Poor ovarian response

Very few follicles or eggs despite adequate stimulation.

IVF & IUI

Poor response is usually defined as three or fewer eggs after conventional stimulation, often with low AMH or a low antral follicle count. Changing protocol may help modestly, but the strongest determinants remain age and reserve. Options discussed include repeated collections to bank embryos, and donor eggs.

Also known as: low responder, poor responder
