The placenta would shrink after the birth, thus possibly rupturing the blood vessels attached to it. There would also be a high risk of infection caused by the dead placental tissue. Without a womb to protect it, the fetus would be in an unusual position and under unusual pressures, which could cause malformation of the limbs or organs.

There would also be a high risk of premature birth, either as a result of abdominal pain or a rip in the amnion, the membrane surrounding the fetus. McGee estimates that male pregnancy is 20 years away, but others believe Lee Mingwei's prank is as close as we'll ever get.

Although biologists' definitions of pregnancy differ somewhat, all members of the family are considered by ichthyologists to display male pregnancy, even those without an external brood pouch. Fertilization may take place in the pouch or in the water before implantation, but in either case, syngnathids' male pregnancy ensures them complete confidence of paternity.

This period of incubation can take much longer than the production of another clutch of eggs by the female, especially in temperate regions where pregnancies last longer, [4] leading to a reproductive environment in which sexual selection can be stronger on females than on males due to increased male parental investment.
