Yeah, that statement was rather absurd.
Pregnancy results from intercourse, whether consensual or not.
I don’t know, because it can’t be tested! (Certainly pregnancy results for me, but for a lot of others, it doesn’t.)
Much of what is claimed to be “scientific fact” about conception and fertility is simply theorizing, because it’s impossible to assemble an experimental population of women with uncompromised fertility and match them with a population of equally healthy, fertile, and virile men in order to test a hypothesis.
