I found one article regarding a transgendered WOMAN (now living as a man) who kept the "original equiptment" and is pregnant.

However there is also a man (genetically, physiologically and socially) in NYC who is undergoing a pregnancy using an experimental procedure IVF techniques were used to induce an ectopic pregnancy by implanting an embryo and placenta into the abdominal cavity, just under or into the peritoneum (the surrounding lining).
Delivery will be by cesearean section.
