Anti-Müllerian Hormone (AMH) levels are often measured as part of a fertility assessment. AMH is produced by granulosa cells in ovarian follicles and reflects the size of the ovarian reserve. AMH levels indicate the quantity of eggs remaining in a woman's ovaries. High AMH levels generally suggest a good ovarian reserve, while low levels may indicate diminished ovarian reserve. AMH levels can assist in predicting a woman's response to ovarian stimulation during IVF. Women with higher AMH levels may produce more eggs during stimulation. AMH levels are relatively stable throughout the menstrual cycle and can be measured at any time. It is important to interpret AMH levels in conjunction with other fertility markers.
