My husband wants me conceive in a non-sexual way. Is this normal?

This is not a troll question. I been married for 2 years to a really bright man who's a PhD holder. We both want a baby. He doesn't want to have sex with me to conceive. Instead, he wants to ejaculate and inject it in me with a syringe. He says he finds disturbing that people come to this world through sex.
Update: He's just one of those people who think deeply about every thing and to be honest I agree with him.
Update 2: My husband is Agnostic but was raised in a very religious Orthodox Christian family that frowned up sex.
