Abstract Polycystic Ovarian Syndrome (PCOS) is a disease that characterized by an increased Gonadotropin-Releasing-Hormone (GnRH) pulsatile frequency, causing altered LH/FSH ratio. More precisely Luteinizing Hormone (LH) secretion compared to decreased Follicle-Stimulating (FSH) leads the development of hyperandrogenism and low-level concentration estrogens therefore negative estrogenic feedbac...

In contrast to the human lutropin receptor (hLHR), very few naturally occurring activating mutations of the structurally related human follitropin receptor (hFSHR) have been identified. The present study was undertaken to determine if one aspect underlying this discrepancy might be a general resistance of the hFSHR to mutation-induced constitutive activity. Five different mutations were introdu...

BACKGROUND Ovarian cysts are a common cause for gynecological surgery. However, some cysts are a direct result of endocrine disorders and do not require surgery. This report describes an unusual case in which persistent ovarian cysts are associated with primary hypothyroidism in a young woman. The data were collected by history-taking, physical examination, laboratory tests, ultrasound, magneti...

A single i.p. injection of vincristine (1000 microgram/kg) into rats increased the plasma concentration of corticosterone after a latent period of 4 hr; the effect lasted for 48 hr. The response was dose related with the threshold dose being 100 microgram/kg and the maximal effect occurring after 250 microgram/kg. Vincristine also increased plasma corticosterone levels in hypophysectomized rats...
