Abstract
Objective: To determine whether anti-Mullerian hormone (AMH) production resumes during normal late menopausal aging. Anti-Mullerian hormone has been proposed as a specific serum marker for adult granulosa cell tumors.
Materials and Methods: Serum AMH from 21 elderly postmenopausal women (mean age, 77 years) and 9 young women (mean age, 22 years) were measured by ultrasensitive immunoassay.
Results: Both median (0 pmol/L) and mean (0.48 pmol/L) serum AMH values for the elderly women were below the level of detection for the immunoassay kit. Three of the 21 participants had minimally detectable level of AMH (1.13-2.76 pmol/L). The cohort of young women had expected normal values of AMH as measurable by the same immunoassay kit.
Conclusions: Serum AMH values were negligible for postmenopausal women older than 65 years. This extends the normative data for AMH to 108 years old, providing a reference range for the detection of granulosa cell tumors in postmenopausal women.
