>> The technology of the COSO is based on a study of the Parsemus Foundation from 2012 in which successful research was conducted on ultrasound contraception.

Isn't that the same organization that has been claiming to bring RISUG to the US for the last 10 years with ZERO results? I'm starting to think they're actually a shill claiming to tackle this issue so that nobody else will. Their goal seem to be the opposite of what they say.

I'd love to have effective male contraception. But the previous work on this doesn't make it look like it's the answer: https://www.parsemus.org/humanhealth/ultrasound-male-contrac... See the section "Effective contraception in humans remains elusive"

Yeah, those numbers don't look good - 20% motility and 50% of normal count sounds like potential for pregnancy. Maybe reduced, but still there.

it's always a bad sign when the commercial slides and the nice 3D renders are ready before any scientific study of the device

The James Dyson award is a design award. On second view, this appears to be a master thesis project by a technical design student. So the product does not yet exist, and there are lots of problems with getting it there. I did not properly see all that before posting it; my apologies.

Nevertheless, it's an interesting idea to speculate about. And it seems to be one of the more promising ideas in this area.

In the past men used to take really warm baths to temporarily become infertile, i assume this uses the same process In related news: "coso" is used in italian to mean d.

To be fair, coso could be used to refer to any generic thing, male (in Italian language everything is male or female). Unfortunately given the context, this could only refer to that.

I see a couple of acceptance problems with the device. First, men a notoriously squeamish when it comes to their testicles. "Heating" without telling the temperature won't fly with many. I guess it doesn't have to be hot as it probably only needs to be warm enough to relax the cremaster muscles. If it has to be uncomfortably hot, I see little chance in the market. Second, I'd expect the ultrasound to hurt. The epidid…

Ultrasound treatments are actually used to treat pain.

Testicular ultrasound can hurt, but usually it's only an issue if there's an existing issue like infection or torsion.

4th, there's no data about return of fertility in humans after longterm use and if it raises birth defects.

Even so, providing direct control of fertility by a male partner is an important problem. Currently, the only control option that permits unprotected sex is a vasectomy -- this is expensive, requires many months, and is not always reversible. On the female side there is the UID and hormonal interventions -- both of which have downsides for the female partner.

I wonder how long the effect lasts? How often would a man have to do this to maintain continuous contraception? Seems like there might be some long term effects from repeated ultrasonic treatment of any human tissue.

How long but also how long does it take before the procedure is done and your sperm is sterile. Minutes? Hours? Days?

Why is it an important problem? We have hormonal and non-hormonal UIDs, many different types of pills, rings, and not to mention _condoms_ which actually prevents STDs. I don't have a problem with other guys heating their balls up, but where is the important problem?
