Premise debunked in two words. (SPOILER)
Whiskey Dick. How did he achieve an erection, let alone provide an adequate sample for the insemination, whilst so intoxicated. Yes it was a mix of booze and a pharmaceutical, but the point remains. Okay more than two words and it is only a movie and what happens, happens because it is on the page. Just sayin'.
Well ain't this place a geographical oddity, two weeks from everywhere!
