Digital penetration cannot cause a pregnancy because it does not involve the insertion of semen into the vagina. A woman must have vaginal sex or some type of insemination to get pregnant according to WebMD. Oral sex, masturbation, anal sex and object penetration are all incapable of causing pregnancy.
