STUDY QUESTION Does a policy of elective freezing of embryos, followed by frozen embryo transfer result in a higher healthy baby rate, after first embryo transfer, when compared with the current policy of transferring fresh embryos? SUMMARY ANSWER This study, although limited by sample size, provides no evidence to support the adoption of a routine policy of elective freeze in preference to fresh embryo transfer in order to improve IVF effectiveness in obtaining a healthy baby. WHAT IS KNOWN ALREADY The policy of freezing all embryos followed by frozen embryo transfer is associated with a higher live birth rate for high responders but a similar/lower live birth after first embryo transfer and cumulative live birth rate for normal responders. Frozen embryo transfer is associated with a lower risk of ovarian hyperstimulation syndrome (OHSS), preterm delivery and low birthweight babies but a higher risk of large babies and pre-eclampsia. There is also uncertainty about long-term outcomes, hence shifting to a policy of elective freezing for all remains controversial given the delay in treatment and extra costs involved in freezing all embryos. STUDY DESIGN, SIZE, DURATION A pragmatic two-arm parallel randomized controlled trial (E-Freeze) was conducted across 18 clinics in the UK from 2016 to 2019. A total of 619 couples were randomized (309 to elective freeze/310 to fresh). The primary outcome was a healthy baby after first embryo transfer (term, singleton live birth with appropriate weight for gestation); secondary outcomes included OHSS, live birth, clinical pregnancy, pregnancy complications and cost-effectiveness. PARTICIPANTS/MATERIALS, SETTING, METHODS Couples undergoing their first, second or third cycle of IVF/ICSI treatment, with at least three good quality embryos on Day 3 where the female partner was ≥18 and MAIN RESULTS AND THE ROLE OF CHANCE Of the 619 couples randomized, 307 and 309 couples in the elective freeze and fresh transfer arms, respectively, were included in the primary analysis. There was no evidence of a statistically significant difference in outcomes in the elective freeze group compared to the fresh embryo transfer group: healthy baby rate {20.3% (62/307) versus 24.4% (75/309); risk ratio (RR), 95% CI: 0.84, 0.62 to 1.15}; OHSS (3.6% versus 8.1%; RR, 99% CI: 0.44, 0.15 to 1.30); live birth rate (28.3% versus 34.3%; RR, 99% CI 0.83, 0.65 to 1.06); and miscarriage (14.3% versus 12.9%; RR, 99% CI: 1.09, 0.72 to 1.66). Adherence to allocation was poor in the elective freeze group. The elective freeze approach was more costly and was unlikely to be cost-effective in a UK National Health Service context. LIMITATIONS, REASONS FOR CAUTION We have only reported on first embryo transfer after randomization; data on the cumulative live birth rate requires further follow-up. Planned target sample size was not obtained and the non-adherence to allocation rate was high among couples in the elective freeze arm owing to patient preference for fresh embryo transfer, but an analysis which took non-adherence into account showed similar results. WIDER IMPLICATIONS OF THE FINDINGS Results from the E-Freeze trial do not lend support to the policy of electively freezing all for everyone, taking both efficacy, safety and costs considerations into account. This method should only be adopted if there is a definite clinical indication. STUDY FUNDING/COMPETING INTEREST(S) NIHR Health Technology Assessment programme (13/115/82).

INTRODUCTION There is increasing evidence that vitamin D has widespread tissue effects. In addition to osteoporosis, vitamin D deficiency has been associated with cardiovascular disease, diabetes, cancer, infections and neurodegenerative disease. However, the effect of vitamin D supplementation on non-skeletal outcomes requires clarification, especially in postmenopausal women. AIM This position statement provides an evidence-based overview of the role of vitamin D in the health of postmenopausal women based on observational and interventional studies. MATERIALS AND METHODS Literature review and consensus of expert opinion. RESULTS AND CONCLUSIONS Vitamin D status is determined by measuring serum 25-hydroxyvitamin D levels. Concentrations

Progestogen administration is required to oppose naturally produced or administered estrogens to provide endometrial protection. Within HRT regimens, this should be delivered for at least the same duration as that produced during the luteal phase of the monthly cycle and in the recommended doses to protect against the risk of endometrial hyperplasia and endometrial cancer. This includes progestogens administered for 12–14 days a month in sequential regimens and continuous daily intake in continuous combined HRT regimens. Shorter durations and lower doses of progestogen intake are likely to be associated with an increased risk of breakthrough bleeding, endometrial hyperplasia, and endometrial cancer.

ObjectiveTo explore the views of members of the British Menopause Society on the management of women with unscheduled bleeding on hormone replacement therapy.Study designAn electronic cross-sectional questionnaire survey.Main outcome measuresInvestigations, treatment options and preferences for the management of women with unscheduled bleeding on hormone replacement therapy.ResultsA total of 91/178 (51%) clinicians investigate patients with unscheduled bleeding within three to six months of starting sequential hormone replacement therapy (seq-HRT) versus 83/178 (47%) for continuous combined hormone replacement therapy (con-HRT). A total of 52/178 (29%) versus 54/178 (30%) would investigate unscheduled bleeding continuing beyond six months while 18/178 (10%) versus 26/178 (15%) would investigate within three months. Assessment is requested as urgent by 88/176 (50%) clinicians, routine by 47/176 (27%) and a two-week-wait-suspected cancer referral by 41/176 (23%). A total of 97/178 (55%) clinicians would continue seq-HRT and refer versus 117/178 (66%) for con-HRT. A total of 46/178 (26%) clinicians would change the progestogen preparation in women with unscheduled bleeding on seq-HRT. For women on con-HRT, 12/178 (7%) clinicians would change to seq-HRT and 8/178 (5%) to the Mirena IUS. The Mirena IUS is the preferred progestogen for 81/178 (45%) of clinicians when prescribing hormone replacement therapy.ConclusionsThere is a varied approach in the practise amongst British Menopause Society members to managing women with unscheduled bleeding on hormone replacement therapy. Further research is needed to determine the optimal assessment pathways for women with unscheduled bleeding on hormone replacement therapy.

Objective To investigate the experience of remote outpatient menopause service delivery by clinicians and patients during the COVID-19 pandemic. Methods Two surveys explored the experiences of patients and clinicians separately. Patients attending menopause clinics in the UK were directed to an online survey which included questions on demographics and on their experience of their most recent appointment. A clinician survey was shared to members of the British Menopause Society (BMS) via email and was made available on the BMS website. It contained questions on clinic characteristics and clinicians’ experience of delivering remote menopause consultations. Surveys were available for completion between 01/12/2020 and 10/02/2021. Results Of 180 patients who completed the patient survey, 52% felt remote consultations were the same or better than face-to-face consultations, and 90% of patients felt a choice between remote and face-to-face consultations should be offered. Patients overall were satisfied with many aspects of care, though numerous problems were highlighted with appointment administration. Of 76 clinicians who completed the clinician survey, most found remote patient consultations either no different or a bit worse than face-to face consultations but found that they offered more flexibility. In some cases, significant rescheduling was necessary to accommodate for the clinical needs of the consultation. Conclusion A ‘one-size-fits-all’ approach to managing the delivery of menopause care is not supported by patients or clinicians. There must be a robust process in place to avoid problems with appointment scheduling and associated communications. Lessons learned from the pandemic can help to provide holistic menopause care.

This care pathway from the European Menopause and Andropause Society (EMAS) provides an updated pathway for monitoring and guidance of women at midlife, focusing on those approaching the end of the reproductive life-cycle, going through the menopausal transition and beyond. The care pathway is written by professionals involved in women's health and provides a stepwise individualized approach, stratified according to needs, symptoms and reproductive stage. Furthermore, the pathway provides details on screening for chronic diseases related to menopause and ageing. Treatment options for climacteric symptoms range from menopausal hormone therapy to non-hormonal alternatives and lifestyle modifications. Therapy should be tailored to personal needs and wishes. The pathway aims to offer a holistic, balanced approach for monitoring middle-aged women, aiming to control health problems effectively and ensure healthy ageing.

Objective To assess the acceptability and perception of postmenopausal women, to two different hormone replacement therapy regimens, in relation to the control of their symptoms and development of adverse effects. Study design Prospectively recruited postmenopausal women, Main outcome measures Symptom control and development of adverse effects. Results Seventy-one individuals were screened, with baseline data available for 67 subjects. A total of 190 questionnaires were returned. The most commonly reported symptoms were low energy levels, vasomotor symptoms and sexual dysfunction. The prevalence of adverse effects ranged between 57.89 and 87.50%, with a reduction seen in the transdermal oestradiol + micronised progesterone arm (73.91% at 3-months, decreasing to 57.89% at 12-months; p = 0.33), compared to the transdermal oestradiol + medroxyprogesterone acetate arm (76.92% at 3-months, increasing to 87.50% at 12-months; p = 0.69). The main reported adverse effects were bloating, weight change and psychological symptoms. A significant difference was documented between the groups after set intervals, with a greater proportion reporting breast tenderness after 3-months (p = 0.01), lower numbers reporting mood swings at 6-months (p = 0.01) and irritability at 12-months (p = 0.03) in the transdermal oestradiol + micronised progesterone arm compared to the transdermal oestradiol + medroxyprogesterone acetate arm. Conclusions The acceptability of both regimens was high despite adverse effects, but tolerability of transdermal oestradiol combined with micronised progesterone appeared to be better with fewer women reporting psychological concerns.

Background: Polycystic ovary syndrome (PCOS) is a common heterogeneous endocrine disorder. The prevalence of PCOS varies depending on which criteria are used to make the diagnosis, but can be as high as 15%–20%. Aim and objectives: To review the demographic details, presenting symptoms, biochemical features and management in women with PCOS and differentiate patients who have polycystic ovarian morphology (PCOM) and have hypothalamic amenorrhoea. Method: Retrospective observational study of 300 consecutive new cases with suspected PCOS were referred to the reproductive endocrinology clinic in a tertiary referral hospital (Kings college hospital, London) from 2008-2015. Electronic medical records were reviewed and Microsoft Excel software was used for data collection and analysis. Inclusion and exclusion criteria’s: All patients with suspected PCOS fulfilling Rotterdam criteria were included in the study. Phenotypically similar androgen excess disorders like congenital adrenal hyperplasia (CAH), androgen secreting-tumor and Cushing’s syndrome were excluded. Results: The mean (+/-SD) age was 30 (+/-6.7) years [range 14-49]. A total of 213 (71%) had oligomenorrhoea, 61 (20.3%) had amenorrhoea, while 26 (8.6%) had regular cycles. 135 (45%) presented with subfertility, while 93 (31%) had hirsutism. Mean (+/-SD) FSH and LH were 5.5 IU/L (+/-2.8) and 17.8 IU/L (+/-7.9), respectively, while mean (+/-SD) estradiol level was 253.4 pmol/L (+/-267.1). 27/61 (44.2%) women with amenorrhoea, had low estradiol [mean (+/-SD)

In the early part of 2021, the government launched a call for evidence to inform the development of the Women's Health Strategy with the objective of better understanding women's experiences of the health and care system and to help improve the health and wellbeing of women. The British Menopause Society Medical Advisory Council and the BMS Board of Trustees recommendations specific to the menopause and post reproductive health in relation to all six core themes included in the call for evidence assessing the different areas of women's health are discussed in this document.

INTRODUCTION The menopause, or the cessation of menstruation, is a stage of the life cycle which will occur in all women. Managing perimenopausal and postmenopausal health is a key issue for all areas of healthcare, not just gynecology. AIM To provide recommendations for the curriculum of education programs for healthcare professionals worldwide, so that all can receive high quality training on menopause. MATERIALS AND METHODS Literature review and consensus of expert opinion. SUMMARY RECOMMENDATIONS Training programs for healthcare professionals worldwide should include menopause and postmenopausal health in their curriculum. It should include assessment, diagnosis and evidence-based management strategies.

Urogenital atrophy describes the multiple changes in urogenital tissue quality, commonly due to hypoestrogenism associated with the menopause and ageing. These changes can result in pain and bleeding, most notably in association with sexual intercourse. The impact of urogenital atrophy on sexual function is determined by several factors, including a reduction in blood flow to the vulva and vagina, and a decrease in vaginal secretions. Sexual intimacy remains an important aspect of relationships for older women and enquiry about symptoms of urogenital atrophy should be routinely included in all consultations about menopause and in women aged ≥45 years attending for cervical screening. This would help to remove a major barrier, restricting access to diagnosis and treatment for affected women, who find the subject difficult to broach. Other hurdles to accessing treatment include limited research, the cost of treatment, and patients’ fear of hormonal treatment options.1 There are several key research surveys that demonstrate valuable information that could aid in advancing current clinical practice. These include the European REVIVE Survey2 and VIVA-LATAM.3 The REVIVE survey was conducted in Germany, Spain, Italy, and the UK (3768 postmenopausal women aged 45–75 years participated), while the VIVA-LATAM survey was conducted in Latin American countries including Argentina, Brazil, …

To compare the difference between micronised progesterone (MP) and medroxyprogesterone acetate (MPA) in combination with transdermal oestradiol (t-EThe European Society for Cardiology has identified carotid femoral pulse wave velocity (cfPWV) as the gold standard cardiogenic biomarker for risk stratification of arterial disease. Menopause has been shown to augment the age-dependent increase in arterial stiffness, with hormone replacement therapy (HRT) being the mainstay of management of women diagnosed with EMPOI.A pilot randomised prospective open-label trial. Women were randomised to either cyclical MP (Utrogestan® 200mg) or MPA (Provera® 10mg) in conjunction with t-ECarotid-femoral pulse wave velocity (cfPWV).PWV did not significantly change from baseline in either treatment arm. MP + t-EThe positive changes in traditional markers were not reflected in the cardiogenic biomarker, cfPWV, which has demonstrated a higher positive predictive value for cardiovascular events than traditional measurements.

Menopause is a major life event that can affect women in several ways. Its onset marks the end of the reproductive life cycle, and its impact can be both short and long term. Menopause is often a gradual process, preceded by a transitional period known as perimenopause. The average age of menopause in the UK is 51. The clinical manifestations of menopause result from the eventual exhaustion of oocytes within the ovaries. This leads to a chronic hypo-estrogenic state, which in the short term causes menopausal symptoms and over a long term, has an impact on bone and cardiovascular health. There has been a steep drop in the prescription of hormone replacement therapy (HRT) following the publication of the Women's Health Initiative Study and the Million Women Study. It is currently estimated that approximately a million women in the UK are taking HRT for control of their menopausal symptoms. This review summarises the current recommendations for HRT use in menopausal women. The benefits of HRT in improving the symptoms of menopause are discussed as well as the potential role of HRT in managing long-term sequelae is covered. Evidence pertaining to the potential risks associated with HRT is also be reviewed.

Menopause is a major life event affecting all women in a variety of ways, both short and long term. All women should have access to accurate information, available in all forms and through all recognised sources. All healthcare professionals should have a basic understanding of the menopause and know where to signpost women for advice, support and treatment whenever appropriate. Every primary care team should have at least one nominated healthcare professional with a special interest and knowledge in menopause. All healthcare professionals with a special interest in menopause should have access to British Menopause Society Menopause Specialists for advice, support, onward referral and leadership of multidisciplinary education. With the introduction of the comprehensive British Menopause Society Principles and Practice of Menopause Care programme, the society is recognised throughout the UK as the leading provider of certificated menopause and post reproductive health education and training for healthcare professionals. Restrictions imposed by the coronavirus pandemic have been a springboard for the British Menopause Society to bring innovations to the services provided for our membership and for healthcare professionals throughout the UK.

Background: Embryos created following in-vitro fertilisation (IVF) are usually replaced within the uterus within a few days (fresh embryo transfer). It has been suggested that elective freezing of all embryos followed by transfer at a later date (freeze-all) could make treatment safer and more effective. The aim of this trial was to compare the clinical and cost-effectiveness of a strategy of freeze-all versus fresh embryo transfer. Methods: A two arm, non-blinded, parallel group pragmatic randomised trial was conducted across 18 IVF clinics in the UK. Couples undergoing IVF, where the woman was

Contains fulltext : 238753.pdf (Publisher’s version ) (Open Access) Premature ovarian insufficiency (POI) is an increasing public health problem with a prevalence now approaching 4%. POI results in adverse effects on the skeleton and central nervous system as well as disturbances of metabolic and cardiological factors that predispose to a major increased risk of cardiovascular disease (CVD). This article reviews the effects of the premature loss of ovarian function on lipids and lipoproteins, glucose and insulin metabolism, body composition, hemostasis and blood pressure, together with effects on the development of metabolic syndrome and diabetes mellitus. The article examines the effects of POI on vascular endothelial function and inflammation that result in arterial disease, and reviews the effects of hormone replacement therapy (HRT) on these various metabolic processes and on cardiovascular outcomes. It is essential that women with POI receive hormonal treatment to help prevent the development of CVD, and that this treatment is continued at least until the normal age of menopause. It appears that HRT has a more favorable effect than the combined oral contraceptive, but larger clinical trials are needed to establish the optimal treatment. Other therapeutic measures may need to be added to correct existing metabolic abnormalities and, in particular, attention to lifestyle factors such as diet and exercise must be encouraged.

Contains fulltext : 233788.pdf (Publisher’s version ) (Open Access) Women undergo important changes in sex hormones throughout their lifetime that can impact cardiovascular disease risk. Whereas the traditional cardiovascular risk factors dominate in older age, there are several female-specific risk factors and inflammatory risk variables that influence a woman's risk at younger and middle age. Hypertensive pregnancy disorders and gestational diabetes are associated with a higher risk in younger women. Menopause transition has an additional adverse effect to ageing that may demand specific attention to ensure optimal cardiovascular risk profile and quality of life. In this position paper, we provide an update of gynaecological and obstetric conditions that interact with cardiovascular risk in women. Practice points for clinical use are given according to the latest standards from various related disciplines (Figure 1).

Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication of assisted reproductive treatment. Management of women with severe OHSS has traditionally included hospitalisation for close monitoring and supportive treatment. The aim of this review is to assess the evidence for safety and efficacy of outpatient management of severe OHSS. A systematic review of studies describing outpatient management options was performed. Current guidance from advisory bodies was also reviewed. Outpatient management has been found in observational studies to be safe and cost-effective compared to inpatient management. Paracentesis of ascitic fluid seems to be effective treatment for severe OHSS along with supportive management including maintenance of fluid balance and preventative measures against thrombo-embolism. GnRH antagonist was shown in few studies to be effective in treatment of early severe OHSS although further research is required to assess its role in this context. Appropriate outpatient set up and protocols are essential to provide safe outpatient management for women with severe OHSS.

ObjectiveThis study correlates the transvaginal ultrasound findings with histopathology results in women who present with unscheduled bleeding on hormone replacement therapy.Study designRetrospective analysis of 469 consecutive cases with unscheduled bleeding on hormone replacement therapy (203 patients on sequential hormone replacement therapy (seq-HRT) and 266 patients on continuous combined hormone replacement therapy (con-HRT)).Main outcome measuresOutcomes of endometrial assessment in women with unscheduled bleeding on hormone replacement therapy.ResultsNormal appearance of the endometrium on pelvic ultrasound was seen in 62% patients on seq-HRT and 43% of women on con-HRT. These women required no further assessment and were discharged. Histological assessment showed normal endometrial tissue in 22% of women on seq-HRT and 22% of con-HRT group. Benign endometrial polyps were noted in 8% of women on seq-HRT versus 18% of women on con-HRT. Hyperplasia without atypia was noted in 0.5% of woman on seq-HRT versus 0.4% of women on con-HRT while atypical hyperplasia/endometrial cancer was noted in 2% of women on seq-HRT versus 1% of women on con-HRT.ConclusionWomen who present with unscheduled bleeding on hormone replacement therapy both on sequential and continuous combined regimens can be reassured that the risk of pathology is low.

BACKGROUND: Endometrial scratching (with the use of a pipelle biopsy) is a technique proposed to facilitate embryo implantation and increase the probability of pregnancy in women undergoing in vitro fertilization (IVF). METHODS: We conducted a pragmatic, multicenter, open-label, randomized, controlled trial. Eligible women were undergoing IVF (fresh-embryo or frozen-embryo transfer), with no recent exposure to disruptive intrauterine instrumentation (e.g., hysteroscopy). Participants were randomly assigned in a 1:1 ratio to either endometrial scratching (by pipelle biopsy between day 3 of the cycle preceding the embryo-transfer cycle and day 3 of the embryo-transfer cycle) or no intervention. The primary outcome was live birth. RESULTS: A total of 1364 women underwent randomization. The frequency of live birth was 180 of 690 women (26.1%) in the endometrial-scratch group and 176 of 674 women (26.1%) in the control group (adjusted odds ratio, 1.00; 95% confidence interval, 0.78 to 1.27). There were no significant between-group differences in the rates of ongoing pregnancy, clinical pregnancy, multiple pregnancy, ectopic pregnancy, or miscarriage. The median score for pain from endometrial scratching (on a scale of 0 to 10, with higher scores indicating worse pain) was 3.5 (interquartile range, 1.9 to 6.0). CONCLUSIONS: Endometrial scratching did not result in a higher rate of live birth than no intervention among women undergoing IVF.

A B S T R A C T Objective: To assess patients’ satisfaction and the intermediate and long-term patterns of symptom progression following uterine artery fibroid embolization (UAE). Study design: Intermediate (2–6 years) and long-term (9–14 years) follow-up questionnaire survey to women who underwent UAE during the period 1996–2000, at a tertiary referral centre. Results: The mean (SD) age of women at the time of embolization was 43 (5.58) years. A total of 142/197 (72.1%) women had the embolization in view of heavy menstrual periods, while 87/197 (44%) indicated a desire to retain fertility. 160/197 (81.7%) women who completed Q1 reported an improvement in menstrual symptoms compared to 41/80 (51.2%) for Q2 [p < 0.01]. The majority indicated they would recommend the procedure to a friend (Q1: 165 (83.8%), Q2: 62/80 (77.5%)) [p = 0.75]. 23/80 (28.8%) required further surgical treatment following UAE, and within the latter group, only 7/23 (30.4%) were satisfied with the embolization. 22/80 (27.5%) tried for a pregnancy following the procedure, and of these 3/22 (13.6%) had a live birth. The mean (SD) age at the menopause for women who returned Q2 was 49.1 (4.91) years. Conclusions: The majority of women were satisfied with the embolization and noted an improvement in menstrual symptoms. However, this improvement diminished over time following the embolization, and over a quarter of women required further surgical intervention. Findings from this study may provide useful information in counselling women undergoing UAE and help guide clinicians in their patient selection criteria when discussing the procedure.

The menopausal transition may be a challenging period in a woman's life. For some, the menopausal symptoms may last for many years and can result in significant physical and emotional consequences. Adverse publicity regarding hormone replacement therapy (HRT) use over the last decade has resulted in a significant decline in HRT use, and as a result many women have been left to cope with their menopausal symptoms. This article discusses the current evidence on the role of HRT in the management of menopausal women, including its benefits and potential risks. It also summarises the recent HRT guidelines published by the British Menopause Society.

Objective To assess the association between risk of venous thromboembolism and use of different types of hormone replacement therapy. Design Two nested case-control studies. Setting UK general practices contributing to the QResearch or Clinical Practice Research Datalink (CPRD) databases, and linked to hospital, mortality, and social deprivation data. Participants 80 396 women aged 40-79 with a primary diagnosis of venous thromboembolism between 1998 and 2017, matched by age, general practice, and index date to 391 494 female controls. Main outcome measures Venous thromboembolism recorded on general practice, mortality, or hospital records. Odds ratios were adjusted for demographics, smoking status, alcohol consumption, comorbidities, recent medical events, and other prescribed drugs. Results Overall, 5795 (7.2%) women who had venous thromboembolism and 21 670 (5.5%) controls had been exposed to hormone replacement therapy within 90 days before the index date. Of these two groups, 4915 (85%)and 16 938 (78%) women used oral therapy, respectively, which was associated with a significantly increased risk of venous thromboembolism compared with no exposure (adjusted odds ratio 1.58, 95% confidence interval 1.52 to 1.64), for both oestrogen only preparations (1.40, 1.32 to 1.48) and combined preparations (1.73, 1.65 to 1.81). Estradiolhad a lower risk than conjugated equine oestrogen for oestrogen only preparations (0.85, 0.76 to 0.95) and combined preparations (0.83, 0.76 to 0.91). Compared with no exposure, conjugated equine oestrogen with medroxyprogesterone acetate had the highest risk (2.10, 1.92 to 2.31), and estradiol with dydrogesterone had the lowest risk (1.18, 0.98 to 1.42). Transdermal preparations were not associated with risk of venous thromboembolism, which was consistent for different regimens (overall adjusted odds ratio 0.93, 95% confidence interval 0.87 to 1.01). Conclusions In the present study, transdermal treatment was the safest type of hormone replacement therapy when risk of venous thromboembolism was assessed. Transdermal treatment appears to be underused, with the overwhelming preference still for oral preparations.

Study question Has the change in donor anonymity legislation in UK affected the recruitment of men wanting to be sperm donors and also affected the attitudes of the practitioners who provide donor sperm treatment? Summary answer We have performed fewer IUI and IVF treatments using donor sperm following the change in legislation in April 2005 than before. However, we have seen an overall increase in men wanting to donate their sperm, including a small increase in men from ethnic minorities. What is known already Sweden, which removed donor anonymity in 1985, had an initial drop in men wanting to donate and then 10 years later started to have an increase. The Human Fertilisation and Embryology Authority (HFEA) and other studies in the UK have shown an overall downward trend, but have not been able to compare large time scales either side of the change in legislation. Study design, size, duration This was a retrospective descriptive study that looked at all men who approached the clinic between the years 2000 and 2010, i.e. 5 years either side of the change in legislation (April 2005). Overall, we had 24 men wanting to be donors prior to the rule change and 65 men after the rule change. We also investigated the total number of all treatments with donor sperm, and this included a total of 1004 donor sperm treatments prior to the change in legislation and 403 donor sperm treatments after the change in legislation. Participants, setting, methods The study was set in an NHS IVF clinic in South East London. We compared the indicators of service provision, provider practices and donor attitudes, in the period between April 2000 and March 2005 (Group A) with those between April 2005 and March 2010 (Group B), i.e. 5 years either side of the change in legislation. Main results There were 875 IUI treatments and 129 IVF or ICSI treatments in Group A and 325 IUI and 78 IVF/ICSI treatments in Group B with the use of donor sperm, of which, 11.9% (119 out of 1004) in Group A and 39.5% (159 out of 403) in Group B were with donor sperm recruited by our unit. The clinical pregnancy rate per cycle of treatment in Group A was (86 out of 875) 9.8% for IUI and (27 out of 129) 20.9% for IVF/ICSI and in Group B (32/325) 9.8% and (28 out of 78) 35.9%, respectively. There was a sharp yearly fall in donor sperm treatments from 2004. Twenty-four men were screened in Group A, of which 18 (75.0%) were recruited for long-term storage and 12 (50%) were registered as donors with the HFEA when the sperm was used, whereas in Group B, 65 men were screened, 53 (82.0%) were recruited and 24 (36.92%) were registered as donors. Six (24.0%) men in Group A failed in screening because of poor semen analysis when compared with 9 (13.8%) men in Group B. The majority of post-recruitment dropouts were because of loss of follow-up or withdrawal of consent. More donors in Group A were white (92.0 versus 77.0%) and born in UK (92.0 versus 68.0%) when compared with those in Group B. Donors in Group B were more likely to be single (46.0 versus 4.0%) and to have informed their relevant partner of donation (71.0 versus 54.0%) when compared with those in Group A. 83.0% of donors in Group A were heterosexual when compared with 69.0% in Group B. The primary reason for donating in both groups of potential donors was 'wanting to help' (46.0% 'altruistic donors' in Group A versus 72.0% in Group B). Fewer donors in Group B (37%) had specific restrictions about the use of their sperm when compared with 46.0% in Group A. Limitations, reasons for caution As this was a retrospective study, there is a chance for the introduction of bias. Wider implications of the findings We have shown that despite no active in-house recruitment procedures, we are managing to recruit more potential sperm donors after the change in UK legislation, and we are able to meet the demand for treatments with in-house recruited donor sperm that is a reassuring finding for donor sperm treatment services in the wider UK.

Key content Raised levels of prolactin are common and can result in the inhibition of ovulation and infertility. This review summarises the published evidence on the association between hyperprolactinaemia and fertility in women. The evidence on the assessment and treatment of the subfertile woman with clinical or biochemical evidence of hyperprolactinaemia is discussed. The management of hyperprolactinaemia in pregnancy is discussed. Learning objectives To understand the effect of prolactin on ovulation and female reproductive function. To be able to carry out an initial assessment of the infertile woman presenting with hyperprolactinaemia. To understand the management of hyperprolactinaemia in pregnancy. Ethical issues Whether hyperprolactinaemia in the presence of ovulation in the subfertile woman should be treated is debatable. There are safety issues regarding the use of dopamine agonists (bromocriptine, cabergoline and quinagolide) in pregnancy.

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.
