Effects of FSH on a Woman’s Fertility

Follicle Stimulating Hormone which is popularly called FSH can directly affect a woman’s menstrual cycle, her ovulation, and therefore, her chances to conceive.

When a woman’s FSH levels are very low, as perhaps observed in women who have PCOS (Polycystic Ovarian Syndrome), or very high (as perhaps observed in women who experience premature menopause), it can make a woman’s ability to get pregnant complicated.

The FSH level which is considered “normal” for a woman who hopes to conceive is below 10 mIU/ml typically. The FSH level a woman’s body produces has a direct correlation with her ovarian reserve, that is, the quantity and quality of her remaining eggs. Consequently, the knowledge of a woman’s FSH level can be a useful measure of how fertile she is.

When the quantity and quality of her egg starts reducing, a woman’s body attempts to make up for the reduction by increasing the quantity of the FSH it produces in its attempt to try and to stimulate the function of the ovaries. Hence, higher FSH levels may be an inference for an approaching menopause. Low FSH levels in addition have impact on fertility and therefore can cease a woman’s reproductive cycles. You can now see that a woman’s fertility status has a close relationship with her FSH levels.

It’s easy for you to test your FSH levels in the comfort of your home or when you visit the clinic. You can purchase FSH tests from These tests are designed for home use and detect at least 25 mIU/mL FSH level. You must perform these tests starting on the third day of your menstrual bleeding and proceed until the 5th day. If your FSH test is positive at home, you are advised to see your doctor so that you can get further blood test. The blood test is carried out again simultaneously with the urine test, starting on day 3 of your cycle.

Luckily, effective and natural approaches exist that can be used to help reduce the effects of rising FSH levels on fertility. Vitex, an important constituent in FertilAid for Women, has been proven in tests carried out in the clinics to have the ability to suppress the release of FSH. Most tested women experienced either no increase at all or experienced a moderate decrease in their FSH levels throughout the six months of study.
