In my opinion, the lady should have had the baby and handed it to the couple, in that way she would have been a surrogate mum for them as it looks like the couple that owned the embryo have problems concieveing
Instead of aborting the baby.
I heard the couples have been paid a large some of money, but it is not the money, it is the age,egg,sperm, embryo and the womb that is important for the baby to implant
I wish both of them all the luck they need
