About Anti-Mullerian Hormone
AMH (Anti-Mullerian Hormone) is produced directly by ovarian follicles and is the most reliable blood marker of a woman's remaining egg supply (ovarian reserve). Unlike FSH, AMH doesn't fluctuate significantly with the menstrual cycle, making it useful at any point in the month. Very low AMH indicates diminished ovarian reserve and reduced fertility window; very high AMH is characteristic of PCOS. AMH is routinely measured before IVF to predict ovarian response to stimulation.
