What does follicle stimulating hormone do?

Follicle Stimulating Hormone (FSH) is a hormone produced by the pituitary gland in the brain. Here's what it does, step by step:

1. FSH is released by the pituitary gland, which is located at the base of the brain.

2. Once released, FSH travels through the bloodstream to the ovaries in females and the testes in males.

3. In females, FSH stimulates the growth of ovarian follicles, which are the small sacs in the ovaries that contain the eggs. This is a crucial part of the menstrual cycle. As the follicles mature, they release another hormone called estrogen.

4. In males, FSH stimulates the production of sperm. It works alongside another hormone called luteinizing hormone to support the production and maturation of sperm cells.

5. FSH levels in the body can fluctuate depending on the time of the menstrual cycle in females, and can be influenced by factors such as age and overall health.

In summary, FSH plays a crucial role in human reproduction by regulating the growth and maturation of eggs in females and the production of sperm in males.

Follicle Stimulating Hormone (FSH) is a type of gonadotropin hormone that is key for reproduction. It is secreted by the pituitary gland, a small gland located at the base of the brain.

Here's what it does, step by step:

1. In females, FSH stimulates the growth and maturation of ovarian follicles (small sacs in the ovaries that contain immature eggs). This is the first step in the menstrual cycle.

2. As the follicles mature, they begin to secrete estrogen, which triggers a decrease in FSH production. This is a feedback mechanism to ensure that not too many follicles mature at once.

3. Once the level of FSH decreases, usually one follicle continues to mature while the others stop growing and eventually degenerate. The mature follicle then releases an egg during ovulation.

4. In males, FSH stimulates the production of sperm in the testes. It acts on the Sertoli cells, which support and nourish the developing sperm cells.

So, in summary, FSH plays a crucial role in human reproduction by regulating the development, growth, pubertal maturation, and reproductive processes of the body.
