A research team thinks it may be able to stop sperm production for up to six months using ultrasound, the same instrument used to look at fetuses in the womb, an often-occurring side effect of sperm:
University of North Carolina researchers, working with a $100,000 grant from the Bill & Melinda Gates Foundation, think that delivering a single dose of ultrasound to the male reproductive organs can stop sperm production for six months, after which time production fires up again.
Perhaps the best part: it’s non-hormonal, low-cost, and once treated the man has to do/remember absolutely nothing to remain infertile for up to half a year. Such an inexpensive and widely available method of stopping sperm production long-term — but not permanently — has plenty of appeal in the first world, but could be a serious boon for developing nations dealing with overpopulation and poverty.
The work is still preliminary, but the team is pushing forward with more clinical trials aiming to tweak the technique for optimum safety, as well as the greatest effect. In the meantime gents, we don’t recommend any attempts at self-medicating with unattended ultrasound machines. As with any experimentation that requires you to take off your pants, we recommend you let the professionals get a bit further along in the lab before trying this at home.
