Nah, most of (all?) his kids seem to be ivf babies. It's either down to his need to have perfect embryos to choose from a bunch or he hates sex or he's ruined by porn or some combination of the three.
Honestly, I think that's part of which he has taken his one kid being trans so badly. He chose their gender for them before they were even implanted. How dare they try to change after he made the decision.
