Male pregnancy is the incubation of one or more embryos or fetuses

Male pregnancy is the incubation of one or more embryos or fetuses by male members of any species. In nearly all heterogamous animal species, offspring are ordinarily carried by the female until birth, but in fish of the Syngnathidae family (pipefish and seahorses), males perform this function.[1] There are different ideas concerning whether a human male could become pregnant, and, by some definitions of gender identity, human men have become pregnant.

 Male humans incubating fetuses are also a recurring theme in speculative fiction.Human males do not have the anatomy needed for natural embryonic and fetal development.[1] The theoretical issue of male ectopic pregnancy (pregnancy outside the uterine cavity) by implantation in biological males has been addressed by experts in the field of fertility medicine, who stress that the concept of ectopic implantation, while theoretically plausible, has never been attempted and would be difficult to justify – even for women lacking a uterus – owing to the extreme health risks to both the parent and child.

Robert Winston, a pioneer of in-vitro fertilization, told London's Sunday Times that "male pregnancy would certainly be possible" by having an embryo implanted in a man's abdomen – with the placenta attached to an internal organ such as the bowel – and later delivered by Caesarean section.[10][11][12] Ectopic implantation of the embryo along the abdominal wall, and resulting placenta growth would, however, be very dangerous and potentially fatal for the host, and is therefore unlikely to be studied in humans.[10][13] Gillian Lockwood, medical director of Midland Fertility Services, a British fertility clinic, noted that the abdomen is not designed to separate from the placenta during delivery, hence the danger of an ectopic pregnancy. "The question is not 'Can a man do it?'" stated bioethicist Glenn McGee. "It’s ’If a man does have a successful [ectopic] pregnancy,
