RESUMEN

PURPOSE: Pre-implantation genetic testing for aneuploidies (PGT-A) is a technique used as part of in vitro fertilisation to improve outcomes. Despite the upward trend in women utilising PGT-A, data on women's motivations and concerns toward using the technology, and perceptions having undergone the process, remain scarce. METHODS: This cross-sectional survey, based at a fertility clinic in the UK, utilised an electronic questionnaire to assess the motivations of women who undergo PGT-A and their perceptions and attitudes toward PGT-A after using it. RESULTS: One hundred sixty-one women responded. The most significant motivating factors to undergo PGT-A were to improve the probability of having a baby per cycle (9.0 ± 2.1) and enhance the chance of implantation (8.8 ± 2.5). The least important motivations were reducing the number of embryos transferred per cycle (2.7 ± 3.3) and saving money by reducing the number of procedures required (4.6 ± 3.4). The most significant concerning factors identified included not having embryos to transfer (5.7 ± 3.4) and the potential for embryo damage (5.2 ± 3.3). The least concerning factors included religious (0.6 ± 1.7) or moral (1 ± 2.2) concerns. The majority of women were satisfied/very satisfied following treatment (n = 109; 68%). The proportion of those who were satisfied/very satisfied increased to 94.2% (n = 81) following a successful outcome, and reduced to 43.5% (n = 27) in those who had an unsuccessful outcome or had not undergone embryo transfer (p < 0.001). CONCLUSION: This study highlights that perceptions amongst women who use PGT-A are mostly positive. We also demonstrate a significant association between satisfaction and reproductive outcomes, with those who achieve a live birth reporting more positive perceptions toward PGT-A.

RESUMEN

INTRODUCTION: Social egg freezing enhances reproductive autonomy by empowering women with the capacity to delay their childbearing years, while preserving the opportunity to maintain biological relation with subsequent offspring. However, age-related obstetric complications, economic implications and the risk of unsuccessful future treatment make it a controversial option. Despite the upward trend in women electively cryopreserving their eggs, there is limited data about the women's perceptions, having undergone the process. The aim of this study was to investigate the motivations of women who have undergone social egg freezing, identify their perceptions following treatment, and assess potential feelings of regret. MATERIAL AND METHODS: This cross-sectional survey, based at a fertility clinic in the UK, used an electronic questionnaire to assess the motivations and perceptions of women who underwent social egg freezing between 1 January 2008 and 31 December 2018. RESULTS: One hundred questionnaires were distributed, and 85 women responded (85% response rate). The most frequent reason for freezing oocytes was not having a partner with 56 (70%) women saying it "definitely" influenced their decision. The majority of women (83%; n = 68) knew there was a chance of treatment failure in the future and that a live birth could not be guaranteed. More than half (n = 39; 51%) disagreed or strongly disagreed that the 10-year UK storage limit is fair. One-third of respondents (n = 17; 33%) felt the storage time should be indefinite and 29% (n = 15) believed it should be up to the age of 50. Twenty percent (n = 15) of the women who underwent social egg freezing have successfully had a baby or are currently pregnant, half (n = 8; 53%) of whom conceived spontaneously and a quarter (n = 4; 26%) used their stored oocytes. In all, 91% (n = 73) had no regrets over their decision to undergo social egg freezing. CONCLUSIONS: We demonstrate herein important and novel insights into the motivations and perceptions of women from a UK population who have undergone social egg freezing. Despite potential physical, psychological, and financial burdens, only a small minority of women experience regret after social egg freezing. We also highlight clear discontent with the Human Fertilisation & Embryology Authority storage limit among social egg freezers in the UK.

RESUMEN

PURPOSE: Uterine adenosarcomas (UAs) account for 5-8% of cases of uterine sarcomas. Treatment includes total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO). Fertility preservation is an emerging concept in gynaecology oncology and is particularly relevant in UA, where cases are diagnosed as young as 15-year-old. This manuscript demonstrates a case of UA which was treated conservatively, achieved successful livebirths and underwent completion hysterectomy after two decades of follow-up. METHOD: This was a retrospective case note review. RESULTS: An 18-year-old nulliparous woman presented with abnormal vaginal bleeding. Ultrasound identified an endometrial polyp, which was histologically diagnosed as low-grade adenosarcoma. She was advised to undergo TAH and BSO, but instead decided to preserve her fertility and opted for conservative management. She was monitored with pelvic ultrasound, hysteroscopy and endometrial biopsy bi-annually, with annual pelvic magnetic resonance imaging for 10 years which was uneventful. 11 years post-operatively she conceived following in-vitro fertilization (IVF) but suffered a miscarriage at 16 weeks likely due to cervical incompetence. She subsequently conceived with twins. She delivered spontaneously preterm at 28 weeks. Both children are alive and well. After 20 years of follow-up, she underwent a laparoscopic hysterectomy with no evidence of recurrence. She remains disease free. CONCLUSION: Whilst radical completion surgery should be advised in UA, this case, in addition to all published conservatively managed cases of UA, demonstrates that conservative management is possible in appropriately selected women. Intensive monitoring post-operatively is essential owing to the risk of recurrence; however, this may pose deleterious side effects which require consideration.

RESUMEN

Objective: To assess the prevalence of menstrual disorders and the perceived effect of menstrual cycles upon performance in elite athletes. Methodology: A longitudinal survey in the form of a questionnaire was sent to female track and field athletes at British Athletics every 6 months, over a five-year period between 1st October 2014 and 1st October 2019 in the United Kingdom (UK). Results: 128 athletes completed an average of 4.2 ± 2.9 questionnaires across the study period. The mean age of menarche was 14.2 ± 1.4 years, 13.4 ± 1.3 years and 12.8 ± 1.4 years in endurance, power, and thrower athletes respectively (p < 0.05). Two-thirds (66%; n = 82) reported consistently regular cycles, 30% (n = 37) irregular at some point during the period of observation and 4% (n = 5) were amenorrhoeic. 87 athletes (68%) reported dysmenorrhoea and 40 (31%) menorrhagia. More than three quarters (76.8%; n = 96) described their cycle negatively affected performance. Amongst those who reported when the negative impact occurred (n = 91), 40% (n = 36) reported this in the late luteal phase and 35% (n = 32) during the early follicular phase. 79% (n = 100) of athletes reported at least one cyclical symptom, of which bloating, lower back and pelvic pain were most frequently experienced. Conclusion: This data highlights the complex interrelationship between women's health and elite athletic performance. Athletes perceive a negative impact from their menstrual cycles upon performance with a desire to manage these more effectively, particularly during competition. Female reproductive health expertise in the multi-disciplinary management of elite athletes is required.

RESUMEN

Increasing numbers of females are participating in elite sports, with a record number having competed at the Tokyo Olympic Games. Importantly, the ages of peak performance and fertility are very likely to coincide; as such, it is inevitable that pregnancy will occur during training and competition. Whilst there is considerable evidence to promote regular exercise in pregnancy, with benefits including a reduction in hypertensive disorders, gestational diabetes, and reduced rates of post-natal depression, few studies have been conducted which include elite athletes. Indeed, there are concerns that high-intensity exercise may lead to increased rates of miscarriage and preterm labour, amongst other pregnancy-related complications. There is minimal guidance on the obstetric management of athletes, and consequently, healthcare professionals frequently adopt a very conservative approach to managing such people. This narrative review summarises the evidence on the antenatal, intrapartum, and postpartum outcomes in elite athletes and provides recommendations for healthcare providers, demonstrating that generally, pregnant athletes can continue their training, with a few notable exceptions. It also summarises the physiological changes that occur in pregnancy and reviews the literature base regarding how these changes may impact performance, with benefits arising from pregnancy-associated cardiovascular adaptations at earlier gestations but later changes causing an increased risk of injury and fatigue.

RESUMEN

Despite improvements in assisted reproduction techniques (ARTs), live birth rates remain suboptimal, particularly in women with advanced maternal age (AMA). The leading cause of poor reproductive outcomes demonstrated in women with AMA, as well as women with recurrent miscarriage and repetitive implantation failure, is thought to be due to high rates of embryonic aneuploidy. Preimplantation genetic testing for aneuploidies (PGT-A) aims to select an euploid embryo for transfer and therefore improve ART outcomes. Early PGT-A studies using fluorescent in situ hybridization on mainly cleavage-stage biopsies failed to show improved delivery rates and, in certain cases, were even found to be harmful. However, the development of comprehensive chromosome screening, as well as improvements in culture media and vitrification techniques, has resulted in an emerging body of evidence in favor of PGT-A, demonstrating higher implantation, pregnancy, and live birth rates. While there are concerns regarding the potential harm of invasive biopsy and the cost implications of PGT-A, the introduction of noninvasive techniques and the development of new high-throughput methods which lower costs are tackling these issues. This review aims to assess the evidence for PGT-A, address possible concerns regarding PGT-A, and also explore the future direction of this technology.

RESUMEN

Ultrasound is a readily available, safe and portable imaging modality that is widely applied in gynecology. However, there is limited guidance for its use intra-operatively especially with complex gynecological procedures. This narrative review examines the existing literature published on the use of intraoperative ultrasound (IOUS) in benign gynecology and in gynecological oncology. We searched for the following terms: 'intraoperative,' 'ultrasonography,' 'gynecology' and 'oncology' using Pubmed/Medline. IOUS can minimize complications and facilitate difficult benign gynecological procedures. There is also a role for its use in gynecological oncology surgery and fertility-sparing surgery. The use of IOUS in gynecological surgery is an emerging field which improves visualization in the surgical field and aids completion of minimally invasive techniques.
