LAY LANGUAGE SUMMARY OR SYNOPSIS (no more than one paragraph) 
Women with PCOS suffer from excess male hormone (androgen) production by the ovary. Androgen is made 
by cells that surround follicles that contain eggs. As the follicles (and eggs) grow and mature, there are more 
androgen producing cells. Women with PCOS have more follicles than normal women and therefore more 
androgen producing cells. While androgen production has been associated with the number of follicles, the 
relationship to the individual size of follicles in PCOS or normal women. This study intends to determine 
whether the size and number of ovarian follicles are correlated to androgen production in PCOS and normal 
women.

SPECIFIC AIMS 
Specific Aim:  To determine the relationship between ovarian follicle size and ovarian androgen production in 
women with PCOS and normal women 
Hypothesis: In PCOS excess androgen production is positively correlated to ovarian follicle size  
 
7. 
BACKGROUND AND SIGNIFICANCE 
In women with polycystic ovary syndrome (PCOS), the major abnormality is excessive ovarian androgen 
production marked by increased serum testosterone (T) and androstenedione (A) levels. Studies to determine 
the alteration in ovarian steroidogenesis that lead to abnormal production of ovarian androgens have revealed 
increased CYP17 gene expression with accentuated 17-hydroxylase activity leading to exaggerated 17-
hydroxyprogesterone (17P) responses to LH stimulation. In contrast, T and A responses did not distinguish 
between PCOS and normal women, although these androgens were clearly greater in the former compared to 
the latter group.  As a result, 17P responsiveness has been employed to determine the functional capacity of the 
ovary to produce androgen.  Stimulatory agents have included GnRH agonist, Lupron, at a dose of 10 
microgram per kilogram, or hCG at a dose of 10,000 IU.   
 
We recently showed that hCG administered intravenously in a dose-response fashion revealed gradual increases 
of 17P and a non-dose dependent increase of serum T and A. The pattern of steroid hormone production 
revealed the predominant pathway by which androgens are generated in women with PCOS. Extending these 
studies, we selected the mid-maximal dose of hCG to stimulate ovarian androgens and included morphometric 
measures of the ovary, such as ovarian follicle number (as determined by ultrasound) and related hormones, 
such as anti-mullerian hormone and inhibin B, both products of the ovarian follicle. The results showed that 
increased androgen and 17P responses in PCOS women were associated with increased antral follicle number 
and greater AMH levels compared to normal women. Inhibin B levels were similar between groups.

Based on responses observed in normal women, the PCOS women were divided into two groups. Those with 
17P responses that did not exceed the normal mean plus 2 standard deviations (normal responder PCOS; NR-
PCOS) and those that did exceed the normal response (high responder PCOS; HR-PCOS). This separation 
occurred at a rate of 50%. Notably, serum AMH levels were 2-fold higher in NR-PCOS compared to HR-
PCOS. This finding was puzzling as serum AMH levels have been shown to correlate to the number of small 
follicles present in ovaries suggesting that AMH may be a surrogate for small follicle number. However, both 
PCOS subgroups had equivalent follicle numbers. We hypothesize that the NR-PCOS have greater number of 
small follicles compared to HR-PCOS. To address this issue we propose to assess the number of small follicles 
in NR- and HR-PCOS women and normal controls.  
 
In a secondary consideration the HR-PCOS group was heavier than the NR-PCOS. This implies that the HR-
PCOS women may have had greater insulin resistance and hyperinsulinemia that may have contributed to the 
significantly higher 17P responses to hCG. As a result, we will also perform an oral glucose tolerance test in all 
subjects.  
 
Power Analysis 
Results of our pilot study have shown that approximately 50% of PCOS women will exhibit 17OHP responses 
to hCG stimulation similar to those of normal women. Consequently, a sample size of 20 subjects in each group 
has an 80% power to detect a difference in the means of 0.820 ng/ml (the difference between the average 
17OHP expression level in high responder PCOS women (HR-PCOS), 2.840 ng/ml, and that of normal 
responder PCOS (NR-PCOS) women, 2.02 ng/ml), which is a 33% increase. In the proposed study, we believe 
that HR-PCOS (n=20) will show significantly greater (33% more) 17OHP production in response to hCG 
stimulation than NR-PCOS (n=20) at a power of 0.8 and a type I error rate of 0.05. We will recruit 25 subjects 
in each group to allow for subject drop out.  A secondary analysis will be performed between women with 
PCOS and normal controls (n=20).

RESEARCH DESIGN AND METHODS 
Screening 
40 women with PCOS and 20 normal women will be studied.  Patients will be recruited from reproductive 
medicine clinics at UCSD or from the community by means of advertisement.  Subjects will have a screening 
visit to establish eligibility and to sign the informed consent.  They will have a history and physical 
examination performed which will include a urine pregnancy test, thyroid studies, a fasting chemistry panel, 
and a hemoglobin.  If the hemoglobin is less than 11 gm/dL, the subject will be given ferrous sulfate pills and 
will return at another date when her hemoglobin is above 11 gm/dL. 
 
Protocol 
1. Subjects will have a urine pregnancy test at UCSD/Reproductive Partners Medical Group.  Images of the 
both ovaries will be obtained using vaginal ultrasound and the number, size, and spatial arrangement of 
ovarian follicles will be noted for both ovaries in each subject.  The ultrasound will be completed for each 
subject according to schedule availability and each subject shall maintain normal activity before and after 
the imaging study.   
2. Normal subjects will be admitted to the CTRI during the mid follicular phase (Days 5-9) while PCOS     
      women will be anovulatory and will not have a cycle day parameter.  A urine pregnancy test will be  
      done on admission. 
3. On study day one, recombinant-hCG (r-hCG) will be administered intravenously at a dose of 25

micrograms. 
4. Blood samples will be obtained at T = -0.5, 0, and +24 hours. 
5. Blood sample will be used for DNA testing to identify genes that may be associated with androgen 
production. 
6. Sera will be assayed at all time points for steroid and peptide hormones including AMH, inhibin B, 
insulin, 17OHP, androstenedione, testosterone, dehydroepiandrosterone, estradiol, progesterone, LH, 
and FSH.  
7. One to two weeks after hCG stimulation testing each subject will come to the CTRI for an Oral Glucose 
Tolerance Test (OGTT). Each subject will ingest 75 gm of a glucose solution and blood samples will be 
obtained at 0, 15, 30, 60, 120 and 180 minutes after the glucose load.  
8. Subjects will be advised to follow a 150gram carbohydrate diet for 3 days prior to OGTT 
 
10.

RECRUITMENT AND PROCEDURES PREPARATORY TO RESEARCH 
Individuals from UCSD Reproductive Medicine Clinics, Community advertisement, or social media (Craig’s 
list, etc) will be asked whether they would be interested in participating in a research study by a reproductive 
endocrinology faculty or fellow. A brief description of the study will be made. If the patient is interested, then 
the study will be thoroughly explained to the patient by one of the investigative team members at a subsequent 
time. This will be done over the phone or by meeting with the patient in private. The patient will be given a 
consent form to take home and read. A few days later, the patient will be contacted by one of the investigative 
team members and asked if there are any questions and whether she wishes to participate. At the start of the 
study, the patient will bring a signed consent to the CTRI or sign the consent at the CTRI. This process will 
allow the patient several opportunities to withdraw if they decide not participate in the study and minimize any 
element of coercion.  
 
12. 
INFORMED CONSENT 
Participation will be completely voluntary. The purpose of the study will be thoroughly explained to all 
subjects.  The information being communicated to the participant during the consent process will include any 
exculpatory language through which the participant is made to waive or appear to waive any of the participant’s 
legal rights or release or appear to release the Researcher or the University or its agents from liability for 
negligence. A Human Subject Protection Program approved written consent and HIPAA form will be obtained 
prior to study commencement.  See attached.

14. 
POTENTIAL RISKS 
Hematological:   
Blood drawing may cause minor discomfort and potentially a slight bruise.  There is a minimal chance of 
infection.  Serum hemoglobin will be checked on all subjects prior to sampling and individuals with 
hemoglobin < 11 gm/dl will not be studied.  We estimate approximately 38 cc blood loss per patient study.  
 
Pharmacologic:   
hCG:  Ovarian theca cells are primarily stimulated by endogenous pituitary LH secretion.  The bioactive beta-
subunit of recombinant hCG is identical to LH and is used as a surrogate.  Pharmodynamic studies have shown 
that following iv administration, beta hCG rises acutely and follows a biphasic exponential disappearance curve 
similar to other gonadotropins.  Subcutaneous hCG may be associated with ovarian hyperstimulation syndrome, 
headache, confusion, dizziness, irritability, restlessness, depression, fatigue, fluid retention, breast tenderness, 
and swelling or irritation at the injection site.  IV administration has only been associated with headache and no 
immunogenicity. We have employed this drug for several years in numerous individuals and not observed any 
side effects from the drug. 
  
Transvaginal ultrasound may be associated with mild cramping or discomfort during positioning of the vaginal 
probe.   
 
15. RISK MANAGEMENT PROCEDURES AND ADEQUACY OF RESOURCES 
Qualified GCRC nurses using sterile technique will perform placement of indwelling catheters.  To assess the 
hematologic status of the subjects, we will measure hemoglobin at the beginning of the study.  A hemoglobin of 
11 gm/dL will be the minimum allowed.  If the hemoglobin is less than 11 gm/dL, subjects will be given 
ferrous gluconate pills and return at another date when their hemoglobin is above 11 gm/dL. 
 
16. PRIVACY AND CONFIDENTIALITY CONSIDERATIONS INCLUDING DATA ACCESS AND MANAGEMENT 
Each patient will be assigned a study number. None of the study documents will contain the patient’s name or 
other identifying information.  In order to protect the patient’s identity and protected information, the 
investigators will keep the list of subjects and study numbers in a locked and protected area in our research 
office. Access will be restricted to the PI.   
 
17. POTENTIAL BENEFITS 
There will be no direct benefit to the subject by participation in this study. In addition, you will not be provided 
with any results or information regarding your DNA test. However, this study may further clarify the 
mechanisms of excess androgen production in PCOS and may help us better understand the disorder. In the 
future this study may lead to improved strategies to suppress androgen production.   
18. RISK/BENEFIT RATIO 
While the control group has no direct benefit from this protocol, the information gained from their participation 
will provide important knowledge about PCOS.   Also, the dose of medication to be is minimal and we expect 
minimal if any risk to the control group. Furthermore, there is minimal risk with transvaginal ultrasound and we 
do not expect any complications with this imaging modality.  Therefore, in view of the potential reproductive 
benefits and lack of significant identified risks associated with this study, the risk/benefit ratio favors 
performing the study.  
19. EXPENSE TO PARTICIPANT
