Scientific studies show that on average, the testes are 2°C warmer when a man is seated rather than standing. It only takes a 1°C increase in testicular heat to reduce fertility by 14. and a 2-3°C increase in testicular heat can stop sperm production all together. How often are you seated?

Planning a family is one of the most exciting journeys any couple can go through. However, conceiving isn’t always easy and sometimes it can take longer than expected.

Infertility problems are often seen as a female issue, but men are a contributing factor in 50% of all infertility cases with sub-quality sperm being a leading cause of miscarriage.

While there are many factors that can affect male fertility scrotal/testicular heat plays a significant role in impacting male fertility especially today as we are living more sedentary lifestyles.

Scientific studies show that a 1ºC degree increase in testicular heat can reduce fertility by 14% and until now, there hasn’t been a practical or functional solution to decrease testicular heat that does not damage sperm health at the same time. Other “cooling underwear” is usually made from polyester which has now been found to damage and kill sperm cells.

Cool Beans Underwear has a unique, patented, scientifically designed mesh pouch that comfortably supports the testes and scrotum holding them away from the body. This allows them to self-regulate to 2-3°C cooler than the core body temperature, which helps to improve sperm health and male fertility. To maintain optimal sperm production, the testes need to be 3°C cooler than the body’s core temperature.

With Cool Beans Men’s Health Underwear your post-operative recovery time can be reduced, and discomfort kept to a minimum.

For post-operative care, doctors recommend keeping the anatomy elevated and supported after surgery as this will allow for decreased swelling and a faster recovery. 

Cool Beans’ patented design allows the scrotum and penis to rest and remain elevated with the aid of its external air-flow pouch and penis panel.

You should wear your Cool Beans for the first 5-7 days, even to sleep. This will keep the penis and scrotum held in place, helping to reduce swelling and allowing a comfortable night’s sleep. 

With Cool Beans Underwear it’s also easy and comfortable to apply an ice pack to either scrotum or penis, which is usually recommended in the days post-surgery.

Cool Beans

Improving sperm health and fertility for cyclists.

Cool Beans Men’s Health Underwear is entered into the TGA Register as a medical device. (ARTG 379655)

Cool Beans Men's Health Underwear helps prevent testicular damage and impaired testicular function for cyclists.

It has been proven through various scientific studies that men who cycle have a much higher infertility rate due to excessive heat absorption from the body’s core temperature caused by compression of the testes between the body and saddle, making cycling one of the worst sports for testicular and sperm health.  

Regular cyclists also run a higher risk of testicular damage and impaired testicular function due to scrotal compression and knocks to the scrotum.

Cool Beans Underwear’s patented ‘airflow pouch’ design keeps the scrotum held forward, so there is less compression of the testicles between the saddle and body and thus a reduction in the absorption of core body heat and a far more comfortable ride.

Whether you’re looking to  start a family or just to be more comfortable when cycling – Cool Beans Underwear are a must!
