Following the publication of "The Amazing Spider-Man" #121, Stan Lee (who had since become Marvel's publisher) was frequently criticized by fans during his public appearances for killing off Gwen Stacy. Lee, who had also found the character's death objectionable, insisted that Conway write a story bringing her back. Conway strongly objected since he felt any sort of resurrection would break the plausibility of the stories, but ultimately gave in under the condition that after reviving Gwen, he could write her out of the book as soon as he wanted. He decided that cloning would be the best means to bring the character back.
