Some people are not biologically able to have children. But for them science has made excellent advances, such as gestational surrogacy.
In a gestational surrogacy, an embryo is transferred to the woman who agrees to gestate the baby, the gestational carrier. The baby has no genetic material from the carrier. Here is where it gets confusing: The gametes can come from either of the intended parents (or both), or from an egg donor or a sperm donor, or both.
It is important to create parenting presumptions in law so that the intended parents are the legal parents. Texas is one of the states that has taken steps to legally clarify gestational surrogacy.
