[Children of Men] Are women still menstruating?
gpt
I remember in the book that it was a problem with the men's sperm count.  In the book, the main character is talking with a nurse who worked in the fertility ward of a hospital and she said she remembered thinking "what is wrong with the men of this country".  And also near the end of the book when a male child is born, the leader of the country plans to have him start impregnating the female members of the youngest generation when the boy reaches 13 and he isn't concerned at all about female infertility.  Meaning, that yes, the women menstruate as the lack of children is the fault of men.
