A blast of ultrasound waves can do what?

Scientists and their wonderful brains. It would seem that some folks at University of North Carolina (Chapel Hill to be exact, there are several UNC campuses in NC) have learned that blasts of ultrasound to the testicles can temporarily stop sperm production. Not only that but the Bill and Melinda Gates Foundation has given a $100,000 grant to continue clinical trials.

I tell you what along with other recent developments it seems like we are not too far off from a time where a guy can go to the doctor and get a prescription or go in for an outpatient treatment for birth control.

To be exact though this particular method is only temporary with sperm production only being stopped for about 6 months and even when the procedure is done that only stops production of new sperm cells for the timespan. That seems to mean that any sperm that are already present in the testicles at the time the they are hit with the ultrasound blast are not killed and are thus still able to fertilize an egg, thus causing pregnancy. Sounds like to get the full effect a guy would need still ejaculate the last of his remaining sperm in order to actually be infertile for the timespan.

So it seems that researchers (and funders wow The Gates backing this is a pretty big deal, well at least to me) are finally starting to see that there are men out there who want methods of birth control beyond condoms.

Who knows maybe by the time I get around to that whole sexually active status thing there will be multiple birth control options for me to choose from.
