Introduction:

The pituitary gland's follicle-stimulating hormone (FSH) plays an important role in egg production and release.

Follicle-stimulating hormones (FSH) are known as gonadotropins because they stimulate the gonads and regulate both male and female sexual and reproductive characteristics.

FUNCTIONS OF FSH:

• It initiates follicular growth.

• It controls the menstrual cycle.

• It also increases oestradiol production.

• It stimulates the ovary to produce an egg.

• It regulates the development, growth, development of secondary sexual characteristics and reproductive processes.

• This hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation.
