However, recent research has shed light on an unexpected aspect of this decision – its potential impact on sperm count and overall fertility. In this article, we will explore the differences between mens boxer briefs and mens boxers and how they may affect sperm count. While the topic may seem unconventional, it’s important for men to understand how their underwear choices can influence their reproductive health.

The Basics: Boxer Briefs vs. Boxers

Let’s define what makes boxer briefs different from boxers before we talk about the effect on sperm count.

Boxer Briefs:

1. Boxer briefs are snug-fitting underwear that extends down the thigh.

2. They offer support and hold the genital area in place.

3. The elastic waistband provides a secure fit around the waist.


1. Boxers are loose-fitting, resembling shorts.

2. They offer a relaxed and airy feel, allowing more freedom of movement.

3. Boxers typically have a non-restrictive waistband.

Let’s look at how the sperm count may change considering each of these variations.

Temperature Matters

One of the key factors influencing sperm production is temperature regulation. The testicles, where sperm is produced, are designed to be slightly cooler than the rest of the body. The scrotum, which holds the testicles, can adjust its position to help regulate temperature. This natural cooling mechanism is crucial for maintaining healthy sperm production.

Boxer Briefs and Sperm Count

Wearing boxer briefs that fit tightly can offer support to the scrotum and keep it close to the body. However, this can sometimes increase the temperature around the testicles, which may affect sperm production. When the scrotal temperature is elevated, even by a few degrees, it can lead to a decrease in sperm count and reduced sperm motility.

Research has revealed that wearing boxer briefs for prolonged periods might result in a slight decrease in sperm count. It’s essential to understand that this impact differs from person to person. Certain men may encounter more noticeable temperature-related alterations than others.

Boxers and Sperm Count

On the other hand, boxers, with their loose-fitting design, allow the scrotum to hang freely away from the body. This can promote better air circulation and help maintain a cooler temperature in the testicular region. Cooler temperatures are generally considered more favorable for healthy sperm production.

Research suggests that men who prefer boxers may experience a slightly higher sperm count compared to those who opt for snug-fitting boxer briefs. However, the difference in sperm count between the two underwear styles is typically not substantial and may not be the sole determinant of fertility.

Other Factors to Consider

While underwear choice can influence sperm count to some extent, it’s important to remember that fertility is a complex issue influenced by various factors. Here are a few additional considerations:

1. Lifestyle and Diet

The quality and quantity of sperm are more significantly influenced by exposure to environmental toxins, dietary habits, and level of physical activity compared to the choice of undergarments worn.

2. Genetics

It is possible that some men may have a naturally lower sperm count due to genetic factors, regardless of their preference for underwear.

3. Habits

Engaging in habits like smoking, excessive alcohol consumption, and drug use can harm male reproductive health, causing fertility issues and other complications.

4. Age

As one gets older, their sperm count tends to decrease, which ultimately affects fertility.


The decision between boxer briefs and boxers can have a minor effect on sperm count, but it is only a small aspect of the broader fertility puzzle. The impact of underwear choice on sperm count differs from person to person, and other lifestyle factors have a more significant impact on overall reproductive health.

If you are worried about your fertility or sperm count, it is recommended that you speak with a healthcare professional. They can provide personalized guidance and perform tests to ensure your reproductive health is thoroughly assessed.

In conclusion, the debate on whether boxer briefs or boxers have an impact on sperm count remains ongoing. But it’s crucial to prioritize your overall health and well-being when choosing underwear that could potentially affect your fertility. Instead of solely focusing on fertility concerns, select underwear based on your personal comfort and preference. It’s important to remember that fertility is a complex issue, and maintaining a healthy lifestyle is vital for optimal reproductive health.
