I wouldn't be surprised if he was hoping for triplets, to be honest, and that's why three were transferred.
I read his claim that it was done without his knowledge but privately paid for fertility doctors, whether they are in Kenya, Ireland or Ukraine, will not spend the time and resources preparing 3 embryos (when one will do) if this hasn't been agreed and paid for.
To imply it was done without knowledge and consent also suggests that the doctors are not operating within limits and can 'go rogue'. I have no experience of Kenya's fertility clinics but I very much doubt that it wasn't a very deliberate act, like the rest of the surrogacy arrangement. I also like to think that the surrogate mother knew before all three were transferred.
Now that he has these three, prematurely born, newborn baby girls I hope he doesn't need another crowdfunder for nappies and formula. I'm surprised at the speed this was done and can only guess that the legal granting of parental rights and permission to leave the country was done quickly to get rid of him and transfer the babies to a country with a national health service.
One day these children will learn what their fathers did. At least one of them will need to formally adopt them to obtain any legal parental rights and this will all be documented and their mother will also be named on the original birth certificate.
