LH releasing hormone

The synthesis and release of both FSH and LH from the pituitary is stimulated by a hypothalamic peptide, gonadotrophin-releasing hormone (also known as gonadorelin, LH-releasing hormone, or LH/FSH-releasing factor). [Pg.313]

Progesterone produces direct membrane effects [16]. These include actions that promote maturation of spermatozoa as well as oocytes and facilitation of the release of neurotransmitters such as dopamine and LH-releasing hormone (LHRH) (Fig. 52-7). Membrane actions of progesterone also activate oxytocin receptors in the hypothalamus in a way that enables oxytocin to turn on sexual behavior in the estrogen-primed female rat [3],... [Pg.853]

All the stimulating primer effects in mammals analyzed so far share a common hormonal pathway the first measurable event is stimulation of LH-releasing hormone (LHRH) release. This, in turn, stimulates LH levels and leads to increases of estrogens in females and testosterone in males. In females, changes in size and function of uterus and ovaries follow, while males respond... [Pg.218]

LH-releasing hormone, indicating normal gonadotropin production, storage, and release. The clomiphene-stimulated rise in FSH does not increase estrogen levels, further confirming primary ovarian dysfunction (L12). Fertility is restored after renal transplantation, and several hundred women with renal allografts have borne normal babies. [Pg.93]
