“. A lot of people think “surrogacy” implies sexual intercourse with the surrogate. That is not going to result in his wife’s embryo being implanted in the surrogate”
Depends on the instrument used for implantation.
No it does not. An embryo is a fertilized ovum. A penis does not insert the embryo fertilized in vitro (outside the uterus) into the surrogate.
There is no sexual intercourse.
I have three children. One of them was fertilized in vitro and implanted into my wife. There was no sexual intercourse. There was no penis involved in the implantation of the embryo. The only difference is that my wife was the host, not a surrogate.
