I have had flashbacks to a film I once saw on tv as a young lad. It stuck with me, but I’ve never been able to find it again.

It would have been on UK TV late night poss channel 3 or 4 around the late 90s. It felt older than that so maybe 70s/80s. It was American, set in what would have been modern (dystopian) times? I recall a factory and someone managing to break in (very Soylent green style) however, inside, people (possibly just men) are on a conveyor belt, moving along. As they do, a small guillotine chops their male organ off and hey presto, they come out the other end as women…

I swear this existed and it wasn’t a dream! I’ve scoured the web, but there were so many low budget films back then, I’m drawing a blank - I don’t want to force myself to watch 3 decades of films I probably can’t now even get hold of!
