Follicle Stimulating Hormone

What is Follicle stimulating hormone?

Follicle stimulating hormone (FSH or follitropin) is a sex hormone produced naturally in the pituitary gland under the brain. It acts with luteinising hormone to stimulate the production of eggs in women (ovulation) and sperm in men.  The level of FSH in blood can be measured.

Normal levels of follicle stimulating hormone:

The normal ranges are:-

Before puberty 0 to 3 IU/L.
Adult female 1 to 9 IU/L.
Female at ovulation 10 to 30 IU/L.
After menopause 40 to 200 IU/L.
Adult male 1 to 5 IU/L.

Causes of imbalanced follicle stimulating hormone:

A low level in the blood may be due to Stein-Leventhal syndrome and may be a cause of infertility. A very high level may be due to disease or failure of the testes or ovaries. Levels normally rise at mid-cycle in ovulating women.

It may be used as an injectable medication to treat female and male infertility.

Side effects of follicle stimulating hormone:

Common side effects include nausea, diarrhoea and headache, while less common ones may include multiple pregnancies, breast tenderness and/or enlargement, acne and weight gain.
