I was reading recently about the scientists who have found they can create a mouse embryo from the cells of two male mice. As it happens, my DP works in cell culture, and when we were TTC our DD, she mentioned that she knows the theory of how you would create an embryo from two female parents. It's very hard to know how the science will develop, and there are serious moral questions to be answered, but it is possible that large parts of this debate will become obsolete, if same-sex couples can have a biological child together. IMO, IVF ought to be available to lesbian couples and to straight couples, who haven't been able to conceive otherwise, or who have a poor chance of conceiving. My thinking is that sperm donation carries no known health risks. I am not sure how I feel about surrogacy; I think is much more worrying. I think lesbians ought to have done IUI if medically recommended, but that ought to be funded. It is relatively cheap. I don't think recommending 'turkey baster' options would be ethical.
I have a huge issue with these decisions being made on the basis of sexuality rather than medical history. It results in failures of basic common sense and kindness. When I met my DP (who is a woman), I had a history of miscarriages, from a previous heterosexual relationship. If DP had been a man, my GP would have referred me for NHS treatment. She was able to refer me to the recurrent miscarriage clinic, but that was it. I have a friend in a same-sex relationship: she and her wife had six miscarriages within two years, but because they (sensibly, and following medical advice) alternated attempts to get pregnant through IUI, neither of them 'counts' as having had the requisite six attempts at IUI that her NHS trust required for IVF treatment.
As the mother to my female partner's biological daughter, I can't help feeling slightly disturbed by all the unrest over this issue. In 2023, we know that children do not develop according to some unchanging computer-programme system written in their DNA before birth. My daughter has two mothers who love her. I'm ok with that.
