In a new study from the Naval Medical University in Shanghai, researchers explained in horrific detail how they castrated a male rat, conjoined him with a female rat, then transplanted a uterus into him which they later delivered a baby rat from via caesarean section.

"Here we investigated the question of whether male pregnancy with livebirths can be achieved in a rat model if the speculative problems were solved by existing methods," the study's introduction states.

"The success rate of modeling was only 3.68%, but 10 pups could still be delivered from male [conjoined rat] and developed," the researchers excitedly reported in a study published at

"For the first time, a mammalian animal model of male pregnancy was constructed by us," the scientists wrote.
