There is movie called Swallowed, its not about pregnant man but has scene like make give birth
Its about men swallow a parasite kind of thing
Interesting scene btw

I broke down and rented this, there's not much as far as belly content goes, but there's some mediocre to good "birthing" sequences and lots of male nudity.

It borders more toward if The Immaculate Conception of Little Dizzle was a horror/thriller movie.
