Introduction: Dehydroepiandrosterone (DHEA) and its sulfate DHEAS, which are the most abundant steroids in women, decline with age. We have shown association between low sexual function and low circulating DHEAS levels in women.
Aim: The aim of this study was to evaluate whether restoration of circulating DHEA levels in postmenopausal women to the levels seen in young individuals improves sexual function.
Methods: Ninety-three postmenopausal women not using concurrent estrogen therapy were enrolled in a 52-week randomized, double-blind, placebo controlled trial and received either DHEA 50 mg or placebo (PL) daily.
Main Outcome Measures: Efficacy was assessed through 26 weeks. The main outcome measures were the change in total satisfying sexual events (SSE) and the change in the Sabbatsberg Sexual Self-Rating Scale (SSS) total score. Secondary measures were the Psychological General Well-Being Questionnaire (PGWB), and the Menopause-Specific Quality of Life Questionnaire (MENQOL). Hormonal levels, adverse events (AEs), serious adverse events (SAEs) and clinical labs were evaluated over 52 weeks.
Results: Eighty-five participants (91%) were included in the 26-week efficacy analysis. There were no significant differences between the DHEA and PL groups in the change in total SSE per month or the SSS, PGWB, and MENQOL change scores. Overall AE reports and number of withdrawals as a result of AEs were similar in both groups; however more women in the DHEA group experienced androgenic effects of acne and increased hair growth.
Conclusions: In this study treatment of postmenopausal women with low sexual desire with 50 mg/day DHEA resulted in no significant improvements in sexual function over PL therapy over 26 weeks.

Background: To assess the effectiveness of tumor biomarkers in distinguishing epithelial ovarian tumors (EOTs) and guiding clinical decisions across each Ovarian-Adnexal Reporting and Data System (O-RADS) MRI risk category, the aim is to prevent unnecessary surgeries for benign lesions, avoid delays in treating malignancies, and benefit individuals requiring fertility preservation or those intolerant to over-extensive surgery.
Methods: A total of 54 benign, 104 borderline, and 203 malignant EOTs (BeEOTs, BEOTs and MEOTs) were enrolled and retrospectively assigned risk scores. The role of tumor biomarkers in diagnosing and managing EOTs within each risk category was evaluated by combining receiver operating characteristic (ROC) curves with clinicopathological characteristics.

Introduction: Cancer treatments have a detrimental impact on the quality of life (QoL) of young women with breast cancer (YWBC). Research exploring QoL trajectories has been mostly centered on postmenopausal women. Here we report longitudinal changes across all QoL domains and associated factors in YWBC.

This study assessed the feasibility of miR17 ~ 92-based antiresorptive strategy by determining the effects of conditional transgenic (cTG) overexpression of miR17 ~ 92 in myeloid cells on bone and osteoclasts. Osteoclasts of male and female cTG mutant mice each showed 3- to fivefold overexpression of miR17 ~ 92 cluster genes compared to those of age- and sex-matched wildtype (WT) littermates. Male but not female cTG mutant mice had more trabecular and cortical bones as well as lower bone resorption reflected by reduction in osteoclast number and resorbing surface.

Background: Women's elevated risk of Alzheimer's disease (AD) compared to men remains unclear, with gonadal hormones proposed as potential contributors. This study aimed to explore the association between follicle-stimulating hormone (FSH), estradiol (E2), neuropsychological AD stages, and cerebral Aβ deposition.
Methods: A total of 679 subjects were included in the study (N = 198 for cognitively normal (CN), N = 373 for mild cognitive impairment (MCI), and N = 108 for AD dementia groups).
