You will find probably some sort of biologic programming linked with one to. While doing so, the guy contributes, the newest uterus doesn’t decades-it is simply the newest ovaries, that is the reason pregnancy can happen inside earlier feminine playing with good donor egg.
In addition, specific existence items, connection with environmental poisonous drugs together with pesticides and you will agents within the plastic materials (such as for example bisphenol An excellent), and you can certain diseases may affect egg high quality.
