>>11780938I am illiterate, so I can only guess at what you've written here. I'll take a shot in the dark and guess that you confused the term "sexual dimorphism" with "secondary sexual characteristics". I will also speculate that you failed to notice OP's post mentioned nothing about successful mating, but instead focused specifically on the process of pregnancy and child birth.
OP even highlighted this point by generously including a picture of the human birth canal, which is the only reason I understood OP's meaning since I am in fact illiterate.
