Follicle-stimulating hormone (FSH) is a hormone produced by the pituitary gland. The FSH test measures the level of FSH in the blood.
In women, FSH plays a role in the menstrual cycle and the production of eggs. The FSH test is often used to assess fertility and to help diagnose fertility problems.
During fertility treatment, the FSH test is often used to assess ovarian reserve, which is a measure of the number of eggs that a woman has remaining in her ovaries. A high level of FSH may indicate a lower ovarian reserve and potentially lower fertility, while a normal or low level of FSH may indicate a higher ovarian reserve and potentially higher fertility.
The FSH test is usually done with a blood test. It is a simple and non-invasive test that can be done at any time in the menstrual cycle. The results of the FSH test can be used in combination with other tests and evaluations to assess ovarian reserve and fertility.
