Abstract
The purpose of this study is to evaluate the live birth outcome following oocyte thaw in women who underwent social egg freezing at Guy's Hospital, alongside a detailed published literature review to compare published results with the current study. A retrospective cohort study was conducted between January 2016 and March 2022 for all women who underwent egg freezing during this period. Overall, 167 women had 184 social egg freezing cycles. The mean age at freeze was 37.1 years and an average of 9.5 eggs were frozen per retrieval. In total, 16% of the women returned to use their frozen eggs. The mean egg thaw survival rate post egg thaw was 74%. The mean egg fertilisation rate was 67%. The pregnancy rate achieved per embryo transfer was 48% and the live birth rate per embryo transfer was 35%. We also noted that irrespective of age at freezing, a significantly high live birth rate was achieved when the number of eggs frozen per patient was 15 or more. Despite the rapid increase in social egg freezing cycles, the utilisation rate remains low. Pregnancy and live birth rate post thaw are encouraging if eggs are frozen at a younger age and if 15 eggs or more were frozen per patient.

Comparing endometrial preparation methods in frozen embryo transfers - Does a previous live birth make a difference? Eur J Obstet Gynecol Reprod Biol 2023; 284:52-57. [PMID: 36933459 DOI: 10.1016/j.ejogrb.2023.03.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 03/07/2023] [Accepted: 03/10/2023] [Indexed: 03/17/2023]
Abstract
RESEARCH QUESTION Does the outcome of a medicated or natural endometrial preparation for a frozen cycle differ if a patient has previously experienced a failed fresh cycle? DESIGN Retrospective matched case-controlled study to investigate frozen embryo transfer (FET) outcomes in women undergone medicated or natural endometrial preparation, with adjustment to the history of previous live birth. 878 frozen cycles were included for analysis, over a period of 2 years. RESULTS After adjusting for the number of embryos transferred, endometrial thickness and the number of previous embryo transfers, there was no difference in live birth rate (LBR) between medicated-FET and natural-FET groups regardless of the previous fertility outcome (p = 0.08). CONCLUSIONS A previous live birth does not affect the outcome of a subsequent frozen cycle, regardless of whether medicated- or natural endometrial preparation is used.

Abstract
Demand for oocyte freezing in absence of a medical indication is growing as women delay childbirth and seek to extend the window of opportunity for parenthood. The optimum age for oocyte freezing is below 35 years, whereas currently the mean age of women undergoing oocyte freezing in the UK is 38 years. Nearly half of women undergoing oocyte freezing are not in a relationship. The treatment is not publicly funded and the average price for a complete oocyte freezing and thawing cycle, including annual storage fees, could reach over £7000. The live birth rate per oocyte thaw cycle is 18% and is influenced by age at the time of oocyte freezing. Women considering social oocyte freezing should be thoroughly counselled about the efficacy, limitations, cost implications and alternatives to oocyte freezing and provided with the appropriate support to enable a truly informed reproductive choice.

Abstract
To review the cumulative outcome of pre-implantation genetic diagnosis (PGD) cycles performed for prevention of sickle cell disease (SCD). Couples referred for PGD for SCD between April 2012 and October 2017 were included. Ovarian stimulation was performed using a short gonadotrophin-releasing hormone (GnRH) antagonist protocol and follicle-stimulating hormone injections. The GnRH agonist was used to trigger oocyte maturation. Oocytes were fertilised using intracytoplasmic sperm injection. Trophectoderm biopsy was performed on day 5 or 6 followed by vitrification. Genetic testing was done using pre-implantation genetic haplotyping. A total of 60 couples started 70 fresh PGD cycles (mean 1·2 cycles/couple) and underwent a total of 74 frozen-embryo-transfer (FET) cycles (mean 1·3 FET/couple). The mean (SD) female age was 33 (4·4) years and the mean (SD) anti-müllerian hormone level was 22·9 (2·8) pmol/l. The cumulative live-birth rate was 54%/PGD cycle started and 63%/couple embarking on PGD. The rate of multiple births was 8%. The cumulative outcome of PGD treatment for prevention of SCD transmission is high and PGD treatment should be offered to all at-risk couples.

Abstract
A review of studies published between January 1, 1984 and January 31, 2019 was performed with the aim of analysing the efficacy and adverse effects of commonly used adjuvants to in vitro fertilisation. The authors preferentially selected recent systematic reviews and randomised control trials (where available) from an electronic literature search. The review showed that low molecular weight heparin, corticosteroids and embryo glue may be of use in selected patient groups. Other adjuncts (such as growth hormone, assisted hatching, endometrial disruption and dehydroepiandrosterone) cannot currently be recommended as collated results showed no overall benefit to clinical pregnancy rates or live birth rates. There is a significant lack of robust evidence in this field, and areas in particular need of further research have been highlighted. In conclusion, caution should be exercised in prescribing adjuvants in in vitro fertilisation, either individually or in combination as further research is needed to ascertain their efficacy. Many adjuvants carry the risk of adverse effects which should also be considered. Patients should be clearly informed of the evidence, and where it is lacking, for these treatments. There is a need for further good quality trials to address the questions regarding best practice.

Early oocyte denudation does not compromise ICSI cycle outcome: a large retrospective cohort study. Reprod Biomed Online 2018; 37:18-24. [PMID: 29673730 DOI: 10.1016/j.rbmo.2018.03.014] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Revised: 03/10/2018] [Accepted: 03/14/2018] [Indexed: 11/30/2022]
Abstract
This retrospective cohort study of 2051 consecutive fresh non-donor intracytoplasmic sperm injection (ICSI) cycles investigated whether time from oocyte retrieval to denudation, precisely measured and recorded by an operator-independent automated radiofrequency-based system, affected cycle outcome. ICSI cycles were divided into two groups: group I (denudation within <2 h of oocyte retrieval, n = 1118) and group II (denudation 2-5 h after oocyte retrieval, n = 933). Univariate analysis by two-sample t-test or Mann-Whitney test was used, as appropriate. Both groups were comparable with regards to mean number of oocytes retrieved and fertilized normally after ICSI. The mean number of embryos transferred and surplus embryos cryopreserved at the blastocyst stage were similar. There was no significant difference in fertilization, embryo implantation, pregnancy, clinical pregnancy or live birth rates between the groups. Analysis of group I ICSI outcome after subdivision into immediate (up to 30 min) and early (31-119 min) denudation showed no statistically significant differences between the two subgroups. In conclusion, early oocyte denudation within <2 h after retrieval does not appear to compromise ICSI cycle outcome, permitting more efficiency and flexibility in scheduling laboratory workload. As this was a retrospective observational study, further prospective studies are required to confirm the findings.

Abstract
Ovarian hyperstimulation syndrome is a potentially life-threatening, but preventable iatrogenic complication of in vitro fertilisation treatment. In recent years, new strategies have been developed to minimise the risk of ovarian hyperstimulation syndrome after in vitro fertilisation, including better at-risk patient identification prior to starting treatment, the use of a lower human chorionic gonadotrophin dose or alternative medication instead of human chorionic gonadotrophin to induce final oocyte maturation such as gonadotrophin-releasing hormone agonist and kisspeptin in antagonist cycles, cryopreservation of all embryos and delayed embryo transfer, and the use of oral dopamine agonists after oocyte retrieval. In this article, the advantages and limitations of those new developments are discussed and future directions towards establishment of an ovarian hyperstimulation syndrome-free in vitro fertilisation clinic are explored.

Abstract
BACKGROUND The success rate of in-vitro fertilisation (IVF) remains low and many women undergo multiple treatment cycles. A previous meta-analysis suggested hysteroscopy could improve outcomes in women who have had recurrent implantation failure; however, studies were of poor quality and a definitive randomised trial was needed. In the TROPHY trial we aimed to assess whether hysteroscopy improves the livebirth rate following IVF treatment in women with recurrent failure of implantation. METHODS We did a multicentre, randomised controlled trial in eight hospitals in the UK, Belgium, Italy, and the Czech Republic. We recruited women younger than 38 years who had normal ultrasound of the uterine cavity and history of two to four unsuccessful IVF cycles. We used an independent web-based trial management system to randomly assign (1:1) women to receive outpatient hysteroscopy (hysteroscopy group) or no hysteroscopy (control group) in the month before starting a treatment cycle of IVF (with or without intracytoplasmic sperm injection). A computer-based algorithm minimised for key prognostic variables: age, body-mass index, basal follicle-stimulating hormone concentration, and the number of previous failed IVF cycles. The order of group assignment was masked to the researchers at the time of recruitment and randomisation. Embryologists involved in the embryo transfer were masked to group allocation, but physicians doing the procedure knew of group assignment and had hysteroscopy findings accessible. Participants were not masked to their group assignment. The primary outcome was the livebirth rate (proportion of women who had a live baby beyond 24 weeks of gestation) in the intention-to-treat population. The trial was registered with the ISRCTN Registry, ISRCTN35859078. FINDINGS Between Jan 1, 2010, and Dec 31, 2013, we randomly assigned 350 women to the hysteroscopy group and 352 women to the control group. 102 (29%) of women in the hysteroscopy group had a livebirth after IVF compared with 102 (29%) women in the control group (risk ratio 1·0, 95% CI 0·79-1·25; p=0·96). No hysteroscopy-related adverse events were reported. INTERPRETATION Outpatient hysteroscopy before IVF in women with a normal ultrasound of the uterine cavity and a history of unsuccessful IVF treatment cycles does not improve the livebirth rate. Further research into the effectiveness of surgical correction of specific uterine cavity abnormalities before IVF is warranted.

Abstract
OBJECTIVE To assess PGD outcome using FISH analysis in couples with a history of recurrent miscarriage associated with a parental carrier of reciprocal translocation. STUDY DESIGN Couples in whom one partner was a carrier of a reciprocal translocation and had a history of two or more miscarriages and a low risk of a live born offspring with an unbalanced chromosomal rearrangement, underwent PGD treatment between 2000 and 2012. RESULTS 91 couples started 171 fresh and 11 frozen PGD cycles. Of the fresh cycles, 162 (95%) reached oocyte retrieval and 107 (63%) had embryo transfer. In 14 cycles (8%), surplus embryos were cryopreserved. Pregnancy was achieved in 52 fresh PGD cycles, leading to 20 miscarriages and 32 live births. Eleven frozen embryo transfer cycles resulted in two miscarriages and three live births. The overall live birth rate was 19% per fresh and frozen PGD cycle started (35/182) and miscarriage rate was 39% per pregnancy (22/57). The cumulative live birth rate was 32% per couple (29/91). CONCLUSION After PGD for recurrent miscarriage in low-risk reciprocal translocation carriers, the miscarriage risk remains high and chance of live birth is low. For those translocation carriers, natural conception may be a better option.

Abstract
In this systematic review and meta-analysis, the effect of intrauterine HCG infusion before embryo transfer on IVF outcomes (live birth rate, clinical pregnancy rate and spontaneous aboretion rate) was investigated. Searches were conducted on MEDLINE, EMBASE and The Cochrane Library. Randomized studies in women undergoing IVF and intracytoplasmic sperm injection comparing intrauterine HCG administration at embryo transfer compared with no intrauterine HCG were eligible for inclusion. Eight randomized controlled trials were eligible for inclusion in the meta-analysis. A total of 3087 women undergoing IVF and intracytoplasmic sperm injection cycles were enrolled (intrauterine HCG group: n = 1614; control group: n = 1473). No significant difference was found in the live birth rate (RR 1.13; 95% CI 0.84 to 1.53) and spontaneous abortion rate (RR 1.00, 95% CI 0.74 to 1.34) between women who received intrauterine HCG and those who did not receive HCG. Although this review was extensive and included randomized controlled trials, no significant heterogeneity was found, and the overall included numbers are relatively small. In conclusion the current evidence does not support the use of intrauterine HCG administration before embryo transfer. Well-designed multicentre trials are needed to provide robust evidence.

Abstract
A systematic review and meta-analysis was conducted to evaluate the relationship between the extent of sperm DNA damage and live birth rate (LBR) per couple and the influence of the method of fertilization on treatment outcome. Searches were conducted on MEDLINE, EMBASE and Cochrane Library. Six studies were eligible for inclusion in the meta-analysis. Overall, LBR increased signficantly in couples with low sperm DNA fragmentation compared with those with high sperm DNA fragmentation (RR 1.17, 95% CI 1.07 to 1.28; P = 0.0005). After IVF and intracytoplasmic sperm injection (ICSI), men with low sperm DNA fragmentation had significantly higher LBR (RR 1.27, 95% CI 1.05 to 1.52; P = 0.01) and (RR 1.11, 95% CI 1.00 to 1.23, P = 0.04), respectively. A sensitivity analysis showed no statistically significant difference in LBR between low and high sperm DNA fragmentation when ICSI treatment was used (RR 1.08, 95% CI 0.39 to 2.96; P = 0.88). High sperm DNA fragmentation in couples undergoing assisted reproduction techniques is associated with lower LBR. Well-designed randomized studies are required to assess the role of ICSI over IVF in the treatment of men with high sperm DNA fragmentation.

Abstract
OBJECTIVE To evaluate the safety of abdominal myomectomy for very large fibroid uteri, and to assess the effect of relevant confounding variables on the occurrence of major peri-operative complications. STUDY DESIGN A cohort study of 200 abdominal myomectomies for fibroid uteri of 16 gestational weeks or greater. Logistic regression analysis was used to examine the influence of important clinical variables on the risk of complications. A systematic literature search was conducted for evidence related to peri-operative morbidity associated with abdominal myomectomy for very large fibroid uteri. RESULTS The mean (±standard deviation) uterine size was 21±5 weeks. The overall rate of major complications was 30%. Peri-operative bleeding necessitating blood transfusion occurred in 49 (24.5%) cases. During surgery, two patients had bowel injury, two had bladder injury, seven women returned to theatre and two (1%) had hysterectomy. Four patients were re-admitted within 14 days of surgery. Multivariable logistic regression analysis showed that the risk of major complications was significantly higher in cases with a uterine size of 20 gestational weeks or more [odds ratio (OR) 3.4, 95% confidence interval (CI) 1.1-10.2; p=0.03], where 10 or more fibroids were removed (OR 3.5, 95% CI 1.1-10.8; p=0.05) and where midline skin incision was required (OR 6.1, 95% CI 1.7-22.3; p=0.006). On comparison of primary vs repeat abdominal myomectomy, there was significantly higher blood loss (mean 1023±1112 ml vs 579±787 ml; p=0.02) and risk of major complications in the repeat myomectomy group (40% vs 5%; p<0.001). The systematic review identified only one study that reported a comparable risk of major complications related to abdominal myomectomy for very large fibroid uteri. CONCLUSION The risk of organ injury, hysterectomy, re-operation or hospital re-admission after abdominal myomectomy for very large fibroid uteri is low, but the procedure is associated with a significant risk of bleeding necessitating blood transfusion. This risk is increased after repeat myomectomy, and in patients with a uterine size of 20 gestational weeks or larger, requiring removal of 10 or more fibroids, and requiring a midline skin incision.

The search for a practice model to reduce miscarriage after assisted reproduction. Reprod Biomed Online 2011; 23:695-6.

Abstract
The analysis of 52,874 clinical pregnancies recorded on the Australian and New Zealand Assisted Reproduction Database (ANZARD) between 2004 and 2008 showed that maternal age and obstetrics history are closely related to the risk of miscarriage, and that the transfer of fresh embryos is associated with fewer miscarriages than transfer of frozen-thawed embryos. It also suggested a higher miscarriage rate is associated with the transfer of thawed blastocysts compared with transfer of thawed cleavage-stage embryos or the blastocysts that ensued from them. Therefore, the authors proposed a practice model of transferring fresh blastocysts and freezing of cleavage-stage embryos to reduce the miscarriage rate after assisted reproduction. This model may have practical limitation and would need validation in a randomized trial. Retrospective analysis of large national databases is useful in identifying trends and generating hypothesis, but evaluation of these hypotheses in randomized trials remains necessary for objective validation.

Outcomes of ovarian stimulation in a two-day oocyte collection week with PGD cycles compared to a five-day oocyte collection week with conventional IVF/ICSI cycles. HUM FERTIL 2011; 14:254-60.

Abstract
We assessed the outcomes of ovarian stimulation in a two-day egg collection (EC) week with preimplantation genetic diagnosis (PGD) cycles (N = 307) compared to a five-day EC week with conventional in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles (N = 2,417). The mean (SD) age of women undergoing PGD was 34 (3.97) and 35 (3.85) for IVF/ICSI (P < 0.001), the number of oocytes collected was 13 (7.37) and 11 (7.02), (P < 0.001), while the mean (SD) number of fertilized oocytes was 8 (5.09) and 6 (4.58), respectively (P < 0.001). The clinical pregnancy rate per embryo transfer (ET) was 37% with PGD and 38% with IVF/ICSI (P = 0.49), while the implantation rate was 0.35 and 0.30, respectively (P = 0.05). After adjusting for age and confounding variables including the number of oocytes collected and fertilized normally, the mode of treatment (PGD or IVF/ICSI) had no effect on clinical pregnancy (P = 0.48). In conclusion, scheduling of PGD cycles to a two-day EC week did not compromise the outcomes of ovarian stimulation when compared to a five-day EC week with conventional IVF/ICSI cycles. This can allow the provision of a more patient friendly service, increase the flexibility of satellite PGD services, and facilitate cycle programming with the genetics team providing PGD.
