Testosterone has been reported to cause a decrease in uterine fluid volume in which this could involve the aquaporins (AQPs). This study aimed to investigate effect of testosterone on uterine AQP-1, 5, and 7 expressions in order to explain the reported reduction in uterine fluid volume under testosterone influence. Ovariectomized adult female rats...
Article
Unlabelled: Pinopode, a progesterone-dependent endometrial projection which appears during uterine receptivity period, participates in blastocyst implantation. Blastocyst loosely attaches to pinopode via L-selectin ligand (MECA-79). We hypothesized that pinopode and MECA-79 expressions were affected by testosterone. Therefore, the effect of testos...

Introduction: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder amongst reproductive-age women, and 61% to 76% of women with PCOS are obese. Obese women with PCOS are usually burdened with infertility problems due to implantation failure. Thus, progesterone treatment is usually used to improve implantation rates. Although Hb-EGF exp...

Polycystic ovary syndrome (PCOS) and endometriosis are reproductive disorders that may cause infertility. The pathology of both diseases has been suggested to be associated with sex steroid hormone receptors, including oestrogen receptors (ER), progesterone receptors (PRs) and androgen receptors (ARs). Therefore, with this review, we aim to provide...
