RT Journal Article SR Electronic T1 Having a child together in lesbian families: combining gestation and genetics JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 253 OP 255 DO 10.1136/medethics-2015-103007 VO 42 IS 4 A1 Guido Pennings YR 2016 UL http://jme.bmj.com/content/42/4/253.abstract AB The increasing acceptance of lesbian couples in medically assisted reproduction has led to new, unusual requests. This paper discusses the request for egg transfer from one partner to the other. In the first part, different analogies (egg donation, embryo donation, surrogacy and mitochondrial replacement) are made in order to find out whether one of these can help us determine whether this procedure is acceptable. It is shown that there are major difficulties with all analogies. In the second part, two balances are developed between the medical risks and costs of in vitro fertilisation (IVF) and intrauterine insemination on the one hand and the medical risks of IVF and the psychosocial benefits on the other hand. The final conclusion is that the disadvantages of the procedure can be compensated by the psychosocial advantages and thus can be accepted.
