In a development sure to please ex-wives, scientists in Japan may have made men obsolete.
According to Nature, a magazine for people with giant brains, the scientists were able to grow sperm from long-frozen neonatal mouse testes, aka baby rodent testicles.
Sperm, complete with iconic flapping tails (aka flagella), was “grown” by soaking the tissue in a fluid used to harvest embryonic stem cells, according to the article.
The researchers injected the man-made sperm into egg cells. A few weeks later, surrogate mouse moms delivered fatherless children who will never learn how to properly appreciate baseball.
It’s quite the breakthrough. Allegedly, highly intelligent men have been trying to grow lab sperm for almost 100 years with no success.
The new technique may eventually help infertile males and endangered species, which may include men if female scientists ever get wind of this.
