Get tested with Superpower

If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.

Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.

With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.

Key benefits of AMH (anti-Müllerian hormone) testing

• Reveals your ovarian reserve and how many eggs remain available for fertility.
• Guides timing for family planning or egg freezing based on your biology.
• Flags early menopause risk so you can plan ahead with your doctor.
• Clarifies irregular periods by identifying polycystic ovary syndrome (PCOS) when elevated.
• Supports fertility treatment decisions by predicting response to ovarian stimulation.
• Tracks ovarian function over time to monitor age-related or treatment-related changes.
• Best interpreted alongside FSH, estradiol, and your menstrual pattern for full context.

What is AMH (anti-Müllerian hormone)?

A hormone that guards the ovarian reserve

AMH is a protein hormone produced by the small follicles in a woman's ovaries. These follicles are tiny fluid-filled sacs, each containing an immature egg. The granulosa cells lining these early-stage follicles secrete AMH into the bloodstream throughout a woman's reproductive years.

It reflects how many eggs remain

AMH levels mirror the size of the ovarian reserve, the pool of eggs still available for potential ovulation. Unlike hormones that fluctuate with the menstrual cycle, AMH remains relatively stable from day to day. This makes it a reliable snapshot of ovarian function and reproductive potential at any given time.

Originally named for its role in male development

The hormone gets its name from the Müllerian ducts, embryonic structures that develop into the uterus and fallopian tubes in females. In male fetuses, AMH produced by the testes causes these ducts to regress. In adult women, however, AMH serves an entirely different purpose as a marker of fertility and ovarian aging.

Why is AMH (anti-Müllerian hormone) important?

AMH is a hormone produced by the ovaries in women and the testes in men that serves as a direct window into reproductive potential and certain endocrine disorders. In women of reproductive age, it reflects the number of remaining eggs in the ovarian reserve, making it a key marker for fertility assessment and timing. In men and children, AMH helps evaluate testicular function and sexual development.

It reveals your ovarian reserve and fertility window

In women, AMH levels naturally decline with age as the egg supply diminishes. Low or undetectable levels suggest a reduced ovarian reserve, often seen in women approaching menopause, those with premature ovarian insufficiency, or after chemotherapy. This can mean shorter fertile years, irregular cycles, and difficulty conceiving. Very low AMH may also signal accelerated reproductive aging.

Elevated levels point to hormonal imbalance

High AMH is most commonly associated with polycystic ovary syndrome (PCOS), where numerous small follicles produce excess hormone. Women may experience irregular periods, acne, weight gain, and insulin resistance. Elevated AMH can also predict ovarian hyperstimulation during fertility treatments.

It connects reproduction to metabolic and long-term health

AMH ties ovarian function to broader metabolic and cardiovascular health, especially in PCOS. It also helps diagnose disorders of sexual development in children and monitor testicular tumors in men. Understanding AMH offers insight into reproductive lifespan, hormonal balance, and systemic well-being.

What do my AMH (anti-Müllerian hormone) results mean?

Low AMH levels

Low values usually reflect a reduced number of remaining egg-containing follicles in the ovaries, known as diminished ovarian reserve. This is a natural part of aging and typically becomes more pronounced after age 35. In younger women, low AMH may signal premature ovarian aging or primary ovarian insufficiency. Low AMH is associated with reduced fertility potential and a shorter window until menopause. In men, AMH is normally low after puberty, so interpretation differs by sex and developmental stage.

Optimal AMH levels

Being in range suggests a healthy ovarian reserve consistent with your age and reproductive stage. In women of reproductive age, this reflects an adequate pool of developing follicles and normal ovarian function. Optimal values vary widely by age, with higher levels typical in younger women and gradual decline expected over time. There is no single target within the reference range, as context matters more than absolute number.

High AMH levels

High values usually reflect an increased number of small follicles in the ovaries, most commonly seen in polycystic ovary syndrome (PCOS). Elevated AMH is a hallmark of PCOS and correlates with irregular ovulation, hormonal imbalance, and metabolic effects. Very high AMH may also predict increased risk of ovarian hyperstimulation during fertility treatment.

Factors that influence AMH

AMH declines steadily with age and is unaffected by menstrual cycle phase, making it a stable marker of ovarian reserve. Hormonal contraceptives may slightly suppress AMH. Assay methods vary between labs, so trends over time are more informative than single values.
