Study of pregnant male rats stirs controversy

Apparently, it will be possible in the foreseeable future that men may have babies! However, would it be possible for gestation to happen entirely outside of the human body?

Please remember the poor rats used in these experiments for science sake! Say a prayer for all the animals sacrificed daily for science!

"... Here, we constructed a rat model of male pregnancy by a four-step strategy: a heterosexual parabiotic pair was firstly produced by surgically joining a castrated male rat and a female rat. Uterus transplantation (UTx) was then performed on the male parabiont 8 weeks later. After recovery, blastocyst-stage embryos were transplanted to the grafted uterus of male parabiont and the native uterus of female parabiont. Caesarean section was performed at embryonic day (ED) 21.5. The success rate of modeling was only 3.68%, but 10 pups could still be delivered from male parabionts and developed. ..."

Study that Impregnated Male Rats Stirs Controversy | The Scientist Magazine® A combination of approaches, including uterus transplantation and the joining of two animals’ circulatory systems, allowed males to bear pups, according to a preprint. But some experts say the experiments were not justified.
