ABSTRACT
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.

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 <42 years of age were eligible. Those using donor gametes, undergoing preimplantation genetic testing or planning to freeze all their embryos were excluded. IVF/ICSI treatment was carried out according to local protocols. Women were followed up for pregnancy outcome after first embryo transfer following randomization. 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).

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).

Premature ovarian insufficiency (POI) is a condition in which there is a decline in ovarian function in women who are younger than 40 years resulting in a hypo-oestrogenic state with elevated gonadotrophins and oligomenorrhoea/amenorrhoea. This leads to short term complications of menopausal symptoms and long-term effects on bone and cardiovascular health, cognition as well as the impact of reduced fertility and sexual function associated with this condition. It is managed by sex steroid replacement either with HRT or combined hormonal contraception until the age of natural menopause (51) and this can provide a beneficial role with both symptom control and minimising the long-term adverse effects associated with this condition. Women who undergo a menopause between 40 and 45 years are deemed to have an "early menopause". The limited data available for this group suggest that they also have an increased morbidity if not adequately treated with hormone therapy. As such, women who have an early menopause should be managed in a similar way to those with POI, with the recommendation that they should take HRT at least until the natural age of menopause. This is the same for induced menopause that is caused by medical or surgical treatment that impacts the ovaries. It is important to ensure early diagnosis and access to specialist care to help support and manage these patients to reduce the symptoms and risks of long-term complications. This review looks at the diagnosis, causes, short and long-term complications and management of POI, early and induced menopause.

Unscheduled bleeding on hormone replacement therapy (HRT) can affect up to 40% of users. In parallel with the increase in HRT prescribing in the UK, there has been an associated increase in referrals to the urgent suspicion of cancer pathway for unscheduled bleeding. On behalf of the British Menopause Society (BMS) an expert review panel was established, including primary and secondary care clinicians with expertise in the management of menopause, with representatives from key related organisations, including the Royal College of Obstetricians & Gynaecologists, the British Gynaecological Cancer Society, British Society for Gynaecological Endoscopy, Royal College of General Practitioners and Faculty of Sexual and Reproductive Health, and service development partners from NHS England and GIRFT (Getting it Right First Time). For each topic, a focused literature review was completed to develop evidence led recommendations, where available, which were ratified by consensus review within the panel and by guideline groups.

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.

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 <20 ng/ml (<50 nmol/l) and <10 ng/ml (<25 nmol/l) are considered to constitute vitamin D deficiency and severe deficiency, respectively. Observational data suggest an association between vitamin D deficiency and adverse health outcomes in postmenopausal women, although they cannot establish causality. The evidence from randomized controlled trials concerning vitamin D supplementation is not robust, since many studies did not consider whether people were deficient at baseline. Moreover, high heterogeneity exists in terms of the population studied, vitamin D dosage, calcium co-administration and duration of intervention. Concerning skeletal health, vitamin D deficiency is associated with low bone mass and an increased risk of fractures. Vitamin D supplementation at maintenance doses of 800-2000 IU/day (20-50 µg/day), after repletion of vitamin D status with higher weekly or daily doses, may be of benefit only when co-administered with calcium (1000-1200 mg/day), especially in the elderly populations and those with severe vitamin D deficiency. Concerning cardiovascular disease, vitamin D deficiency is associated with an increased prevalence of cardiovascular risk factors, mainly metabolic syndrome, type 2 diabetes mellitus and dyslipidemia. Vitamin D deficiency, especially its severe form, is associated with an increased risk of cardiovascular events (coronary heart disease, stroke, mortality), independently of traditional risk factors. Vitamin D supplementation may have a modestly beneficial effect on lipid profile and glucose homeostasis, especially in obese individuals or those ≥60 years old and at doses of ≥2000 IU/day (≥50 µg/day). However, it has no effect on the incidence of cardiovascular events. Concerning cancer, vitamin D deficiency is associated with increased incidence of and mortality from several types of cancer, such as colorectal, lung and breast cancer. However, the data on other types of gynecological cancer are inconsistent. Vitamin D supplementation has no effect on cancer incidence, although a modest reduction in cancer-related mortality has been observed. Concerning infections, vitamin D deficiency has been associated with acute respiratory tract infections, including coronavirus disease 2019 (COVID-19). Vitamin D supplementation may decrease the risk of acute respiratory tract infections and the severity of COVID-19 (not the risk of infection). Concerning menopausal symptomatology, vitamin D deficiency may have a negative impact on some aspects, such as sleep disturbances, depression, sexual function and joint pains. However, vitamin D supplementation has no effect on these, except for vulvovaginal atrophy, at relatively high doses, i.e., 40,000-60,000 IU/week (1000-1500 IU/week) orally or 1000 IU/day (25 µg/day) as a vaginal suppository.

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.

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.

OBJECTIVE: To compare the difference between micronised progesterone (MP) and medroxyprogesterone acetate (MPA) in combination with transdermal oestradiol (t-E2) on cardiovascular disease (CVD) risk markers in women diagnosed with an early menopause and premature ovarian insufficiency (EMPOI). BACKGROUND: The 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. STUDY DESIGN: A pilot randomised prospective open-label trial. Women were randomised to either cyclical MP (Utrogestan® 200mg) or MPA (Provera® 10mg) in conjunction with t-E2 (Evorel® Patches 50mcg/day) for 12 months. Seventy-one subjects were screened, and baseline data are available for 57 subjects. MAIN OUTCOME MEASURE: Carotid-femoral pulse wave velocity (cfPWV). RESULTS: PWV did not significantly change from baseline in either treatment arm. MP + t-E2 demonstrated a positive effect on traditional CVD markers, with a significant improvement seen in cardiac output (CO) (0.71±1.01mL/min, 95% CI 0.20 to 1.21) and reduction in diastolic blood pressure (DBP) (-3.43±6.31mmHg, 95% Cl -6.57 to -0.29) and total peripheral resistance (TPR) (-0.15±0.19mmHgâ minâ mL-1, 95% CI -0.24 to -0.05) after 12 months. MPA + t-E2, in contrast, did not demonstrate significant changes from baseline in traditional haemodynamic parameters. CONCLUSION: The 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.

OBJECTIVE: To compare the impact of micronized progesterone (MP) or medroxyprogesterone acetate (MPA) in combination with transdermal estradiol (t-E2) on traditional coagulation factors and thrombin generation parameters in postmenopausal women diagnosed with premature ovarian insufficiency or early menopause. METHOD: Randomized prospective trial conducted in women diagnosed with premature ovarian insufficiency or early menopause and an intact uterus, recruited over 28âmonths. All participants were prescribed t-E2 and randomized to either cyclical MP or MPA using a web-based computer randomization software, Graph Pad. Thrombin generation parameters were measured at baseline and repeated after 3-months. Traditional hemostatic biomarkers were measured at baseline and repeated after 3, 6, and 12-months. Seventy-one participants were screened for the study, of whom 66 met the inclusion criteria. In total, 57 participants were randomized: 44 completed the thrombin generation assessment arm of the study, whilst 32 completed 12-months of the traditional coagulation factor screening component of the trial. RESULTS: Thrombin generation parameters did not significantly change from baseline after 3-months duration for either progestogen component when combined with t-E2, unlike the traditional coagulation factors. Protein C activity, free Protein S, and Antithrombin III levels decreased with time in both treatment arms. CONCLUSION: Fluctuations in traditional hemostatic biomarkers were not reproduced by parallel changes in thrombin generation parameters that remained neutral in both groups compared with baseline. The absence of statistically significant changes in thrombin generation for the first 3-months of hormone therapy use is reassuring and would suggest a neutral effect of both progestogens on the global coagulation assay.

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.

BACKGROUND: Freezing all embryos, followed by thawing and transferring them into the uterine cavity at a later stage (freeze-all), instead of fresh-embryo transfer may lead to improved pregnancy rates and fewer complications during in vitro fertilisation and pregnancies resulting from it. OBJECTIVE: We aimed to evaluate if a policy of freeze-all results in a higher healthy baby rate than the current policy of transferring fresh embryos. DESIGN: This was a pragmatic, multicentre, two-arm, parallel-group, non-blinded, randomised controlled trial. SETTING: Eighteen in vitro fertilisation clinics across the UK participated from February 2016 to April 2019. PARTICIPANTS: Couples undergoing their first, second or third cycle of in vitro fertilisation treatment in which the female partner was aged < 42 years. INTERVENTIONS: If at least three good-quality embryos were present on day 3 of embryo development, couples were randomly allocated to either freeze-all (intervention) or fresh-embryo transfer (control). OUTCOMES: The primary outcome was a healthy baby, defined as a live, singleton baby born at term, with an appropriate weight for their gestation. Secondary outcomes included ovarian hyperstimulation, live birth and clinical pregnancy rates, complications of pregnancy and childbirth, health economic outcome, and State-Trait Anxiety Inventory scores. RESULTS: A total of 1578 couples were consented and 619 couples were randomised. Most non-randomisations were because of the non-availability of at least three good-quality embryos (n = 476). Of the couples randomised, 117 (19%) did not adhere to the allocated intervention. The rate of non-adherence was higher in the freeze-all arm, with the leading reason being patient choice. The intention-to-treat analysis showed a healthy baby rate of 20.3% in the freeze-all arm and 24.4% in the fresh-embryo transfer arm (risk ratio 0.84, 95% confidence interval 0.62 to 1.15). Similar results were obtained using complier-average causal effect analysis (risk ratio 0.77, 95% confidence interval 0.44 to 1.10), per-protocol analysis (risk ratio 0.87, 95% confidence interval 0.59 to 1.26) and as-treated analysis (risk ratio 0.91, 95% confidence interval 0.64 to 1.29). The risk of ovarian hyperstimulation was 3.6% in the freeze-all arm and 8.1% in the fresh-embryo transfer arm (risk ratio 0.44, 99% confidence interval 0.15 to 1.30). There were no statistically significant differences between the freeze-all and the fresh-embryo transfer arms in the live birth rates (28.3% vs. 34.3%; risk ratio 0.83, 99% confidence interval 0.65 to 1.06) and clinical pregnancy rates (33.9% vs. 40.1%; risk ratio 0.85, 99% confidence interval 0.65 to 1.11). There was no statistically significant difference in anxiety scores for male participants (mean difference 0.1, 99% confidence interval -2.4 to 2.6) and female participants (mean difference 0.0, 99% confidence interval -2.2 to 2.2) between the arms. The economic analysis showed that freeze-all had a low probability of being cost-effective in terms of the incremental cost per healthy baby and incremental cost per live birth. LIMITATIONS: We were unable to reach the original planned sample size of 1086 and the rate of non-adherence to the allocated intervention was much higher than expected. CONCLUSION: When efficacy, safety and costs are considered, freeze-all is not better than fresh-embryo transfer. TRIAL REGISTRATION: This trial is registered as ISRCTN61225414. FUNDING: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 25.

During in vitro fertilisation, eggs and sperm are mixed in a laboratory to create embryos. An embryo is placed in the womb 25 days later (fresh-embryo transfer) and the remaining embryos are frozen for future use. Initial research suggested that freezing all embryos followed by thawing and replacing them a few weeks later could improve treatment safety and success. Although these data were promising, the data came from small studies and were not enough to change practice and policy. We conducted a large, multicentre, clinical trial to evaluate the two strategies: fresh-embryo transfer compared with later transfer of frozen embryos. We also compared the costs of both strategies during in vitro fertilisation treatment, pregnancy and delivery. This study was conducted across 18 clinics in the UK from 2016 to 2019, and 619 couples participated. Couples were allocated to one of two strategies: immediate fresh-embryo transfer or freezing of all embryos followed later by transfer of frozen embryo. The study's aim was to find out which type of embryo transfer gave participants a higher chance of having a healthy baby. We found that freezing all embryos followed by frozen-embryo transfer did not lead to a higher chance of having a healthy baby. There were no differences between strategies in the number of live births, the miscarriage rate or the number of pregnancy complications. Fresh-embryo transfer was less costly from both a health-care and a patient perspective. A routine strategy of freezing all embryos is not justified given that there was no increase in success rates but there were extra costs and delays to embryo transfer.

OBJECTIVE: The purpose of this study was to investigate the perinatal outcome of prenatally diagnosed congenital talipes equinovarus. METHODS: This was a retrospective observational study of all cases of prenatally diagnosed congenital talipes equinovarus referred to a major tertiary fetal medicine unit. Cases were identified from the fetal medicine and obstetric databases and pregnancy details and delivery outcome data obtained. Details of termination of pregnancy, number of patients undergoing karyotyping as well as details of prenatal classification of severity were recorded. RESULTS: A total of 174 cases were identified. Of these, outcome data was available for 88.5% (154/174) of the pregnancies. Eighty three (47.7%) of cases were isolated and 91 cases (52.3%) were associated with additional abnormalities. There was a significant difference in birth weights between the two cohorts. Bilateral abnormality tended to be more severe. A high caesarean section rate was noted overall and a high preterm delivery rate seen in the isolated group. CONCLUSION: This study is important because it provides contemporary data that can be used to counsel women prenatally. In particular, the raised risk of preterm delivery and caesarean section as well as the increased severity of the condition when both feet are affected should be discussed. The poor perinatal outcome when additional anomalies are present and the increased risk of aneuploidy are also important factors.

OBJECTIVE: To explore the views of members of the British Menopause Society on the management of women with unscheduled bleeding on hormone replacement therapy. STUDY DESIGN: An electronic cross-sectional questionnaire survey. MAIN OUTCOME MEASURES: Investigations, treatment options and preferences for the management of women with unscheduled bleeding on hormone replacement therapy. RESULTS: A 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. CONCLUSIONS: There 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.

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.
