How to choose mens underwear scientifically
The Hidden Risks of Mens Underwear
Boxers can be bad, especially for sports, due to loose fitting leading to chafing. Testicular torsion is also a concern for athletes, as strenuous exercise can cause the testicle to rotate on the cord. This happens due to a lack of support for down under.
Traditional briefs and boxer briefs offer support and are less prone to bunching. However, they are restrictive and don’t allow body heat to escape–heat retention.
Universities research related to men’s underwear and men’s health.

Oxford Textbook of Medicine Page 282 states: ‘The lower temperature in the scrotum is a prerequisite for normal spermatogenesis’. Harvard University Associate Professor Jorge Chavarro found: ‘Beyond providing additional evidence that underwear choices may impact fertility, our study provides evidence, for the first time, that a seemingly random lifestyle choice could have profound impacts on hormone production in men at both the level of the testis and the brain’.
University of Wisconsin announced: ‘Heat can reduce sperm count and testosterone production‘. Researchers from University of Buffalo found Male Obesity Linked to Low Testosterone Levels. Moreover, The University of Edinburgh found Low testosterone levels linked to diabetes.

The Solution: Patented “Chimney Effect” Design
To bridge the gap between support and cooling, the Aircon and Mr. Right range utilizes a patented airflow system. Unlike standard underwear, these are engineered with a “chimney effect” to naturally vent heat.

Key Features for Men’s Health:
- Strategic Ventilation: Mesh zones are placed in high-sweat areas to promote airflow and reduce body odor.
- Moisture Management: By preventing moisture build-up, this design reduces the risk of fungal infections and skin irritation.
- Premium Materials: Choose between 95% high-grade cotton or advanced quick-dry stretch fabrics for maximum support without the heat trap.
How Men’s Underwear Affects Future Generations
A father’s sperm health at the time of fertilization is a major factor in the health and intelligence of his children.
- Sperm Quality and Quantity: Maintaining a cool environment ensures the “natural selection” of the strongest, healthiest sperm.
2. Epigenetic Benefits: Scientists at the University Hospital Zurich found: ‘males who spend time in low temperatures prior to mating will produce offspring with more active brown adipose tissue…the offspring of males kept in cool conditions were better protected against excess weight—they gained less weight on a high-fat diet—and against metabolic disorders.’
3. Avoiding Risks: Researchers from King’s College London’s Institute of Psychiatry found “IVF for male infertility linked to increased risk of intellectual disability and autism in children”.
Why is it so important to stay about 2 °C cooler for down under?
Some people may think that a change of only 2 °C is insignificant, but its effects can be profound and far-reaching.For example, consider the difference between 2°C water and 0 °C water. At 0 °C, water reaches its freezing point and changes state, turning into solid ice. The same principle applies to the human body:
When your body temperature is around 37 °C, you are most likely healthy and functioning normally. If your temperature rises to 39 °C, you have a fever, you have difficulty to drive and think.
Even such a slight difference of temperature can have dramatic, profound consequences.
‘This is why the scrotum is located outside of the body.’

Make the Strategic Choice for Your Health
Your underwear is the most important piece of clothing you wear, you maybe wearing more than 23 hours per day, everyday. Switching to a design that prioritizes men’s health is a game-changer for your energy, hormone levels, and future family.
