ARE YOU INTERESTED in trying a novel male contraception that zaps sperm to prevent pregnancy?

A new bath-like device that heats the testicles and reduces sperm motility is based on this principle.

According to the designers, this should prevent pregnancy and is reversible in just a few months, allowing for family planning.

The notion has only been tested on animals so far, but it is hoped that it will soon be applied to humans.

As the search for a male alternative to the Pill, coil, and implant continues, designer Rebecca Weiss hopes it will revolutionize contraception.

“The device is filled with water and immediately warmed up to operational temperature,” she added of COSO.

“The therapy is given while sitting with the legs spread apart.

“The sensation will be similar to that of a warm bath because the water temperature is only slightly over body temperature.”

“The testicles are placed inside and subjected to ultrasonic testing for a few minutes.

“The ultrasound causes the testicular tissue to heat up deeply.”

“By altering sperm motility, this focused application of heat stops the female egg from being fertilized.”

“In addition, for a period of time, the creation of fresh sperm is inhibited.

“As a result, a consistent contraceptive effectiveness is established.”

A doctor would configure the device before it was used for the first time to suit the user’s testicle shape and size.

It can be utilized at home after it is up and running. It would be used to provide two fifteen-minute treatments separated by two days.

The contraceptive should be effective after two weeks and last for at least two months.

A COSO app, which can be shared with a partner, would log treatments and notify men when it was time to use the device again.

Fertility should return to normal six months following the final treatment, according to experts.

The research is still “hypothetical,” according to the COSO website, because it hasn’t been demonstrated to stop pregnancies in humans.

Its effectiveness is unknown, but it would have to match the 99 percent and higher success rates of condoms, the Pill, and other methods to be regarded trustworthy by consumers.

However, studies have shown that when testes are exposed to high temperatures, such as those found in hot tubs, saunas, and laptops, sperm counts can temporarily drop.

Rebecca, from Munich, Germany, claims that the science behind her proposal has been verified on animals, and she now seeks to get her design clinically evaluated on humans.

The final release date will be determined by the findings of such a clinical trial, but she anticipates “significant milestones” in the next two to three years.

“The pricing is heavily influenced by whether COSO is classified as a medical or non-medical equipment,” she explained.

“As a consumer product,…
