Previous small animal models for menopausal transition are mainly performed to mimic the biochemical changes of patients with menopausal transition. The psychological symptoms in animal models are often overlooked. To mimic clinical situation, we developed a new mouse model of menopausal transition: the combination of bilateral ovariectomy (OVX) and empty bottle stimulation (EBS). After OVX and 21 days of EBS, behavioral test and pentobarbital-induced sleep test were carried out. Then all the animals were euthanized for further investigations...

S100 calcium-binding protein A6 (S100A6) is up-regulated in many malignancies and overexpression of S100A6 has been identified associated with proliferation, migration and invasion phenotype in several cancer cells. In the present study, we explored whether S100A6 plays a role in the development of endometriosis. Significantly higher levels of mRNA and protein expression of S100A6 were observed in ectopic endometrial tissues compared to eutopic and normal endometrial tissues. Silencing of S100A6 in ectopic endometrial stromal cells (ESCs) significantly inhibited cell viability, migration and invasion...

Polycystic ovarian syndrome (PCOS) is a common endocrinologic disorder in women of reproductive age characterized by polycystic ovaries, oligo/anovulation, and hyperandrogenism. Not only anovulation but also endometrial dysfunction can reduce fertility in PCOS patients. Wnt pathway is responsible for endometrial proliferation which be strongly regulated by estradiol. To determine the effects of clomiphene citrate (CC) and letrozole, we measured the expression of some main ligands of Wnt/β-catenin signaling including Wnt7a, Wnt3, and Wnt8b in the endometrial samples taken from PCOS women on day 12 of the menses who received 100 mg CC or 5 mg letrozole as well as from women without treatment...

This concise report deals with the known effects of progestogen lack in early pregnancy with failure of implantation and blood supply to the placenta depending on proper trophoblast invasion, spiral artery remodeling, and vessel dilatation. The pathophysiology of preeclampsia will be outlined and the most recent data on the effect of dydrogesterone presented. Dydrogesterone appears to be able to reduce significantly the development of preeclampsia. The effect is related to begin with such prevention and this should be continued until 37th weeks of gestation which would also mean prevention of premature labor...

Platelets modulate clinically relevant yet incompletely understood tissue regeneration processes, and platelet rich plasma (PRP) has been previously used with some success in various non-reproductive medical contexts. Here, we extended PRP application to ovarian tissue with a view to document impact on ovarian reserve among women attending for infertility treatment. PRP was freshly isolated from patients (n= 4) with diminished ovarian reserve as determined by at least one prior IVF cycle canceled for poor follicular recruitment response or estimated by serum AMH and/or FSH, no menses for ≥1 year...

The impacts of gonadtropin-releasing hormone (GnRH) agonists on thyroid function have long been observed and the conclusions were controversial. We here reported three cases of transient hyperthyroidisms after triptorelin therapy. The three patients showed decreased thyroid-stimulating hormone (TSH), with or without elevated free triiodothyronine (FT3) and free thyroxine (FT4) 2 weeks after injection of triptorelin. Thyroid-specific autoantibody assays showed antithyroid microsome autoantibody (TMAb) and (or) antithyroglobulin autoantibody (TgAb) were positive in two patients while and antithyrotropin receptor autoantibody (TRAb) were negative in all three cases...

The aim of this article was to explore the link between postmenopausal status according to years since menopause (YSM) and the prevalence of metabolic syndrome (MetS). This survey was conducted from January 2012 to August 2013. A total of 6022 women (3511, 58.3% were post-menopause) from Rural Northeast China were randomly selected and examined. The prevalence of the MetS was significantly higher in postmenopausal women (Post-MW) than in premenopausal women (Pre-MW) (55.0% vs. 33.1%, p .001). The risk for MetS in Post-MW increased with the number of YSM, reaching the peak level in the 5- to 9-year group (OR, 1...

Congenital adrenal hyperplasia (CAH) is an inherited disorder of adrenal steroidogenesis often diagnosed in infancy. Gynecologists may encounter adult patients with CAH due to the clinical effects of increased androgens, e.g. hirsutism, clitoromegaly, oligomenorrhea, or, rarely, pelvic masses. This case report reviews the association of para-ovarian adrenal rest tumors with CAH, and the role of gynecologists in their evaluation and treatment. A 23-year-old woman with CAH (21-hydroxyase deficiency) untreated for the past 5 years presented with a pelvic mass and elevated serum testosterone (1433 ng/dL) and plasma ACTH (1117 pg/mL)...
