Assessing new peptides that may be involved in the physiological regulation of the gonadal axis in humans: gonadotropin inhibitory hormone

Abstract

The hypothalamo-pituitary-testicular (HPT) and hypothalamo-pituitary-ovarian (HPO) axes are integrated networks that regulate androgenization or estrogenization (including embryonic, infantile, pubertal and adult sexual maturation), male or female sexual behavior, and spermatogenesis or ovulation, respectively. Dysregulation of the HPT axis, for example, results in pubertal delay, eunuchism, impaired spermatogenesis, and reduced systemic androgen exposure; and may also contribute to some of the features of male aging, impair recovery from protracted critical illness, and induce visceral adiposity, sarcopenia, osteopenia, and insulin resistance. Furthering knowledge of how the gonadal axes are regulated will thereby inform important and diverse pathophysiological processes.
