Oxidative stress and ageing of the post-ovulatory oocyte

postovulatory ageing occurs both in vivo and in vitro and has been associated with reduced fertilization rates, poor embryo quality, postimplantation errors .

oxidative stress and ageing of the post

postovulatory aging is associated with excessive accumulation of ros leading to oxidative stress, which predisposes aged oocytes to the apoptotic process [9, 21] .
