Epigenetics & donor conception?
Many potential mums who are considering family creation through oocyte (egg) donation fell quite anxious that they are no more than a “third wheel” to their future child – that biology might somehow “trump” motherhood.
Often when I am talking to these women, I mention the emerging field of epigenetics, which, put simple, is the effect that nurture can have on nature. I have just discovered this wonderful website which explains epigenetics really clearly http://www.beginbeforebirth.org/the-science/epigenetics and even has a cool video to explain the action of the process http://www.beginbeforebirth.org/for-schools/films#epigenetics. I suspect that the years ahead will reveal just how much input a mother has on her developing baby, even if there is a genetic donor.
