Fertirelin is a synthetic luteinizing hormone-releasing hormone (LH-RH) analogue, and it is a potent LHRH agonist. After a transient increase, continuous administration results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.
Fertirelin was administered at the beginning of the protocol followed 7 days later by 500 μ G cloprosterol. Two days later, a second dose of fertirelin was given and AI performed 16-19 h later regardless of the incidence of behavioral oestrus. The conception rate did not differ between the 50 μ G fertirelin group (61.1%; N = 72) and the 100 μ G group.
Mainly has a strong angiotensin II vasoconstriction and increase in blood pressure. The mechanism is: 1. So that the body arteriole smooth muscle contraction, increased peripheral resistance; 2. So increase the release of adrenal aldosterone, causing sodium retention, increased blood volume; 3. Directly contribute to renal tubular sodium and water reabsorption; 4. So the brain central nervous sympathetic vasoconstrictor activity, causing increased peripheral vascular resistance; 5. Stimulate the adrenal medulla to release epinephrine and norepinephrine.
