Can the Use of Laptop Cause Infertility?

The Covid-19 pandemic brought significant societal changes, including a rise in remote work. Many professionals, especially men, have continued to work from home in various countries. However, few are aware that prolonged use of electronic devices can negatively impact male fertility. Could placing a laptop on your lap for long periods contribute to infertility?

Impact on Sperm Production

According to Dr. Isabel de Almeida, coordinator of the Fertility Center at Hospital Moinhos de Vento, sperm production—known as spermatogenesis—occurs more efficiently when the temperature of the testicles is about two degrees below body temperature. Prolonged use of heat-generating devices, such as laptops, raises the temperature of the scrotal area, which can harm sperm production. This may reduce the quantity and quality of sperm, even causing DNA damage.

Other Sources of Heat and Their Effects

The issue is wider than electronics. Activities that increase heat in the scrotal region, like saunas, hot tubs, and even cycling, can affect sperm quality. Dr. Isabel advises that men avoid using laptops on their laps and take frequent breaks to move around rather than remain seated for long periods in the same position.

Lifestyle Matters, Too

In addition to heat, several lifestyle factors can impact male fertility. Obesity, lack of exercise, poor diet, alcohol consumption, and smoking are all associated with reduced sperm counts. Obesity, in particular, causes metabolic changes that lower testosterone levels and increase scrotal temperature. Sexually transmitted infections (STIs) are another concern, as they can lead to testicular infections, further affecting sperm quality.

Preventive Care: A New Focus for Men

Dr. Isabel highlights the importance of men undergoing regular check-ups to monitor their reproductive health, much like women do with their routine gynecological visits. Male infertility accounts for approximately 40% of cases among couples seeking treatment. This emphasizes the need to include semen analysis as part of initial infertility investigations, a practice that was once rare.

Prevention and Overall Health

The expert stresses that addressing environmental factors and lifestyle choices improves male reproductive health and enhances overall well-being. Preventive care and medical follow-ups are essential to maintaining fertility and ensuring broader health benefits, especially in a world where modern lifestyles may pose additional risks.
