AMH: Accurate Fertility Predictor for Women

AMH testing is the most accurate predictor of a woman’s ovarian reserve, surpassing FSH levels in identifying diminished egg supplies. A simple blood test, AMH remains consistent across the menstrual cycle and helps physicians tailor fertility treatments like IVF or egg freezing. Studies show AMH levels decline with age, becoming undetectable at menopause, and correlate with PCOS severity.

Key Takeaways

AMH Blood Test for Ovarian Reserve Assessment

AMH measures the number of immature follicles in the ovaries, providing an early indicator of declining fertility. Unlike FSH, AMH remains stable throughout the menstrual cycle, making it reliable for testing at any time. Lower AMH levels signal reduced ovarian reserve, prompting discussions about fertility preservation options like egg freezing.

AMH Levels and Menopause Prediction

Research links declining AMH levels to approaching menopause, as levels become undetectable post-menopause. This makes AMH a critical tool for predicting reproductive lifespan. Women with consistently low AMH may face earlier menopause, influencing family planning timelines.

AMH Testing During Contraceptive Use

Continuous combined contraceptives (pills, patches, or vaginal rings) lower AMH levels. For accurate results, AMH testing should occur on day 3 of the menstrual cycle. Physicians must account for contraceptive type to avoid misinterpreting AMH as a false low.

AMH and PCOS Correlation

Women with polycystic ovary syndrome (PCOS) typically have elevated AMH levels due to increased early antral follicles. High AMH in PCOS patients correlates with insulin resistance severity, aiding in diagnosis and treatment decisions for fertility challenges.

AMH in Fertility Treatment Protocols

AMH guides personalized fertility treatment plans by predicting responses to stimulation drugs. High AMH levels indicate a risk of over-response, while low levels suggest potential under-response. This data helps adjust medication dosages to optimize outcomes for IVF or IUI.
