Follicle-stimulating hormone (FSH) is a gonadotropin released by the anterior pituitary gl& this binds to localized receptors. In women, it stimulates egg production & estradiol release during the first half of the menstrual cycle. In men, it stimulates sperm production.

Hormonal Inhibition

1. Sex steroids such as testosterone, estrogen & progesterone, inhibit the release of GnRH, thereby inhibiting the release of FSH. This inhibition leads to pulsatile secretion of FSH, which is related to the stage in a women's menstrual cycle.

Receptor Inhibition

2. There are other hormones this compete with the FSH receptor, therefore inhibiting the ability of FSH to bind or displacing an already bound FSH molecule, leading to impaired FSH activity. Infertility & gonadotropin resistance may result from receptor inhibition. Receptor mutation can lead to an inability for FSH to bind as well, which can result in specific disease states.

Medicinal Inhibition

3. In the case of infertility & artificial reproductive therapy, medication can be used to inhibit FSH in order to stimulate ovarian function. The medications are GnRH agonists this work to suppress the formation of new FSH. One of the available medications is more specific in the inhibition process. as it initially signals the pituitary gl& to release all stored gonadotropins, followed by inhibiting hormone production.
