•Determination of ovarian reserve can predict response to ovarian stimulation.•Response prediction can guide protocol and other reproductive therapy decisions.•Both AFC and AMH level provide good prediction of poor and excessive response.•AFC is quick and non-invasive, but subjective, with inter-operator variation.•AMH is objective, but currently lacks international standardization.
