This is incest.
I think not a month goes by without some news item about a female who volunteers her womb to carry an in-vitro embryo for a family member. Most times it’s not even worth a news story because it’s a fairly routine medical procedure by now. It’s even been a more then a decade since “Friends” did an arc of shows where Phoebe carried her brother and his girlfriend’s children.
Other then now we see modern medicine has reached Mexico, so what?
>>> This is incest.
That is ignorant. There was no family to family sexual contact whatsoever. The ovum was from a third party.
