I just ran across this in a google search. Hell Comes to Frogtown starring former professional wrestler Rowdy Roddy Piper as Sam Hell. I saw it on TV one time late one night Sam Hell is a prisoner of the female faction who took over the USA after nuclear war. Mutants thrive in the wasteland while humans face possible extinction due to infertility. Hell is forced to rescue a group of fertile women from a harem ran by an evil mutant gang.
