Reproduction is controlled by the hypothalamic-pituitary-gonadal (HPG) axis. Gonadotropin-
releasing hormone (GnRH) neurons play a central role in this axis through production of …

Neurohormones similar to those of mammals are carried in fish by hypothalamic nerve fibers
to regulate directly follicle-stimulating hormone (FSH) and luteinizing hormone (LH) …

Gonadotropin-releasing hormone (GnRH) is the first key hormone of reproduction. GnRH
analogs are extensively used in in vitro fertilization, and treatment of sex hormone …

Although estrogen is known to activate endothelial nitric oxide synthase (eNOS) in the
vascular endothelium, the molecular mechanism responsible for this effect remains to be …

In human beings, two forms of GnRH, termed GnRH-I and GnRH-II, encoded by separate
genes have been identified. Although these hormones share comparable cDNA and …

The crucial role of pituitary GnRH receptors (GnRH-R) in the control of reproductive
functions is well established. These receptors are the target of GnRH agonists (through …

The precise interplay of hormonal influences that governs gonadotropin hormone production
by the pituitary includes endocrine, paracrine and autocrine actions of hypothalamic …

The hypothalamic gonadotropin-releasing hormone (GnRH) is a key regulator of the
reproductive system, triggering the synthesis and release of LH and FSH in the pituitary …

Reproductive function in mammals is regulated by the pituitary gonadotropins luteinizing
hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH are secreted by the …

Gonadotropin-releasing hormone (GnRH) is the primary regulator of mammalian
reproductive function in both males and females. It acts via G-protein coupled receptors on …
