Function
Anti-Mullerian Hormone (AMH) is a protein hormone produced by the granulosa cells within the ovarian follicles. Its primary role in adult women is to serve as a marker for ovarian reserve—the remaining egg supply. Unlike FSH, AMH levels remain relatively stable throughout the menstrual cycle, making it a convenient and reliable marker for fertility assessment.
Why it is Ordered
AMH testing is most frequently used in the context of assisted reproductive technology (ART), such as Invitro Fertilization (IVF). It helps predict how a woman will respond to ovarian stimulation medication. It is also used to assess the onset of menopause or to evaluate conditions like Polycystic Ovary Syndrome (PCOS), where follicle counts are abnormally high.
Associated Conditions
- Ovarian Reserve Depletion: Low AMH indicates a declining egg count, which is natural with age but concerning if premature.
- PCOS: Characterized by very high AMH levels due to the abundance of small antral follicles.
- Ovarian Cancer: Certain types of ovarian tumors (granulosa cell tumors) secrete AMH, making it a useful tumor marker for monitoring recurrence.
- Primary Ovarian Insufficiency: Very low or undetectable AMH in women under 40.

Why Context Matters
AMH levels can be temporarily suppressed by hormonal contraceptives (birth control pills). Furthermore, Vitamin D deficiency has been linked to lower AMH levels, and different laboratory platforms (e.g., Roche vs. Beckman Coulter) can produce slightly different numerical results for the same sample, requiring standardized interpretation.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
