A single dose could last six months

Contraception for Men A simple dose of ultrasound twice a year could be the elusive male contraceptive researchers have been searching for, minus the hormonal drugs. Bobjgalindo

The birth control pill turns 50 this month -- the birth control pill for women, that is. While researchers have searched for a hormonal contraceptive pill for men for at least that long, so far they've been unsuccessful. Men produce a thousand sperm each second versus the monthly female egg, making the male reproductive process harder to control. But researchers think they may have finally found a safe and simple means of temporarily stopping sperm production using a common clinical device: ultrasound.

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.

I think a careless male doctor or two would have realized this by now.. ha

It's pretty incredible and ironic if true, given that ultrasound is used to diagnose infertility problems. If this pans out, the safety of ultrasound will have to be reexamined. There are the studies suggesting it causes babies to be born left-handed (Kieler, et al., Epidemiology 2001;12:618-23), or see

Ultrasound scans may disrupt fetal brain development

I wonder when the scientists will realize that ultrasounds are actually harmful to people, including unborn fetuses!

We can build it - but should we?

Let's have a look at theforce behind of the birth control movement - Margaret Sanger. She served as president of International Planned Parenthood and was a eugenicist. She started the 'Negro Project' to purify the world of 'Negros' through birth control. She also advocated forced birth control to cleanse the world of disabled people.

So now there is a way to conveniently force sterilization on those 'inferior' 'non-white' people in third world countries.

Governments can and certainly will take control of a man's body and by extension his wife's. And of course there is no telling what horrible side effects will occur downstream when fertility resumes with such trauma to a fragile and complex reproductive system...

You also have to wonder why there is a huge cover-up of the simple fact that condoms do not prevent the transmission of venereal disease and HIV/AIDS. Condom latex has pores large enough for viruses to pass through. With this new technology, there will be no condom to even reduce the rates of infection. But it will serve the purpose of reducing third world populations.

Stateside, look at the huge increase in broken homes, single-parent families and gut-wrenching divorces. You have to wonder - is the modern sexual revolution making people happier?

While I think this is promising research that certainly merits continued study, what I really got from this article was that the study was funded by the Bill and Melinda Gates Foundation. In the past, they have spent much of their money on immunizations for children in 3rd-world countries. Then some people started to say that they were causing famines due to increased populations in these countries because the kids weren't dying of the diseases we have shots for. And now they are putting money into new forms of contraceptives. Ironic. :)

Don't get me wrong. They're great people, and have done a lot of good. I just thought it was interesting. =P

HazMatt - excellent observation. Good ole man's intervention in human evolution. I'm not touching Lucky's comment.

Terrible conversation to have though - let babies die due to disease or let them die due to overpopulation and famine. As for this situation of birth control - wow. I wonder if they could just have a group of people walk into a room, zap them with ultra sound and then radically control births. In "some" of those 3rd world countries the men refuse to wear condoms which is why there is such a massive educational effort underway on AIDS prevention. What if we had all those men walk into this room, zapped and then births for that village are down x-fold for the next 6 months.

Worse what if there's a hand held version of this out there.

Every form of birth control requires some sort of acceptance or willingness on the part of the individual (condoms or the pill etc...) This could actually be a way to do so without another person knowing. Wait, maybe I did just touch Lucky's comment?

Okay back to work...I digress.

so - a dose of ultrasound to the testicles will damage them enough to stop them from producing sperm for 6 months, but doing this to them 20 or 30 times won't damage them permanently? i sure hope it works, but i wouldn't want to be one of the men at the front of the line...

Wife yelling at husband is similar and well tested.

@lucky "there is a huge cover-up of the simple fact that condoms do not prevent the transmission of venereal disease and HIV/AIDS"

what cover-up. I agree that it is not very well advertised and many people who have been exposed to the ads don't fully grasp the info. Then there are people who actually know nothing and pass stupid info down to their kids which is dangerous. In no way though is there a cover-up. I see advertisements all the time stating they don't protect against diseases, including a sex ed seminar I had in elementary school. Which is odd because after the 4th grade, my schools never talked about sex again, but we went into some great detail back then. Last but not least, every box of condoms I have ever bought has written on the side does not protect against sexually transmitted diseases. sure its small like all warnings but its still there.

as for zapping myself with with this, no way. My junk isn't gonna near ultrasound devices except for when my wife is getting the ultrasound because we forgot a condom.

Saw this one coming!

Already they are sterilizing women against their will in Namibia:
