Spermula

The Spermulites, shapeless inhabitants of a dying planet, decide that the only way to save their planet is by conquering that disgustingly carnal planet Earth. To do so they transform themselves into the bodies of attractive women - except for Werner (Udo Kier), who is accidentally transformed into a hermaphrodite - and attempt to suck the life out of all the men on Earth (kind of like horny vampires)!
