There is no clear consensus on whether boxers or briefs are more beneficial for penile and testicular health. Some studies have suggested that wearing loose-fitting boxers may help to reduce heat and moisture around the pelvic area, which may potentially reduce the risk of male infertility caused by high testicular temperature. However, other studies have found little evidence to support this idea.
On the other hand, wearing snug-fitting briefs or other types of undergarments may help to provide additional support to the scrotum, which could reduce the risk of testicular torsion. This condition occurs when one or both testicles twist within the scrotum, causing pain and, in some cases, damage to the testicular tissue.
Ultimately, wearing boxers or briefs is a personal preference and each individual may find that one style is more comfortable than the other. Regardless of the type of underwear, it is important to choose breathable, moisture-wicking fabrics and to avoid undergarments that are too tight or restrictive. If you have specific concerns about your penile or testicular health, it may also be helpful to speak with a healthcare provider.
