BACKGROUND Human reproduction depends on an intact hypothalamic–pituitary–gonadal
(HPG) axis. Hypothalamic gonadotrophin-releasing hormone (GnRH) has been recognized …

Puberty is the attainment of fertility, a process encompassing morphological, physiological
and behavioural development. The increased hypothalamic secretion of the gonadotrophin …

Fertility in mammals is controlled by hypothalamic neurons that secrete gonadotropin-
releasing hormone (GnRH). These neurons differentiate in the olfactory placodes during …

Behavioral interactions among social animals can regulate both reproductive behavior and
fertility. A prime example of socially regulated reproduction occurs in the cichlid fish …

Gonadotropin-releasing hormone (GnRH) is the neuropeptide that links the brain to the
reproductive system. Most vertebrate species express two forms of GnRH, which differ in …

Gonadotropin-releasing hormone (GnRH) cells are the key regulators of reproductive
function in all vertebrate organisms. The GnRH molecule is synthesized in a small number of …

The “ovarian cycle” is an exquisite and dynamic endocrine system that includes ovarian
events, hypothalamic–pituitary interactions, uterine endometrial and myometrial changes …

Geoffrey Wingfield Harris' demonstration of hypothalamic hormones regulating pituitary
function led to their structural identification and therapeutic utilization in a wide spectrum of …

Comprehensive studies have provided a clear understanding of the effects of gonadal
steroids on the secretion of gonadotropin releasing hormone (GnRH), but some inconsistent …

Reproduction in mammals is controlled by interactions between the hypothalamus, anterior
pituitary and gonads. Interaction of GnRH with its cognate receptor is essential to regulating …
