The aim of the present study was to compare the effects of full-length rat kisspeptin (rKp-52) with C-terminal decapeptide (Kp-10) of rat or human kisspeptin on LH release in intact male rats. Plasma LH profiles were determined by frequent blood samp

Melatonin (MLT) has a significant role in mammalian reproduction, with little or no effect in birds. In the present study we studied the role of MLT in regulation of luteinizing hormone (LH) secretion in castrated White Leghorn (WL) roosters. In Expe

This study explores changes in pituitary pulsatile Luteinizing Hormone (LH) secretion in intact and castrated male mink, either previously photogonadostimulated by short day treatment (LD 4:20), or maintained in a state of sexual quiescence by long d

Hyperandrogenism and ovulatory dysfunction are common in women with either polycystic ovary (PCOS) or ovarian virilizing tumor. However, contrasting with the numerous studies that have extensively described gonadotropin secretory abnormalities, princ

The OAAD method was used to estimate LH levels in plasma and adenohypophyses of castrated and intact White Leghorn cockerels as related to age. Hypophysial LH concentration in intact males rose steadily and significantly with increasing age, but decr
