Male pregnancy and abortion: The sex life of pipefish - Yahoo! News
excerpt from above:
Quote:
The male pipefish can carry between five and 40 offspring in its transparent pouch, and nurtures them to term after a pregnancy lasting between 12 and 14 days.

But a new study shows that the pipefish is more than a piscatorial gender-bender.

It also chooses which of the brood survives, on the basis of the mother's attractiveness.

excerpt from above:
Quote:
Kim Paczolt and Adam Jones, researchers in the Department of Biology, found that the male pipefish can be a nurturing father as it tends its young before giving birth, but later it may not choose to make the effort. The key factor for this attitude: How the male feels about the mother.
The study was funded by the National Science Foundation and the findings are published in the current issue of Nature magazine.

The Texas A&M researchers studied consecutive broods in male Gulf pipefish to understand why some offspring survive while others do not. Their results reveal that...

Male Pipefish (and seahorses) cannot get pregnant. The male didn't produce the eggs he carries, the female did, and she then placed them in the male's pouch, so he's just tending to the eggs while they develop. I find this to be annoying and misleading when they use terminology like "pregnant male" in talking about seahorses and pipefish, but I guess that's typical of the media nowadays, go for the hook even if they have to bend the truth.

Here's a definition of pregnancy that makes sense to me:

pregnancy - The period following conception during which a developing embryo and later fetus is carried within the uterus.

From what I can see, only a female can truly be pregnant. My $.02 worth anyway.

Aw shucks jpdenk. Your definition is somewhat dated. Arnold Schwarzenegger's character in the movie Junior is proof.
