Interesting that "penis" wasn't on the list of terms they were going to use, but "vagina" and "uterus" is. You're going to completely leave out that a penis is crucial for reproduction? What, do you want kids thinking that scissoring will produce a baby? I get that she's trying to be "inclusive" or "gender neutral" or whatfuckingever but that doesn't work when you are talking about mammal reproduction. She's giving information that is more confusing than just saying the standard.
"Testicles produce sperm. Penis lets out semen, which is how sperm get out of the body. Ovaries produce eggs which travel into the uterus. The passageway to the uterus is called the vagina. When sperm reaches egg, that is called fertilization. The sperm/egg combine in the uterus and take 8 to 9 months to turn into a baby."
It's not that complex or "gendered".
