Well, I've been beaten to the actual issue, but I suppose this (http://www.steelcaves.com/ezine/vol2/is3/superman2.htm) supplies you with a plot summary:
* BIG SISTER SYBIL - A hideously deformed alien who, from the anonymous perch of her spaceship/monolith, controls the Southern town of BELTON in October 1975 (WF#233 "World Without Men"). Hating all things of beauty, Sybil infects the all-female population of the town with a slow-acting serum which will eventually turn the beautiful women into terribly deformed monsters. The SUPER-SONS manage to defeat Sybil and send her back to her homeworld (there she is punished by being caged in a mirrored prison, where she must view her hideousness "for all eternity"), and administer the antidote to her serum - "a male's touch."
