Follicle Stimulating Hormone (FSH) and Anti-Mullerian Hormone (AMH) are both laboratory tests checked during a fertility evaluation to determine if a woman has decreased ovarian function. Decreased ovarian function, as suggested by a high FSH or low AMH, means a woman’s egg (oocyte) supply is partially or completely depleted and she may have difficulty getting pregnant or have symptoms of low estrogen. A pelvic ultrasound can also be used to determine if a woman has a decreased egg supply which is suggested by a low ovarian antral follicle (maturing egg) count. As a woman ages, her egg (oocyte) supply gradually decreases since she is born with a limited supply of eggs. An elevated FSH, decreased AMH or decreased antral follicle count (AFC) is expected in women above the age of 40. Evaluating if a woman’s egg (oocyte) supply is further depleted than expected for her age will help with the selection of the best fertility treatment for her situation. The selection of an appropriate treatment will shorten the time to pregnancy while reducing or eliminating unnecessary frustration for the patient.
