Fertirelin is a GnRH and LH-RH analogue; it also becomes the treatment choice for reversing cow follicular cysts.

Fertirelin, an analog of GnRH 2.5 to 10 times more potent than native GnRH , has become the treatment of choice for reversing follicular cysts^[1]. Administration of high doses of Fertirelin is found to reduce superovulatory responses^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Mice^[2]
Nulliparious female mice weighed 25-28 g (8-9 weeks) are used throughout the study. The mice are ddY strain and specific pathohen-free. As ovulation can be induced in mice at any time with administration of human chorionic gonadotrophin (hCG), 5.0 IU of hCG is injected subcutaneously into each mouse at 17:00, irrespective of the stage of the estrus cycle. This day is designated as Day 0. Nine groups are established according to the dose of Fertirelin ranging from 0.001 to 1.0 μg, and the administration are carried out at 22:00 on Day 0 and at 2:00, 6:00, 10:00 and 14:00 on Day 1^[2].
