Don’t obtain follicle-stimulating hormone (FSH) levels in women in their 40s to identify the menopausal transition as a cause of irregular or abnormal menstrual bleeding.
Menstrual bleeding patterns for women after age 40 are less predictable than in the younger years due to the normal menopausal transition. Menopause is defined as the absence of menstrual periods for one year when no other cause can be identified (it is often accompanied by symptoms such as hot flashes and night sweats). During this time, blood levels of FSH vary both from woman to woman and from day to day in the same woman. An FSH level does not predict when the transition to menopause will occur, diagnose that it has begun or provide reassurance that contraception is no longer necessary. If there are no other causes of irregular or abnormal bleeding, the treatment for these women will not change based on the FSH level.

The Practice Committee of the American Society for Reproductive Medicine (ASRM) reviewed evidence from ASRM’s practice documents to identify possible topics along with suggestions for possible topics from the ASRM Board of Directors. By consensus, the Practice Committee narrowed the list to the top five most overused tests within specified parameters. Additional input was sought from the ASRM Board of Directors and incorporated. The final list was reviewed and approved by the ASRM Board of Directors. The ASRM Board of Directors and Practice Committee are comprised of representatives from every aspect of reproductive medicine through our five affiliated societies including the Society for Assisted Reproductive Technology, the Society of Reproductive Surgeons, the Society for Reproductive Endocrinology and Infertility, the Society for Male Reproduction and Urology and the Society of Reproductive Biologists and Technologists.
