Diminished Ovarian Reserve (DOR)

By RRM Academy Reviewed by Dr. Naomi Whittaker, MD, Board-Certified OBGYN, MIGS, NFPMC, FCI Updated May 7, 2026

A reduction in the quantity (and sometimes quality) of oocytes in the ovaries, leading to decreased fertility potential. Diagnosed by elevated FSH, low AMH, and low antral follicle count (AFC) on ultrasound. DOR is age-related but can occur prematurely. RRM takes an aggressive diagnostic approach, evaluating for autoimmune, mitochondrial, inflammatory, and lifestyle contributors. See Ovarian Reserve for interpretation of reserve markers in clinical context.³
