting in a live birth divided by the number of cycles started)

This number represents the percentage of cycles that resulted in a live birth out of all ART

32
cycles started. Often called the “take-home baby rate,” this is the rate that most people are

interested in when deciding whether or not to use ART.

• Percentage of Live Births Per Egg Retrieval

(Number of pregnancies resulting in a live birth divided by number of egg retrievals)

This number represents the percentage of cycles that resulted in a live birth out of all cycles in

which an egg retrieval was performed. The number of egg retrievals a clinic performs is often

smaller than the number of cycles started because some cycles are canceled before the woman

has an egg retrieved. As a result, this rate is usually higher than the live births per cycle started

rate. 

• Percentage of Live Births Per Embryo Transfer

(Number of live births divided by number of embryo transfers)

This number represents the percentage of cycles that resulted in a live birth out of all cycles in

which one or more embryos were transferred into the woman’s womb, or in the case of GIFT

and ZIFT, egg and sperm or embryos were transferred into the woman’s fallopian tubes. The

number of embryo transfers a clinic carries out may be smaller than its number of egg

retrievals because not every retrieval results in egg fertilization and embryo transfer. For this

reason, live birth rates based on transfers will be higher than those reported for egg retrievals

and for cycles started.

• Cancellations refer to the percentage of all cycles that are stopped before an egg is

retrieved. A cycle may be canceled if a woman’s ovaries do not respond to fertility medications and thus produce an insufficient number of follicles. Cycles are also canceled because of

illness.

8. Cycles Using Frozen Embryos From Nondonor Eggs

Frozen (cryopreserved) cycles are those in which previously frozen embryos are thawed and

then transferred. Because cryopreserved cycles use embryos formed from a previous stimulated

cycle, no stimulation or retrieval is involved. As a result, these cycles are usually less expensive

than cycles using “fresh” embryos. In addition, high frozen embryo success rates increase a

woman’s overall chances of having a child. 

9. Cycles Using Donor Eggs

Older women, women with premature ovarian failure (early menopause), and women with a

genetic concern about using their own eggs may consider using eggs that are donated by a

young and healthy woman. Many clinics provide services for donor egg cycles. Note that live

birth rates do not vary much by age when donor eggs are used. (See Figure 17.)

10. Use of Fractions Rather Than Percentages in Tables

Fractions are used when fewer than 20 cycles are reported in a given category. Percentages are

not meaningful with such small numbers because the margin of error is too large. For example,

the sample clinic carried out only five cycles using donor eggs among women younger than

age 35. Of these five cycles, three, or 60%, were successful. However, because of the small

number of cycles, the 60% is not a reliable success rate. (For further explanation, see the second

bullet on page 27.)

American Society for Reproductive Medicine

(ASRM)—Professional society whose affiliate organization, the Society for Assisted Reproductive Technology (SART), reports annual fertility clinic data to

the Centers for Disease Control and Prevention

(CDC).

ART (assisted reproductive technology)—All treatments or procedures that involve the handling of

human eggs and sperm for the purpose of establishing a pregnancy. Types of ART include IVF, GIFT, ZIFT,

embryo cryopreservation, egg or embryo donation,

and surrogate birth.

ART cycle—A process in which (1) an ART procedure is carried out, (2) a woman has undergone

ovarian stimulation or monitoring with the intent of

having an ART procedure, or (3) in the case of frozen

embryos, embryos have been thawed with the intent

of transferring them to a woman. A cycle starts when

a woman begins taking fertility drugs or starts ovarian monitoring.

Canceled cycle—An ART cycle that is stopped after

ovarian stimulation has been carried out but before

eggs are retrieved or, in the case of frozen embryo

cycles, before embryos are transferred. 

Cryopreservation—A technique for preserving tissue

through freezing that is used to preserve embryos for

transfer at a later date. In this report, cryopreserved

embryos are referred to as frozen embryos. 

Donor embryo—An embryo formed from the egg of

a woman who has donated it for transfer to a woman

who is unable to conceive with her own eggs (the

recipient). The donor relinquishes all parental rights

to any resulting offspring. 

Ectopic pregnancy—A pregnancy in which the fertilized egg implants in a location outside the uterus—

usually in the fallopian tube, the ovary, or the

abdominal cavity. Ectopic pregnancy is a dangerous

condition that must receive prompt treatment. 

Egg—A female reproductive cell, also called an

oocyte or ovum. 

Egg retrieval (also called oocyte retrieval)—A procedure to collect the eggs contained in the ovarian

follicles. 

Egg transfer (also called oocyte transfer)—The

transfer of retrieved eggs into a woman’s fallopian

tubes through laparoscopy. This procedure is used

only in GIFT (see definition).

Embryo—An egg that has been fertilized by a sperm

and that has undergone one or more divisions. 

Embryo transfer—Placement of embryos into a

woman’s uterus through the cervix after IVF (see definition) or, in the case of ZIFT (see definition), into her

fallopian tubes.

Endometriosis—The presence of tissue similar to the

uterine lining in locations outside the uterus, such as

the ovaries, fallopian tubes, and abdominal cavity.

Fertilization—The penetration of the egg by the

sperm and the resulting fusion of genetic material

that develops into an embryo.

Follicle—A structure in the ovaries that contains a

developing egg.

Fresh eggs, sperm, or embryos—Eggs, sperm, or

embryos that have not been frozen. However, fresh

embryos may have been conceived using either fresh

or frozen sperm.

Gamete—A reproductive cell, either a sperm or an

egg.

Gestational sac—A fluid-filled structure that develops within the uterus early in pregnancy.

GIFT (gamete intrafallopian transfer)—An ART 

procedure that involves removing eggs from the

woman’s ovary, combining them with sperm, and

using a laparoscope to place the unfertilized eggs

and the sperm into the woman’s fallopian tubes

through a small incision in her abdomen. 

Induced or therapeutic abortion—An operative

procedure used to end a pregnancy.

ICSI (intracytoplasmic sperm injection)—A procedure in which a single sperm is injected directly into

an egg; this procedure is most commonly used to

overcome male infertility problems. 

IVF (in vitro fertilization)—An ART procedure that

involves removing eggs from a woman’s ovaries 

Glossary of ART Terminology

and fertilizing them in the laboratory. The resulting

embryos are then transferred into the woman’s

uterus through the cervix. 

Laparoscopy—A surgical procedure in which a fiberoptic instrument (a laparoscope) is inserted into the

pelvic area through a small incision in the abdomen.

Live birth—Any infant delivered with signs of life

after 20 or more weeks of gestation.

Male factor—Deficiencies in sperm quantity, function, or motility (ability to move) that make it difficult

for a sperm to fertilize an egg under normal conditions. 

Multifetal pregnancy reduction—A procedure in

which the number of gestational sacs is reduced. This

procedure is used to decrease the number of fetuses

a woman carries and thereby improve the chances

that the remaining fetuses will survive and develop

into healthy infants. 

Multiple birth—A pregnancy that results in the birth

of more than one infant. 

Oocyte—The female reproductive cell, also called an

egg or ovum.

Ovarian factor—A cause of infertility related to

problems with egg production by the ovaries. 

Ovarian monitoring—The use of ultrasound and/or

blood or urine tests to monitor the development of

ovarian follicles.

Ovarian stimulation—The use of drugs to stimulate

the ovaries to develop follicles and eggs.

Pregnancy, Chemical—Pregnancy documented by a

blood or urine test that shows a rise in the level of

the human chorionic gonadotropin (hCG) hormone.

Pregnancy, Clinical—Pregnancy documented by the

presence of a gestational sac on ultrasound.

Pregnancy test—A blood or urine test that determines the level of the human chorionic gonadotropin

(hCG) hormone. Elevated levels of this hormone are

chemical evidence of a pregnancy. 

RESOLVE—A national, nonprofit consumer organization offering education, advocacy, and support to

persons experiencing infertility. Services include a

national HelpLine, quarterly newsletter, extensive 

literature list, member-to-member nationwide contact systems, and local support groups through a

network of more than 50 chapters.

SART (Society for Assisted Reproductive

Technology)—An affiliate of the American Society 

for Reproductive Medicine composed of clinics and 

programs that provide ART. SART reports annual 

fertility clinic data to the Centers for Disease Control

and Prevention (CDC).

Sperm—The male reproductive cell.

Spontaneous abortion (miscarriage)—A pregnancy

ending in the spontaneous loss of the embryo or

fetus before 20 weeks of gestation.

Stillbirth—An infant delivered without signs of life

after 20 or more weeks of gestation.

Stimulated cycle—An ART cycle in which a woman

receives drugs to stimulate her ovaries to produce

more follicles. 

Surrogate—A woman who carries an embryo that

was formed from the egg of another woman; the

surrogate is expected to return the infant to its

genetic parents.

Thawed cycle—A cycle in which previously frozen

embryos are thawed for embryo transfer.

Tubal factor—A cause of infertility related to structural or functional damage to one or both fallopian

tubes.

Ultrasound—A noninvasive technique for visualizing

the follicles in the ovaries and the gestational sac or

fetus in the uterus.

Unexplained cause of infertility—Infertility for

which no cause has been determined despite a comprehensive evaluation.

Unstimulated cycle—An ART cycle in which the

woman does not receive drugs to stimulate her

ovaries to produce more follicles. Instead, follicles

develop naturally. 

Uterine factor—A cause of infertility related to

defects in the uterus.
111

ZIFT (zygote intrafallopian transfer)—An ART procedure in which eggs are collected from a woman’s

ovary and fertilized in the laboratory. A laparoscope

is then used to place the resulting zygote (fertilized

egg) into the woman’s fallopian tubes through a

small incision in her abdomen.

In the 1995 annual report, we obtained an age-standardized live birth rate and its associated

95% confidence interval by following the calculations for steps 1–4. We assumed that each clinic treated the same proportion of women in each of the age groups. The proportions used were

based on the pooled national age distribution for all women who had an ART procedure in

1995: 46% were younger than 35 (x = 46), 36% were between 35 and 39 (y = 36), and 18%

were older than 39 (z = 18).

Step 1: Calculation of age-standardized live birth rate

x% x (clinic’s live birth rate among women younger than 35) + 

y% x (clinic’s live birth rate among women between 35 and 39) +

z% x (clinic’s live birth rate among women older than 39).

Step 2: Calculation of variance for age-standardized live birth rate

(x%)

2 x var(1) + (y%)2 x var(2) + (z%)2 x var(3),

where var(1) is calculated as [live birth rate x (100 – live birth rate)] ÷ (number of women

younger than age 35), the variance of the live birth rate among women younger than 35, and

var(2) and var(3), for age groups 35 to 39 and older than 39, respectively, are calculated using

the same procedure as for var(1). 

Step 3: Calculation of lower bound of 95% confidence interval

(age-standardized rate from step 1) – 1.96 x square root(variance from step 2), 

which is equal to zero if the calculated value is less than zero.

Step 4: Calculation of upper bound of 95% confidence interval

(age-standardized rate from step 1) + 1.96 x square root(variance from step 2), 

which is equal to 100 if the calculated value is greater than 100.
