INTRODUCTION  
 
1.1 
BACKGROUND 
Infertility is commonly defined as the inability to conceive after two years of regular unprotected sexual 
intercourse (1). Infertility has a high prevalence; it is estimated that around one in six UK couples have 
difficulty conceiving i.e. approximately 3.5 million couples (1). The inability to have children can be 
devastating, and has important implications for mental, social, and reproductive health.  
 
In healthy women, the reproductive cycle is controlled by the hypothalamic-pituitary gonadal (HPG) axis. 
GnRH released from the hypothalamus stimulates the release of the gonadotrophins, luteinising 
hormone (LH) and FSH from the anterior pituitary gland. These gonadotrophins in turn regulate ovarian 
function and oocyte maturation and ovulation which are driven by an LH surge. Recently kisspeptin has 
been shown to be responsible for the endogenous LH surge, via the stimulation of hypothalamic GnRH 
release (6). After ovulation, progesterone produced by the corpus luteum prepares the endometrium for 
embryo implantation. Normal function of the corpus luteum is dependent on the pituitary secretion of 
LH. IVF treatment uses the exogenous administration of hormones to stimulate ovarian follicular 
development and oocyte maturation. FSH injections are used to stimulate ovarian follicular development 
and endogenous LH production is blocked in order to prevent premature ovulation. Once 3 dominant 
follicles have developed, hCG is administered to stimulate oocyte maturation. The oocytes are collected 
and fertilised with sperm in vitro. The embryo is then replaced into the endometrial cavity to allow 
implantation and pregnancy to occur.  
 
IVF treatment is widely and successfully used to allow infertile couples to conceive and is now approved 
by the National Institute for Health and Clinical Excellence (NICE). However, the most common serious 
complication of IVF is ovarian hyperstimulation syndrome (OHSS), a potentially life threatening condition 
which has significant morbidity and mortality (2). OHSS is a systemic disease resulting from the release 
of vasoactive products from hyper stimulated ovaries. This potentially life threatening condition can 
cause massive ovarian enlargement, ovarian torsion, ascites, hydrothorax, liver dysfunction, 
thromboembolism, electrolyte imbalance, renal failure and acute respiratory distress syndrome (ARDS) 
and death (2). Mild forms of OHSS are common, occurring in 1 in 3 of all IVF cycles, whilst almost 1 in 
10 IVF cycles are complicated by moderate or severe OHSS (3).  
 
The major cause of OHSS is the use of hCG in current IVF protocols for oocyte maturation (4). Human 
chorionic gonadotrophin binds to the LH receptor and therefore mimics the actions of endogenous LH. 
However, hCG has a much longer circulating half life than LH; this results in overstimulation of the 
corpus luteum which is the underlying cause of OHSS (12). Human chorionic gonadotrophin circulates 
for up to a week after injection (13), whereas with the physiological stimulus, the LH surge only lasts for 
48 hours (14). This overstimulation of the corpus luteum also results in an environment more hostile to 
embryo implantation (5). A more physiological method for oocyte maturation in IVF treatment should 
prevent overstimulation of the corpus luteum and thus the subsequent development of OHSS (5).  
 
Kisspeptin is a neuropeptide which stimulates the HPG axis. Kisspeptin offers a novel approach in IVF 
therapy to improve pregnancy rates and avoid the complication of OHSS. Kisspeptin is the endogenous 
agonist of the G protein-coupled receptor, GPR54 (19-22). The kisspeptin / GPR54 system plays a 
critical role in the hypothalamic regulation of the HPG axis. Inactivating GPR54 mutations in humans 
have been shown to cause hypogonadotrophic hypogonadism (absence of sexual maturation with low 
sex hormones and gonadotrophins) and failure of pubertal development (23-24). GPR54 or kisspeptin 
deficient mice have a similar phenotype with abnormal sexual development, low circulating 
gonadotrophin concentrations, and infertility (23, 25, 26). Furthermore, administration of kisspeptin 
potently stimulates activity of the HPG axis. Acute intracerebroventricular (ICV) or peripheral 
administration of kisspeptin to rodents or primates potently stimulates gonadotrophin release (10, 27). 
Kisspeptin stimulates the release of a limited pool of endogenous GnRH, which results in release of 
endogenous gonadotrophins. (9-11). We have recently demonstrated for the first time that acute 
administration of kisspeptin to healthy male and female volunteers with normal reproductive function, 
and in women with infertility due to hypothalamic amenorrhea potently stimulates the HPG axis without

Version 8; 15/10/2013  
side effects (7, 8, 33). The evidence to date demonstrates that the kisspeptin / GPR54 system is critical 
for normal pubertal development and reproductive function.  
 
Kisspeptin is a critical upstream regulator of GnRH neurones necessary for normal reproductive 
function. Kisspeptin is found in hypothalamic regions important in the regulation of the HPG axis (9). In 
rodents, hypothalamic kisspeptin neurons are activated during proestrus (ie the time of the cycle just 
prior to ovulation), and blockade of the actions of hypothalamic kisspeptin with a specific monoclonal 
antibody abolishes the proestrus LH surge, suggesting that kisspeptin signalling is required for a normal 
menstrual cycle (28). Recent evidence demonstrates that kisspeptin is the physiological regulator of the 
LH surge (6) and exogenous administration of kisspeptin has been shown to induce ovulation in rats 
and sheep (31, 32). In keeping with this, our previous human studies demonstrate that kisspeptin 
stimulates LH release most potently in the pre-ovulatory phase of the menstrual cycle in females with 
regular normal menstrual cycles (8). 
 
The major cause of OHSS in current IVF protocols is the pharmacological use of hCG which is used for 
oocyte maturation (4). Since kisspeptin stimulates the release of physiological levels of GnRH and the 
consequent release of endogenous gonadotrophins (9-11) it should lead to a physiological LH surge 
which would be dependent on the sensitivity of the HPG axis of each woman. A more physiological 
approach for oocyte maturation in IVF treatment would prevent overstimulation of the corpus luteum and 
OHSS in IVF treatment (5). The significant advantage of kisspeptin over current treatments is that its 
effects would depend on the sensitivity of an individual’s HPG axis. This would result in a more 
physiological LH surge and oocyte maturation during IVF treatment, thereby improving safety and 
efficacy of IVF treatment (5).  
 
GnRH antagonists are widely used in IVF protocols to suppress the increase in endogenous LH which 
would otherwise cause premature ovulation (29). These agents bind to GnRH receptors in the pituitary 
gland and competitively inhibit the actions of endogenous GnRH. The onset of the suppression of 
pituitary gonadotrophin release is rapid, as is the recovery of pituitary function after cessation. This 
makes GnRH antagonists ideal agents for short term pituitary suppression (29). In addition since 
pituitary function recovers almost immediately when GnRH antagonist is withdrawn, they allow the 
potential use of physiological stimulators of endogenous gonadotrophins (e.g. kisspeptin) in IVF 
protocols to generate a more physiological LH surge and oocyte maturation in IVF protocols (29).  
 
We hypothesise that use of kisspeptin in place of hCG in IVF protocols will result in the physiological 
release of the endogenous releasable pool of GnRH and subsequent gonadotrophin secretion; this in 
turn will lead to oocyte maturation.  
 
The aim of the current study is to provide proof of concept that administration of kisspeptin can induce 
oocyte maturation in infertile women undergoing IVF treatment. 
 
1.2 
RATIONALE FOR CURRENT STUDY 
 
Research question: Can kisspeptin stimulate oocyte maturation in IVF therapy for infertility ? 
 
Hypothesis: kisspeptin will stimulate oocyte maturation in IVF therapy for infertility  
 
Infertility affects one in six couples in the UK (1). IVF treatment is now widely and successfully used to 
enable infertile couples to conceive. Approximately 45,000 cycles of IVF are performed in Britain each 
year. However, IVF treatment can result in the potentially life threatening condition, OHSS (2). Mild 
forms of OHSS occur in approximately 1 in 3 of all IVF cycles, whilst approximately 1 in 10 IVF cycles 
result in moderate or severe OHSS (3). The major cause of OHSS is the pharmacological use of hCG 
to stimulate oocyte maturation in current IVF protocols (4). The development of a more physiological 
stimulus for oocyte maturation should avoid this dangerous side effect and improve the safety and 
efficacy of IVF treatment (5). Kisspeptin is a hormone which stimulates reproductive hormone secretion 
in animals and is responsible for the endogenous LH surge which results in ovulation (6). In keeping 

The use of kisspeptin in IVF treatment 
Page 10 of 20 
Version 8; 15/10/2013  
with this, exogenous administration of kisspeptin has been shown to induce ovulation in rats and sheep 
(31, 32). We have conducted the first studies of kisspeptin administration to humans; in which we have 
shown that acute administration of kisspeptin potently stimulates reproductive hormone secretion in 
healthy men and women (7, 8), as well as women with infertility due to hypothalamic amenorrhea (33). 
Importantly, we have demonstrated that healthy women with regular menstrual cycles are most sensitive 
to the effects of kisspeptin immediately prior to ovulation (8). Recent evidence demonstrates that 
kisspeptin stimulates the release of a limited pool of endogenous GnRH which results in the release of 
endogenous gonadotrophins (9-11). Therefore, the significant advantage of kisspeptin over current 
treatments is that its effects would depend on the sensitivity of an individual’s HPG axis. This would 
result in a more physiological LH surge and oocyte maturation during IVF treatment, thereby improving 
safety and efficacy of IVF treatment (5).

Kisspeptin to induce oocyte maturation – there will therefore be no randomisation as all women will 
receive kisspeptin 
 
5.2 
UNBLINDING 
This is an open label, dose escalation, phase 2 clinical trial investigating the administration of 
Kisspeptin to induce oocyte maturation and all women will receive at least one dose of kisspeptin. 
Women will receive either one, or two doses of kisspeptin at least 8 hours apart. Women will be 
advised that the first injection will be kisspeptin for all women, but the second injection received may 
be either kisspeptin or saline.

6.1 
TREATMENT ARMS 
All of the women in this study will undergo a standard FSH/GnRH antagonist IVF protocol with luteal 
phase supplementation which is used for women undergoing IVF treatment at Hammersmith Hospital 
under the supervision of Dr Geoff Trew (Director of the IVF Unit) (please see appendix 2). The only 
difference will be that women taking part in the study will have either one or two subcutaneous 
injections of kisspeptin in place of hCG in order to trigger oocyte maturation. This injection will be 
administered by two experienced physicians at the Hammersmith Hospital or in the participant’s home 
according to the patients preference. 
The patients will be administered with the first dose of kisspeptin 12-24 hours after the last injection of 
FSH/GnRH antagonist for final oocyte maturation. Women will be randomised to receive either a 
single dose of kisspeptin (9.6nmol/kg), or two doses of kisspeptin 8-12 hours apart. The optimal 
dosing regimen of kisspeptin will be the dose of kisspeptin which causes the highest level of oocyte 
maturation. 
Since kisspeptin causes a rapid and potent rise in LH release following sc injection we would expect 
that kisspeptin will induce oocyte maturation at a similar timing as when hCG or GnRH are used to 
trigger oocyte maturation which is 32-36 hours after injection (13, 16, 17, 18). In order to determine the 
changes in reproductive hormones which occur during oocyte maturation, participants will be given 
two options for blood testing following injection of kisspeptin. These options will be discussed at 
screening, and participants are entirely free to decline overnight blood sampling without altering their 
study participation or clinical care: 
Option 1. Overnight blood sampling: Participants opting for overnight blood sampling will be admitted 
to the Wellcome / NIHR Clinical Research Facility (CRF), Hammersmith Hospital. Blood will be 
sampled for measurement of plasma LH, FSH, progesterone, kisspeptin and oestradiol. Total blood 
loss will not exceed 100ml, and blood sampling will not be performed more frequently than every 
15min. 
Option 2. Less intensive blood testing: In participants who do not opt into overnight blood sampling, 
plasma LH, FSH, progesterone and oestradiol will be measured immediately before kisspeptin 
injection, on up to six occasions within the first 24h following kisspeptin injection (according to 
participant availability), and then at the time of oocyte retrieval. 
These hormone measurements will determine the time course following kisspeptin injection at which 
an endogenous LH surge occurs which will be used to confirm the timing of oocyte retrieval.  
This study will determine the potential of kisspeptin as a trigger for oocyte maturation in IVF treatment.

PHARMACOVIGILANCE 
 
7.1 
DEFINITIONS   
Adverse Event (AE): any untoward medical occurrence in a patient or clinical trial subject administered 
a medicinal product and which does not necessarily have a causal relationship with this treatment.  An 
AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an IMP, whether or not considered related 
to the IMP. 

The use of kisspeptin in IVF treatment 
Page 13 of 20 
Version 8; 15/10/2013  
 
Adverse Reaction (AR): all untoward and unintended responses to an IMP related to any dose 
administered.  All AEs judged by either the reporting investigator or the sponsor as having reasonable 
causal relationship to a medicinal product qualify as adverse reactions.  The expression reasonable 
causal relationship means to convey in general that there is evidence or argument to suggest a causal 
relationship. 
 
Unexpected Adverse Reaction: an AR, the nature or severity of which is not consistent with the 
applicable product information (eg investigator’s brochure for an unapproved investigational product or 
summary of product characteristics (SmPC) for an authorised product).  When the outcome of the 
adverse reaction is not consistent with the applicable product information this adverse reaction should 
be considered as unexpected.  Side effects documented in the SmPC which occur in a more severe 
form than anticipated are also considered to be unexpected. 
 
Serious Adverse Event (SAE) or Serious Adverse Reaction: any untoward medical occurrence or 
effect that at any dose 
• 
Results in death 
• 
Is life-threatening – refers to an event in which the subject was at risk of death at the time 
of the event; it does not refer to an event which hypothetically might have caused death if 
it were more severe 
• 
Requires hospitalisation, or prolongation of existing inpatients’ hospitalisation 
• 
Results in persistent or significant disability or incapacity 
• 
Is a congenital anomaly or birth defect 
 
Medical judgement should be exercised in deciding whether an AE/AR is serious in other situations.  
Important AE/ARs that are not immediately life-threatening or do not result in death or hospitalisation 
but may jeopardise the subject or may require intervention to prevent one of the other outcomes listed 
in the definition above, should also be considered serious. 
 
Suspected Unexpected Serious Adverse Reaction (SUSAR): any suspected adverse reaction 
related to an IMP that is both unexpected and serious.   
 
7.2 
CAUSALITY 
Most adverse events and adverse drug reactions that occur in this study, whether they are serious or 
not, will be expected treatment-related toxicities due to the drugs used in this study.  The assignment of 
the causality should be made by the investigator responsible for the care of the participant using the 
definitions in the table below. 
 
If any doubt about the causality exists the local investigator should inform the study coordination centre 
who will notify the Chief Investigators.  The pharmaceutical companies and/or other clinicians may be 
asked to advise in some cases. 
 
In the case of discrepant views on causality between the investigator and others, all parties will discuss 
the case.  In the event that no agreement is made, the MHRA will be informed of both points of view.  
 
Relationship 
Description 
Unrelated 
There is no evidence of any causal relationship 
Unlikely 
There is little evidence to suggest there is a causal relationship (e.g. the event 
did not occur within a reasonable time after administration of the trial 
medication).  There is another reasonable explanation for the event (e.g. the 
participant’s clinical condition, other concomitant treatment). 
Possible 
There is some evidence to suggest a causal relationship (e.g. because the 
event occurs within a reasonable time after administration of the trial 
medication).  However, the influence of other factors may have contributed to 

The use of kisspeptin in IVF treatment 
Page 14 of 20 
Version 8; 15/10/2013  
the event (e.g. the participant’s clinical condition, other concomitant 
treatments). 
Probable 
There is evidence to suggest a causal relationship and the influence of other 
factors is unlikely. 
Definitely 
There is clear evidence to suggest a causal relationship and other possible 
contributing factors can be ruled out. 
Not assessable 
There is insufficient or incomplete evidence to make a clinical judgement of the 
causal relationship. 
 
 
7.3 
REPORTING PROCEDURES 
All adverse events will be reported.  Depending on the nature of the event the reporting procedures 
below will be followed.  A flowchart is given below to aid in the reporting procedures. 
 
7.3.1 Non serious AR/AEs 
All such toxicities, whether expected or not, will be recorded in the toxicity section of the relevant case 
report form and sent to the study coordination centre within one month of the form being due.   
 
7.3.2 Serious AR/AEs 
Fatal or life threatening SAEs and SUSARs will be reported on the day that the investigators are aware 
of the event.  The SAE form asks for nature of event, date of onset, severity, corrective therapies given, 
outcome and causality (i.e. unrelated, unlikely, possible, probably, definitely).  The responsible 
investigator (Dr Waljit Dhillo) will sign the causality of the event.  Additional information should be sent 
within 5 days if the reaction has not resolved at the time of reporting.   
 
 
 
SAEs 
An SAE form will be completed and faxed to the Imperial College Joint Research Compliance Office for 
review.  
 
SUSARs  
In the case of serious, unexpected and related adverse events, the staff involved in the study will:  
 
 
Complete the SAE case report form & send it immediately (within 24 hours, preferably by 
fax), signed and dated to Dr Waljit Dhillo together with relevant treatment forms and 
anonymised copies of all relevant investigations.

ASSESSMENT AND FOLLOW-UP  
 
Each participant will be in the study for the period of their IVF treatment, which will be no longer than 
eight weeks. Following this if the patient becomes pregnant they will have routine antenatal follow up 
for the duration of their pregnancy and delivery at Queen Charlottes' Hospital. There will be no 
additional interventions needed during the pregnancy related to the study but we will follow up patients 
until the birth of their child.  
 
8.1 
LOSS TO FOLLOW-UP 
The patients who are lost to follow from this study will be contacted using their telephone and address 
details supplied at the time of entry into the study to ensure safety. As far as data analysis an intention 
to treat analysis will be carried out for this study and sensitivity analysis will be used in data analysis to 
take account of the small number of drop outs that may occur in the study.  
 
8.2 
TRIAL CLOSURE 
The study will stop recruiting patients when the optimal dose of kisspeptin required to trigger oocyte 
maturation has been determined. The optimal dose of kisspeptin will be the dose of kisspeptin which 
causes oocyte maturation in >90% of women (n=15). However, we will continue to follow up all women 
in the study until they have completed their pregnancy.

STATISTICS AND DATA ANALYSIS 
 

The use of kisspeptin in IVF treatment 
Page 16 of 20 
Version 8; 15/10/2013  
Sample size calculation: For the primary endpoint of oocyte maturation in the proposed patient 
population, there is no directly relevant data that has been published previously upon which sample 
sizes estimates could be based. However, there is evidence in the literature (13) of a relationship 
between successful oocyte maturation and rises in luteinising hormone (LH) which can be used as a 
basis for sample size calculations for this study. In that study, successful oocyte maturation occurs 
following a mean rise in LH of 106IU/L at 4hours following a GnRH agonist trigger in a FSH/GnRH 
antagonist IVF protocol. Our previous dose finding studies of kisspeptin on LH release in normal women 
in the preovulatory phase of their menstrual cycle show that kisspeptin (12.8nmol/kg) can increase LH 
by up to 148IU/L with an estimated SD of 78IU/L. Using the 2-group t-test approach, we have calculated 
that with 13 patients in for each dose of kisspeptin tested will have at least 90% power to detect a 
difference of 148IU/L amongst any 2 groups (2-sided 5% significance level without correction for 
multiplicity and common standard deviation of 78 IU/L) (nQuery Advisor Version 5.0. Statistical 
Solutions, Cork, Ireland). This n number is similar to that used in our recent studies of kisspeptin on LH 
release in normal women in the preovulatory phase of their menstrual cycle (n=8) to show a significant 
effect of kisspeptin on LH release compared to controls (8).  It is anticipated that the drop-out rate will 
be less than 10% (based on similar previous studies in these highly motivated infertile patients). 
Therefore, fifteen women for each of the 6 doses of kisspeptin (0.4, 0.8, 1.6, 3.2, 6.4 and 12.8nmol/kg) 
administered will be recruited to allow for dropouts during the study and each woman will only participate 
in the study once. As such a total of 90 women will be recruited to the study. 
 
Data analysis for the study: 
The statistical data analysis will be carried out by Imperial Clinical Trials Unit under the supervision of 
Professor Ashby (Professor of Medical Statistics and Clinical Trials, Imperial College London). An 
intention to treat analysis will be carried out for this study and sensitivity analysis will be used in data 
analysis to take account of the small number of drop outs that may occur in the study. The primary 
analysis of the primary endpoint (oocyte maturation) will employ a logistic model to characterise the 
relationship between dose of kisspeptin and oocycte maturation. Additionally Bayesian analysis 
methods will be employed to characterise the relationship between dose of kisspeptin, LH and oocyte 
maturation.

APPENDIX 1. 
SUMMARY OF INVESTIGATIONS, TREATMENT AND 
ASSESSMENTS 
 
All of the women in this study will undergo a standard FSH/GnRH antagonist IVF protocol with luteal 
phase supplementation which is used as part of routine care for women undergoing IVF treatment at 
Hammersmith Hospital (see appendix 2) under the supervision of Dr Geoff Trew (Director of the IVF 
Unit). The only difference will be that women taking part in the study will have: 
1. a single subcutaneous injection of kisspeptin in place of hCG in order to trigger oocyte 
maturation.  
2.  Plasma LH, FSH, progesterone and oestradiol will be measured immediately before kisspeptin 
injection and then after kisspeptin injectionon up to 6 occasions during the first 24h and finally 
at the time of oocyte retrieval. These hormone measurements will determine the time course 
following kisspeptin injection at which an endogenous LH surge occurs which will be used to 
confirm the timing of oocyte retrieval. 
All of the other procedures that the patients will have are part of routine care and would be the same 
for volunteers not participating in the study. 
 
 
 
 
APPENDIX 2.  
STANDARD FSH/GNRH ANTAGONIST IVF PROTOCOL 
WITH LUTEAL PHASE SUPPLEMENTATION  
All of the women in this study will undergo a standard FSH/GnRH antagonist IVF protocol with luteal 
phase supplementation which is used as part of routine care for women undergoing IVF treatment at 
Hammersmith Hospital (see appendix 2) under the supervision of Dr Geoff Trew (Director of the IVF 
Unit). The current protocol is detailed below. This will be updated according to best clinical care.  
 
Daily subcutaneous (sc) FSH injections (Gonal F) will be commenced on day 2 of the patient’s 
menstrual cycle. Daily GnRH antagonist administration (Cetrotide) will be used to inhibit a premature 

The use of kisspeptin in IVF treatment

Version 8; 15/10/2013  
LH surge and will be started on the 5th day of FSH injections. The patient will attend 5 days after 
commencing the FSH injections for a pelvic ultrasound scan (USS) to determine ovarian follicular 
development. The patient will be asked to attend for further scans according to follicular size and 
response (if the largest follicle is 10-12mm the next USS will be 3 days later, if the largest follicle is 13-
15mm the next USS will be 2 days later, if the largest follicle is 16mm daily USS will be performed). 
When 3 ovarian follicles of ≥ 17mm have developed, the FSH and GnRH antagonist injections will be 
stopped. Kisspeptin will be given in place of hCG at this point in the protocol as detailed in section 6.1 
of the protocol to cause oocyte maturation. 
Thirty two to thirty six hours later, transvaginal ultrasound-directed oocyte retrieval will be carried out. 
Oocyte maturation will be determined using standard criteria (calculations of the percentage of 
metaphase II (MII) oocytes and fertilisation rate (number of two pronuclear (2PN) oocytes / number of 
metaphase oocytes injected) (15). ICSI will be carried out using fresh sperm from the male partner. 
The quality of the embryos will be classified as high quality (score 1), medium quality (score 2), and 
low quality (score 3) as previously described (30). One or two embryos of highest quality will be 
transferred to the uterine cavity of the patient on day 3-5 after oocyte collection. The remaining 
embryos will be frozen for the patient to use in future if required. Progesterone  and oestradiol (at 
dosages recommended by the IVF team) will be started on the morning after oocyte collection until 12 
weeks of pregnancy for luteal phase supplementation. After oocyte retrieval doxycycline (100mg bd) 
will be given for 7 days as well as analgesia as required (diclofenac suppository or paracetamol). 
Women will be followed up according to the standard protocol of the IVF Unit at Hammersmith 
Hospital. Women in whom kisspeptin does not result in oocyte maturation will receive a further IVF 
cycle (i.e. with hCG as a trigger for oocyte maturation) as part of their standard care. Pregnancy will be 
defined biochemically by a plasma βhCG concentration >10iu/l 12 to 16 days after embryo transfer. 
Pregnancy will be defined clinically as an intrauterine gestational sac with a heartbeat 2-3 weeks after 
a positive hCG test. An additional ultrasound scan may also be performed at 7 weeks if there is clinical 
suspicion of an ectopic pregnancy.  In women with a clinical pregnancy, standard pregnancy follow up 
will occur at Queen Charlotte’s Hospital. Pregnancy outcomes and live births will be documented.   
IVF clinicians will make decisions in the best clinical interest of patients to safeguard patient safety 
where necessary as would occur in normal clinical practice.
