The Syngnathidae family of fish has the unique characteristic where females lay their eggs in a brood pouch on the male's chest, and the male then fertilizes and incubates the eggs. Included in Syngnathidae are seahorses, the pipefish, and the weedy and leafy sea dragons. Syngnathidae is the only family in the animal kingdom to which the term "male pregnancy" has been applied. http://en.wikipedia.org/wiki/Male_pregnancy

Honestly I do not know but I would like to know more about this phenomena because in my opinion it is brilliant! What do the human males think of this? Thanks so much!

The female seahorse deposits her eggs in a special pouch the male has, and then leaves. They are fertilized there, and the male carries them till they hatch. Not true "pregnancy", but close enough. I have seen films of male seahorses "releasing" the newly hatched babies. Hundreds of them. Truly amazing.

Oh, are you taking it in to consideration how cute those lil seahorses are? Oh they are mesmerizing to watch..yes i got off the point oh well

Male seahorses do not get pregnant! They do not produce the eggs themselves. They receive from the female a brood pouch (egg sac). The male then carries the egg pouch in a pocket somewhat like a kangeroo's. He may or may not fertilize the eggs right away.It is all dependant upon environmental stresses and threat levels from predators.The male may wait weeks before fertilizing the eggs so as to ensure that the offspring hatch at a time when their chances for survival are greatest. When the father ejects them from his pocket, the young are fully formed small versions of the adults and must fend for themselves.the parents do not have any part in their offsprings lives after birth.

The male seahorse carries the fertilised eggs. I have never heard of another species that does this.

I wish I could remember the species for you, but there is a fish out there (probably several species) that can change their sex from male to female or vise versa depending on the schools' need for male or females to reproduce. Not quite on the 'males having babies' subject, but amazing nonetheless.

The answer has already been given by Twistiburger for the animal kingdom. Here, as a complement, some information about humans: "Speculation on inducing pregnancy in men British physician Robert Winston speculates that it may be possible to surgically induce abdominal ectopic pregnancy in men. In his book The IVF Revolution, Winston speculates that an embryo could be implanted in a man's abdomen—with the placenta attached to an internal organ such as the bowel—and that the baby would later be delivered by Caesarean section. However, other experts expressed great concerns about the safety of such a procedure. Pregnancy among transsexual and intersex people Some intersex people with XY chromosomes develop entirely female bodies and, if the individual develops a uterus, in vitro fertilization is possible. This may also occur in animals. Some female-to-male transsexuals who interrupt hormone treatments can become pregnant, while still identifying and living as male—this is possible for individuals who still have functioning ovaries. One example is Matt Rice, a transman who is the former partner of writer Patrick Califia. Rice bore a child by artificial insemination. Although the individual is genetically and physiologically female, from an identity standpoint this may be considered a "male pregnancy"."
