Male pregnancy
Since 2000, several hoax web sites have appeared on the Internet purporting to describe the world's first pregnant man. While some rely on legitimate scientific claims, no such experiment has ever been reported. Fertility clinician Cecil Jacobson claimed to have transplanted a fertilized egg from a female baboon to the omentum in the abdominal cavity of a male baboon in the mid-1960s, which then carried the fetus for four months; however, Jacobson did not publish his claims in a scientific journal, and was subsequently convicted on several unrelated counts of fraud for ethical misconduct.
