Poor ovarian response

Few follicles or eggs despite adequate stimulation.

Treatment

Poor ovarian response usually means three or fewer eggs collected after conventional stimulation, often with low AMH or antral follicle count. It reflects the number of eggs available rather than a failure of treatment. Options include adjusted protocols, higher doses, cycle banking, and — depending on age and expectations — considering donor eggs.

Also known as: low responder, POR, poor responder
