Weird alert! Besides enhancing the pectorals of the male species, male nipples can actually play a purpose other than decoration. Since men posses both mammary glands and pituitary glands––the essentials for lactation—they also have the ability to breastfeed. When the factors align properly, some doctors believe that men can partake in nourishing their children in the same way as women. Though this doesn’t happen in everyday circumstances, in some rare instances, men have been the breastfeeders.

Thomas Beatie, the world’s first pregnant man, shot to insta-fame when he appeared on “Oprah” last year. He gave birth to a baby girl in July 2008. And he just popped out his second kid—this time, a boy. So how exactly does a dude get knocked up? Turns out Thomas was born a woman, and while he had a sex change, he didn’t undergo phalloplasty. In other words, he doesn’t have a penis, and all of his female reproductive organs are still in tact. Since his wife, Nancy, had a hysterectomy, they decided that Thomas should carry their children rather than adopting or getting a surrogate. But even though Thomas was the one doing the pushing, he’ll assume the father role while Nancy takes over as mama. She’ll even be breastfeeding the new baby.
