Method of improving ovarian reserve in a human female with diminished ovarian reserve as measured by the females anti-Müllerian hormone level. The method may include evaluating a first anti-Müllerian hormone level of the female, administering an androgen, such as dehydroepiandrosterone or testosterone, to the female for at least about one month, and then evaluating a second anti-Müllerian hormone level of the female. Change in the anti-Müllerian hormone level is indicative of change in the ovarian reserve, e.g., when the second anti-Müllerian hormone level is greater than the first anti-Müllerian hormone level, the ovarian reserve has improved. The androgen administration may continue until the second anti-Müllerian hormone level is greater than the first anti-Müllerian hormone level by a desired percentage or amount.
