Diminished Ovarian Reserve
Also written as: DOR — Diminished Ovarian Reserve
A condition characterized by reduced quantity and quality of eggs in the ovaries.
Full Definition
Diminished ovarian reserve refers to a decline in the number and quality of oocytes available in the ovaries, which naturally occurs with aging but can also affect younger women due to genetic, medical, or surgical factors. DOR is diagnosed through various markers including elevated FSH levels, low AMH levels, and reduced antral follicle count on ultrasound. Women with DOR typically have poorer responses to ovarian stimulation, lower pregnancy rates, and higher miscarriage rates. Management may involve modified stimulation protocols, donor egg consideration, or fertility preservation counseling.
Usage
Usage note: Provide specific biomarker values when documenting DOR diagnosis.
