What is Gonadorelin ?
Gonadorelin is another name for gonadotropin-releasing hormone (GnRH). It is a synthetic decapeptide prepared using solid phase peptide synthesis. GnRH is responsible for the release of follicle stimulating hormone and leutinizing hormone from the anterior pitutitary.
GnRH is available as gonadorelin hydrochloride )and gonadorelin diacetate tetrahydrate for injectable use. Studies have described it being used via an infusion pump system to induce ovulation in patients with hypothalamic hypogonadism. It is also used in veterinary medicine as a treatment for cattle with
cystic ovarian disease.
Gonadorelin is used to test how well the hypothalamus and the pituitary glands are working. It is also
used to cause ovulation (release of an egg from the ovary) in women who do not have regular ovulation and menstrual periods because the hypothalamus gland does not release enough GnRH.
Gonadorelin is responsible for the release of follicle stimulating hormone and leutinizing hormone from
the anterior pitutitary. In the pituitary GnRH stimulates synthesis and release of FSH and LH, a process
that is controlled by the frequency and amplitude of GnRH pulses, as well as the feedback of androgens and estrogens.
The pulsatility of GnRH secretion has been seen in all vertebrates, and it is necessary to ensure a
correct reproductive function. Thus a single hormone, GnRH, controls a complex process of follicular
growth, ovulation, and corpus luteum maintenance in the female, and spermatogenesis in the male. Its
short half life requires infusion pumps for its clinical use.
