Coital activation of the hypothalamo-hypophyseal ovarian axis (HOA) is well documented in rabbits, but coital excitation of the hypothalamo-hypophyseal testicular axis (HTA) is less well described. We and others have postulated that the response of t

In the female rabbit, coitus induces a massive release of hypothalamic gonadotropin-releasing hormone (GnRH) within 20 min. The GnRH surge is preceded by an increase in hypothalamic norepinephrine (NE) release. Presumably, coitus stimulates NE, hence

Noradrenaline plays a key role in the initiation of ovulation in nonprimate species. A similar noradrenaline role in the primate has not been established experimentally. We utilized the ovariectomized-oestrogen-supplemented (OVX + E) rhesus macaque t

Leptin acts as a metabolic activator of the neuroendocrine reproductive axis in several rodent species, but whether leptin plays a similar role in primates is unknown. To explore this question, we examined the effects of leptin on gonadotropin and te

Gonadotropin-releasing hormone (GnRH) is a key hypothalamic peptide that controls the secretion of pituitary gonadotropins, particularly luteinizing hormone (LH), and hence gonadal function. Hypothalamic GnRH is released in a pulsatile manner. In the

Pulsatile secretion of hypothalamic gonadotropin-releasing hormone (GnRH) is suppressed by alpha-adrenergic antagonists in ovariectomized (OVX) rabbits, thus suggesting that initiation of GnRH pulses requires the presence of norepinephrine (NE) stimu

Certain brain peptides and catecholamines function in activating the hypothalamohypophysial-ovarian axis in both rabbits and rhesus monkeys. The natural stimulus for a surge release of GnRH is coitus in rabbits, whereas the initial excitatory signal

Concomitant fluctuations in median eminence perfusate GnRH and plasma LH occur in rhesus macaques during the periovulatory period and after ovariectomy. The association between GnRH and LH pulses during the follicular and luteal phases of the monkey

Substance P (SP) is present in large quantities in the brainstem and hypophysiotropic areas of the brain, but its roles in gonadotropin and prolactin secretion are controversial. The aim of this study was to measure luteinizing hormone (LH), follicle
