The Telegraph reported that a lesbian couple each gave birth to twins. What occurred was the use of a single sperm donor, while one of the Couple donated her eggs. Apparently, at least four of the eggs were fertilized, two of which were carried by each partner.

Medically and legally this is called a shared cycle, where a donor's eggs (as well as the IVF costs) are shared between two or more women. The eggs can be shared between an intended mother and a gestational carrier, between two intended mothers who are strangers to each other or as occurred here, between partners.

From a legal perspective these were very smart women. Why? Generally the birth mother retains all parental rights, while the donor loses all parental rights. That is because donations are deemed to be absolute. So, a lesbian couple who assign donor - birth mother roles to each other, place the donor at risk of no contact with the child or children should the couple separate in the future. This is another of those inequalities faced by same sex couples while the state legislatures decide their legal status.  This issue has been before many judges and the rulings are consistently against the donor.

So, by sharing the donation, this couple also share birth mother status and escape the probability of no contact. I like it!
