Hell Comes to Frogtown (1987)

The ‘Hell’ of the title refers to Sam Hell, a man in a post-war world run by women. The war left the majority of the population sterile, but Sam’s not filled with blanks—he has the highest spermatozoa count on record. He’s tasked with seeking out fertile women and impregnating them, for his country, of course.
Roddy Piper does what Roddy Piper does best (other than wrestling, I guess), which is being the downtrodden hero in a world that has gone to shit.
