Caster Semenya could be forced to undertake hormone therapy for future Olympics

Study shows performance-boosting effects of testosterone in female athletes, reopening controversial debate about intersex and hyperandrogenous competitorsUsing testosterone to categorise male and female athletes isn ’t perfect, but it’s the best solution we haveCaster Semenya, the Olympic 800m champion, may be banned from competing at future Games unless she undergoes hormone replacement therapy (HRT) or even surgery in the wake of a landmark study into athletes with raised testosterone levels which has just been published.The International Association of Athletics Federations, the world governing body, commissioned research which has produced the most conclusive evidence yet that female athletes with very high levels of naturally occurring testosterone receive significant performance-enhancing benefits in competition.Continue reading...

CONCLUSIONS: Biallelic mutations in POLG may be associated with ovarian dysfunction. This study has improved our understanding of POLG-related genetic mutations in ovarian dysfunction, and the mode of inheritance of certain sequence variants. This information will assist genetic counseling and precision medicine in the future. PMID: 29992832 [PubMed - as supplied by publisher]

CONCLUSIONS: Currently, there is insufficient high-quality evidence to inform women considering HRT after treatment for endometrial cancer. The available evidence (both the single RCT and non-randomised evidence) does not suggest significant harm, if HRT is used after surgical treatment for early-stage endometrial cancer. There is no information available regarding use of HRT in higher-stage endometrial cancer (FIGO stage II and above). The use of HRT after endometrial cancer treatment should be individualised, taking account of the woman's symptoms and preferences, and the uncertainty of evidence for and against HRT use. ...

Abstract Increased proliferation and breast cancer risk has been observed in postmenopausal women receiving estrogen (E) + progestin hormone replacement therapy (HRT). Progestin action is mediated through two progesterone receptor (PR) isoforms, PRA and PRB, with unique transcriptional activity and function. The current study examines hormonal regulation of PR isoforms in the normal postmenopausal human breast and the mechanism by which progestins increase proliferation and breast cancer risk. Archival benign breast biopsies from postmenopausal and premenopausal women, and luminal breast tumor biopsies from postme...

Conclusions: Decisions regarding the use of HT in women who undergo BSO after detection of a BRCA mutation must be individualized based on careful consideration of the risks and benefits. However, the risks of a subsequent cancer diagnosis appear small, particularly in regards to the benefits of treatment afforded by HT.

Conclusions:The available literature suggests that HT is a viable option for the primary prevention of cardiovascular disease in postmenopausal women. Newer trials will likely verify this assessment. If this is enough to change clinical practice, however, remains to be seen given the general fear of HT by many with prescriptive authority, and also the women in our care. Objective: Clinical trials in menopause have undergone much scrutiny over the years. This has led to significant shifts in the treatment of symptomatic menopause and a substantial impact on women. We aim to delineate the key studies contributing to this...

Macedo Menopause is a natural event that occurs in women around the age of 50 years, causing irregularities in the menstrual cycle until its complete end, due to the hormonal deficit, especially estrogen, that causes several unpleasant urogenital and vasomotor symptoms. Hormone replacement therapy has many benefits, but should be prescribed with caution in women with a history of stroke, thromboembolic events, certain types of cance...

ConclusionsMore than 50% in the total cohort had hormone replacement. Although adherence was generally good, this study shows that hormone replacement therapy may be improved. This may be achieved by better individualization of the treatment and by providing specific information to patients regarding both long‐term and short‐term hormonal effects and side effects.
