This one is not porno. I was just perusing http://yoni.com/loverf/christiangspot.shtml and on page 3 it says: "In-vitro we all start out as female. If we get certain chemicals our development changes to male and our female organs dry up and we develop male."
Sort of shoots the "Adam's rib" theory all to hell. Never seemed very believable anyway. Seems the egg may have come before the chicken.
Sorry, all you Macho Tyrannicuses out there.
