Is it better to wear briefs or boxers for your testicles? The answer few people know.

Briefs: full support, but… too much heat

Briefs have always been a classic: compact, practical, with strong support.
However, they have advantages and disadvantages, these are the main ones:

• They offer good stability but tear quickly

• They fit easily under any type of trousers but not to the body

• They tend to compress the genital area

• They can retain heat and moisture

• After a few hours they no longer contain

The main problem? The temperature.
Science and elegance are at odds with this garment. In fact, to function properly, the testicles must remain slightly cooler than body temperature. Excessive compression and poor breathability in briefs can raise body temperature, creating discomfort or interfering with daily comfort.

Classic Boxers: Freedom, but Little Support

Loose-fitting, classic or American boxers, on the other hand, leave the genital area free to “breathe”.

• They offer more freshness and breathability

• They do not compress the testicles

• They lack support

• They can be uncomfortable during more dynamic movements

For many men, boxers are synonymous with freedom and comfort, but they aren't always the ideal solution for every everyday situation. They're elegant, yes, but definitely not comfortable.

What the studies say

Several scientific studies, including a study from the Harvard T.H. Chan School of Public Health , have observed that men who wear loose-fitting boxers tend to have slightly better semen parameters than those who wear very tight briefs.

However, it is important to clarify:

• the effects are modest in the general population,

• there is no universal “prescription”,

• comfort and breathability remain the most relevant factors in everyday choices.
