What is Anti-Müllerian Hormone (AMH) and why is it important?
AMH is produced by ovarian follicles. Measuring AMH helps estimate ovarian reserve, guide fertility planning, and support evaluation of conditions like PCOS and premature ovarian insufficiency.
Who should consider AMH testing?
- People planning for pregnancy or fertility treatment
- Those monitoring reproductive aging or approaching menopause
- Individuals with irregular cycles or possible PCOS
- Anyone considering fertility preservation (e.g., egg freezing)
What conditions can AMH levels help evaluate?
AMH testing can provide insight into:
- Ovarian reserve and fertility potential
- Polycystic ovary syndrome (PCOS)
- Premature ovarian insufficiency (POI)
- Response to fertility treatments such as IVF
Providers may also use AMH in the context of menopausal transition and long-term reproductive health planning.
How are results used by providers?
Providers use AMH to guide conversations about fertility potential and timing, support diagnosis of certain reproductive conditions, and help plan treatments such as IVF. Results are reviewed in the context of other hormone levels for a comprehensive view.
How does AMH testing benefit patients directly?
Patients gain clear, actionable insights into reproductive health that can guide decisions around family planning, fertility treatment, or long-term health strategies.
What factors can influence AMH levels?
AMH levels can be affected by health and lifestyle factors. Conditions like PCOS or higher estrogen can raise AMH, while vitamin D deficiency, smoking, untreated thyroid conditions, and chronic stress can lower it. Endocrine disruptors and inflammation may also play a role.
Does AMH need to be collected on a specific day of the cycle?
Unlike many other reproductive hormones, AMH is cycle-independent, meaning it can be tested at any point during the menstrual cycle.
Does oral contraceptive use affect AMH test results?
Yes. Oral contraceptives tend to lower measured AMH levels, which may not reflect the patient's baseline ovarian reserve.
