1976 film by Giulio Berruti

A prisoner is forced to serve as a doctor's assistant, giving her a front row seat for the horrible goings-on. There's the experiment to revive Nazi soldiers who have frozen to death by having nude women rub their bodies all over the corpse (that one works), and the experiment tries to "cure" homosexual men by having nude women dance for them. This is only some of the horrors that are going on there.
