BACKGROUND: Since the biological properties of propolis depend to the plants that can be found in a specific region, propolis from unexplored regions attracts the attention of scientists. Ethanolic extract of Cameroonian propolis (EEP) is used to treat various ailments including gynecological problems and amenorrhea. Since there were no scientific data to support the above claims, the present study was therefore undertaken to assess estrogenic properties of Cameroonian propolis. METHODS: To achieve our goal, the ability of EEP to induce MCF-7 cells proliferation in E-screen assay as well as to activate estrogen receptors α (ERα) and β (ERβ) in cell-based reporter gene assays using human embryonic kidney cells (HEK293T) transfected with ERs was tested...

BACKGROUND: The vaginal microbiome is an important site of bacterial-mammalian symbiosis. This symbiosis is currently best characterized for humans, where lactobacilli dominate the microbial community and may help defend women against infectious disease. However, lactobacilli do not dominate the vaginal microbiota of any other mammal studied to date, raising key questions about the forces that shape the vaginal microbiome in non-human mammals. RESULTS: We used Illumina sequencing of the bacterial 16S rRNA gene to investigate variation in the taxonomic composition of the vaginal microbiota in 48 baboons (Papio cynocephalus), members of a well-studied wild population in Kenya...

Postpartum contraception is important to prevent unintended pregnancies. Assisting women in achieving recommended inter-pregnancy intervals is a significant maternal-child health concern. Short inter-pregnancy intervals are associated with negative perinatal, neonatal, infant, and maternal health outcomes. More than 30% of women experience inter-pregnancy intervals of less than 18 months in the United States. Provision of any contraceptive method after giving birth is associated with improved inter-pregnancy intervals...

Premature ovarian insufficiency (POI) affects 1-2% of women under 40 years. BMP15 variants have been described in POI. We studied a family with two sisters compound heterozygous for deletions in the BMP15 gene on chromosome Xp11.22 yielding a human "knockout-like" effect: a c.151_152delGA deletion yielded a p.Glu51IlefsTer27 mutation transmitted by the hemizygous father and a c.189_198delAGGGCATTCAinsTG deletion/insertion yielded a p.Glu64AlafsTer12 mutation transmitted by the heterozygous mother. Both deletions resulted in frameshifts with premature stop codons at positions 78 and 76 in the proregion, precluding mature BMP15 production...

ANCA mediated vasculitis mainly occur between the fourth and fifth decade of life; therefore, it is very uncommon to see pregnant patients with the disease. Vasculitis may affect significantly the course of pregnancy; in turn pregnancy can change the course of vasculitis. We report a 20 years old woman with ANCA-mediated renal vasculitis lasting 10 years who consulted with a pregnancy of 15 weeks. She was in remission and had amenorrhea attributed to ovarian toxicity due to cyclophosphamide. Pregnancy had an uneventful course with spontaneous delivery at the 37th week, giving birth to a healthy newborn...

BACKGROUND: Neuroendocine carcinoma of the gynecologic tract is rare and poses a significant clinical challenge because of tumor heterogeneity and lack of standardized guidelines for treatment. Ovotestis refers to the histology of a gonad that contains both ovarian follicles and testicular tubular elements. Ovotesticular disorder of sexual development occurs in fewer than 10% of all disorders of sexual development. Gonadal tumors with malignant potential occur in 2.6% of all cases of ovotesticular disorder of sexual development...

Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting women of reproductive age manifesting with polycystic ovaries, menstrual irregularities, hyperandrogenism, hirsutism, and insulin resistance. The oligomenorrhea and amenorrhea characteristic to PCOS are associated with low bone mineral density (BMD); conversely, the hyperandrogenism and hyperinsulinemia may elicit a protective effect on BMD. As bone geometric properties provide additional information about bone strength, the objective of this study was to compare measures of hip geometry in women with PCOS to a healthy female population...

Individuals under chronic psychological stress can be difficult to identify clinically. There is often no outwardly visible phenotype. Chronic stress of sufficient magnitude not only impacts reproductive function, but also concomitantly elicits a constellation of neuroendocrine changes that may accelerate aging in general and brain aging in particular. Functional hypothalamic amenorrhea, a phenotypically recognizable form of stress, is due to stress-induced suppression of endogenous gonadotropin-releasing hormone secretion...

Androgen excess in women is associated with metabolic dysfunction (obesity, hyperinsulinemia, insulin resistance, and increased risk of type 2 diabetes (T2D)) and reproductive dysfunction (polycystic ovaries, amenorrhea, dysregulated gonadotropin release, and infertility). We sought to identify the effects of androgen excess on glucose metabolic dysfunction and the specific mechanisms of action by which androgens are inducing pathology. We developed a mouse model that displayed pathophysiological serum androgen levels with normal body mass/composition to ensure that the phenotypes were directly from androgens and not an indirect consequence of obesity...
