Hello there guys,

here’s an interesting sperm-related story for all your boffins out there. It seems those wonderfully ingenious Japanese, always obsessed with the science of the tiny, and indeed with cum, have cone up with the first lab-grown spunk. I wonder what they’ll do with it once they’ve got a petri dish of sticky, lumpy, white jizz? Probably throw it in the face of the cutest researcher I reckon. Then add some more.

Maybe the hi-tech future is drenched in cock essence and commercial cum farms dot the horizon where buckets of jizz is manufactured for semen addicts such as Yuria or Ai?

Sperm have been
successfully grown in the laboratory for the first time and it is hoped
the technology could eventually help infertile men have children. In the experiment on mice, the sperm were used to produce healthy, fertile offspring. The researchers, writing in Nature, say their method will serve as a platform for future clinical applications.

A UK expert urged caution as many more studies were still required. The research team have described sperm production as one of the longest and most complex processes in the body.

It takes more than a month from start to finish in most
mammals and scientists have struggled to produce healthy sperm in the
laboratory. Rather than working with individual cells, the team in Japan
used fragments of testes. It is like starting with a whole segment of an
orange rather than just the juice. The fragments were then bathed in nutrients and sperm production was maintained for more than two months.

Cancer

Some treatments for cancer, such as chemotherapy and
radiotherapy, can result in fewer sperm being produced and reduce the
ability of sperm to fertilise an egg. Patients can freeze sperm before undergoing treatment,
however, this has limitations. It is only possible to store so much,
sometimes it fails and young boys have no sperm to freeze.

It is hoped the research at Yokohama City University will be able to help. The study shows that mouse testes can be frozen until needed and still produce sperm.

A review article in Nature, by Marco Seandel and Shahin Rafii
who are both from the Weill Cornell Medical College in New York, said
the “approach represents a crucial experimental advance along the thorny
path to the clinical use of sperm” developed in the laboratory.

Dr Allan Pacey, a senior lecturer in andrology at the
University of Sheffield, believes that being able to grow human sperm in
this way will lead to better understanding of infertility and would be a
better subject for testing drugs. On clinical developments, he added: “It is important to be
cautious because sometimes species-specific differences in biology means
that what works for one species does not work in another.

“Also, it is clearly important to make sure that any sperm
produced are safe and give rise to healthy offspring when used, and that
they in turn have healthy offspring. We need to be cautious with this
kind of work.”
