Health Benefits
How SoJ's will boost your health.
Unlike tight underwear that can restrict blood flow, cause friction, and trap heat, wide boxers give your body the space it needs to breathe. Studies have also found that men who wear looser-fitting underwear, like wide boxers, tend to have better fertility outcomes compared to those who wear tight styles. The relaxed fit supports natural movement, helps regulate temperature, and reduces unnecessary pressure - prioritising both comfort and long-term health.
Your health starts below the belt.
Multiple studies have shown that wearing loose-fitting underwear, like SoJ boxershorts, supports male reproductive health. A landmark 2018 study from the Harvard T.H. Chan School of Public Health found that men who regularly wore boxers had 25% higher sperm concentrations and 17% higher total sperm counts than those who wore tighter underwear.
The reason behind this.
Temperature regulation. An earlier study published in the British Journal of Urology demonstrated that wearing boxers can lower deep scrotal temperature by up to 0.5°C compared to tighter styles. Since elevated temperature is known to impair sperm production, that seemingly small difference can have a big impact. At Son of John, our boxers are designed not only for timeless comfort - but for your long-term wellbeing.
