Anti - Mullerian Hormone (AMH), in Visit Clinic

An AMH level above about 1.0 ng/mL is generally considered adequate for natural conception; 1.5–3.5 ng/mL is often regarded as normal/good ovarian reserve. Levels 0.5–1.0 ng/mL are low–normal, and below ~0.5 ng/mL suggests diminished ovarian reserve. Interpretations vary by age and lab; fertility potential depends on multiple factors beyond AMH, so discuss results with a clinician.

Anti‑Müllerian hormone (AMH) is produced by ovarian granulosa cells of preantral and small antral follicles. It helps regulate follicle development by limiting recruitment of primordial follicles and reducing follicle sensitivity to FSH. Clinically, AMH levels reflect ovarian reserve (quantity of developing follicles), are used to estimate response to fertility treatments, and are low with diminished reserve or after menopause and often high in PCOS.

Low AMH indicates reduced ovarian reserve—fewer eggs—but it does not automatically mean infertility. Women with low AMH may have lower chances per cycle and a poorer response to stimulation, especially with advancing age, yet natural conception is still possible. Fertility depends on egg quality, age, and other factors; discuss evaluation and treatment options with a fertility specialist.

AMH normally falls as you age. Typical ranges (approximate): 20s: ~2–6 ng/mL; 30–34: ~1.5–3 ng/mL; 35–39: ~1–2 ng/mL; 40+: often <1 ng/mL. Levels <0.5 ng/mL suggest low ovarian reserve; >1.0 ng/mL generally indicates adequate reserve. Laboratory assays and units vary, so review your result with a clinician for personalized interpretation.

High AMH usually indicates a good ovarian reserve and does not by itself prevent conception. However, very high AMH is often linked with polycystic ovary syndrome (PCOS), which can cause irregular cycles and anovulation that may reduce fertility. With PCOS or other concerns, treatments like lifestyle changes, ovulation induction, and assisted reproduction can help—consult a fertility specialist for personalized evaluation and management.

To assess egg quality, clinicians use ovarian reserve tests: anti‑Müllerian hormone (AMH) blood levels, early‑cycle follicle‑stimulating hormone (FSH) and antral follicle count (AFC) by transvaginal ultrasound. Age and medical history (e.g., chemotherapy, smoking) also inform risk. Definitive assessment often requires IVF with embryo genetic testing (PGT‑A). Discuss results and options with a fertility specialist.
