Can a sister be a surrogate for her brother?

I have had a tubal and an ablasion and I desperately would like to have a child with my new husband. Is it possible for his sister to be surrogate for us using my eggs and his sperm?

Yes, this is possible. Since his sister will not be donating her eggs with his sperm, it is not incestuous, just a really nice sister! It is the same, biologically, as a sister carrying a gestational pregnancy for her sister, or a mother carrying for her son or daughter.

This is one of the best situations you could have for surrogacy.

Best wishes!
