Is not that, the problem is that he may have died for his body being weak while carrying a child, during childbirth, or after childbirth.
I think you missed my point a bit haha I brought this up because the story is a bit rush so it came across as if "he can't have children then suddenly now he can" that's all. But you're not wrong that if he had children there's a risk of dying. All ends well tho :✧)
I'll just look at it this way: ppl said he cant have children but how do they know or it could be an assumption from the beginning. So it can just be that his body wasn't ready for that or 'too weak' for pregnancy as how it turns out at the end..tho I definitely want more chapters of them being lovey dovey before having kid ╮(￣▽￣)╭ otherwise still a nice read :D
