The Last Straw | 1986
Set in a world where the human population is dwindling, a middle-aged man named Alex learns that his sperm is particularly strong and is more than willing to do his part to help boost the population. There's a catch, though. Alex is no Adonis. To drum up interest, he hires a manager to advertise his gift to the world. Pretty soon, ambassadors from countries all across the globe request that he help build up their populations. But then, Alex gets kidnapped.
