Don't tell Carlson, but the Chinese are coming after his precious bodily fluids

I noticed this a few days ago:

and then read this today (my bold):

In a new paper published by Nature Communications, The Lundquist Institute (TLI) Investigator Wei Yan, MD, Ph.D., and his research colleagues spell out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models. Despite tremendous efforts over the past decades, the progress in developing non-hormonal male contraceptives has been very limited.  

The compound is triptonide, which can be either purified from a Chinese herb called Tripterygium Wilfordii Hook F, or produced through chemical synthesis. Single daily oral doses of triptonide induce altered sperm having minimal or no forward motility with close to 100% penetrance and consequently male infertility in 3-4 and 5-6 weeks. Once the treatment is stopped, the males become fertile again in ~4-6 weeks, and can produce healthy offspring. No discernable toxic effects were detected in either short- or long-term triptonide treatment.

So, don't put it past the conspiracy addled brains of the Right to come up with a story that the Chinese have putting triptonide in the water supply of the West in a long term plan to out populate it.

More seriously - it would be pretty incredible if a natural compound found in a herb really did prove to be a super effective and safe male contraceptive.
