OBJECTIVE The aim of the study was to evaluate the safety and efficacy of vaginal estradiol (E2) softgel capsules for moderate-to-severe symptoms of vulvar and vaginal atrophy (VVA). Previous phase 1 studies showed lower systemic estrogen concentrations with this softgel capsule compared with an approved low-dose vaginal E2 tablet. METHODS In this randomized, double-blind, placebo-controlled ...

Background: To determine the frequency of bacterial vaginosis in female patients with complaint of vaginal discharge and to evaluate the accuracy of Amsel’s clinical criteria taking Nugent criteria as gold standard. Methods: In this descriptive study female patients of a reproductive age group presenting with a complaint of abnormal vaginal discharge were included. A routine gynaecological spec...

Understanding the host immune response to vaginal exposure to RNA viruses is required to combat sexual transmission of this class of pathogens. In this study, using lymphocytic choriomeningitis virus (LCMV) and Zika virus (ZIKV) in wild-type mice, we show that these viruses replicate in the vaginal mucosa with minimal induction of antiviral interferon and inflammatory response, causing dampened...

The involution of the female genital tract seems to reflect a built-in biological life expectancy, inter-related with the hypothalamic-hypophyseal-ovarian axis. Lower levels of oestradiol have a number of adverse effects, including on the lower urinary tract. The major universal change is vaginal atrophy. The vaginal mucosa becomes thinner and dry, which can produce vaginal discomfort, dryness,...

The kisspeptin/Gpr54 signaling pathway plays a critical role in reproduction by stimulating the secretion of GnRH, yet mice carrying mutations in Kiss1 (which encodes kisspeptin) or Gpr54 exhibit partial sexual maturation. For instance, a proportion of female Kiss1−/− and Gpr54−/− mice exhibit vaginal oestrus, and some male Kiss1−/− and Gpr54−/− mice exhibit spermatogenesis. To characterise thi...
