Poor ovarian response

When the ovaries produce fewer follicles than expected during stimulation.

IVF & treatment

Poor response is often linked to lower ovarian reserve or age. The clinic may adjust the protocol in a future cycle or discuss other options. It does not mean pregnancy is impossible, but it can lower the chance per cycle.

Also known as: low responder, poor responder
