I'm smiling as I am also a catholic and a scientist. Its interesting isn't it
As for the person wanting to become a priest well good for him but that is him and his beliefs.
This is all about you.
My belief is god put doctors here and IVF here to help us. He put DE here too. I"ve been a catholic for 48 years now trust me I'm an expert
We are fortunate to have DEIVF as an option. This is about you and nobody else. Everyone is entitled to their opinion but...
Also wanted to add that because he is only just starting at the seminary he will be naturally dogmatic. I know our local priest here (who baptised our son BTW) thinks IVF is great.
Good luck with your cycle go fo it
, best, THK
