Medical science keeps trying to find a way to secure for men the ability to get pregnant and deliver babies. Technically, men have given birth before but those were men who had the necessary uterus because they’re transgenders. Take for example the case of Thomas Beatie, a transgender, who chose to get pregnant because his wife was infertile.
Hollywood has been playing with this possibility in several films already like the Arnold Schwarzenegger and Danny DeVito movie “Junior”.
