What are the functions of Gonadotropins?

Gonadotropins are of two types Follicle Stimulating hormone (FSH) and Luteinizing hormone (LH)The main function of FSH in females is to stimu­late the development and maturation of ovarian follicles up to the stage of ovulation.

In males FSH stimulates the process of spermatogenesis in­cluding sperm formation. FSH is also known as Gametokinetic factor as it has influence on both male and female gametes. Luteinizing hormone has the following functions.

1. It causes ovulation (release of mature ovum from the ovary) and helps in the formation of corpus lutem working along with FSH. The corpus lutem inturn secrets progesterone in women which is essential for the continuation of the pregnancy.


2. In males LH is generally known as ICSH. This stimulates the intersti­tial cells(cells of Leydig)of testis to secrete the male sex hormone – test­osterone. Testosterone is also necessary for the maintenance of secondary sexual characters.
