"No study has ever substantiated this statement. It is totally false," Dr. Chalas said. While someone may struggle to get pregnant after having the vaccine and just assume the two are linked, "it's common for couples to be infertile, so essentially until you try to get pregnant you don't know if you're going to be successful or not," she explained. There's just no evidence to connect the two, and again, not vaccinating and then contracting HPV poses its own risks to a person's fertility.
