There are several issues with traditional underwear and how sperm health is impacted.  In traditional underwear, the scrotum is held up next to the body, absorbing the body’s core temperature and, while seated, the scrotum is insulated by the thighs.  On average, the testes are 2°C warmer when seated than standing and a mere 1°C increase in testicular heat can decrease fertility by up to 14%.  Cool Beans has been designed with your testes in mind to ensure support and comfort, unlike traditional underwear, which only house the testes, a bit like a couples of peaches rolling around the car boot.

Our underwear has a patented design, with an entirely new structure and fit to any other underwear globally. With years of research put into the design we have the comfiest undies available on the market and is the world’s first scientifically designed underwear dedicated to keeping the testes at optimal temperature to improve sperm health, aiding in the treatment of skin conditions, assisting with post-operative recovery, and can enhance your aesthetics and confidence! Not your average underwear!

Many alternatives miss the mark on the science behind health underwear. For example, cooling underwear achieve a cooler environment for the testes by using polyester fabric. BUT Polyester has now been scientifically proven to interact with scrotal hairs causing an electrostatic field to be created, which causes microwaves to penetrate the testes, damaging and possibly killing sperm. Cool Beans is made from a bamboo/cotton/elastane composition and a nylon elastane mesh.

And besides, if you are serious about improving sperm health why would you compromise?

It takes on average 72 days for sperm to develop and mature. In order to create an optimal environment and allow sperm to mature, we recommend wearing Cool Beans for a minimum of 3 months prior trying to conceive with 4 months being optimal. Improving the environment within the testes does not happen immediately.

Simply, place a bank card under your scrotum (so one edge of the card is aligned with the edge of your scrotum). Next, refer to the diagram below. Depending on where the other side of your scrotum sits determines the pouch size suited to you.

Cool Beans Underwear can be washed as normal so no need for any special treatment. While line drying is ideal, Cool Beans is a cotton/bamboo blend and is easier to care for than bamboo underwear and can be tumble dried if required due to the added structural stability from the added cotton fibres.

When wearing Cool Beans Underwear, the testicles are held forwards from between the legs, so comfort is pretty much guaranteed. No more getting a little “caught” and trying to find a place to adjust yourself discreetly while avoiding embarrassment. Our early testers also noted that the overall presentation of the underwear when being worn was not only practical and comfortable but pleasing to the eye!
