Male fertility is a topic that many men don’t often talk about, but it’s more important than ever to understand what affects it. In a recent video, Harvard doctor Saurabh Sethi shared three surprising habits that could be quietly reducing sperm count and affecting overall reproductive health. The insights are simple, practical and backed by science.
Three Surprising Habits That Harm Male Fertility And Reduce Sperm Count
Hot Tubs And Saunas
The first factor Dr Sethi highlights is exposure to high heat, such as in hot tubs and saunas. While relaxing, these environments raise the temperature around the testicles, which naturally need cooler conditions to produce healthy sperm.
According to the video, even a single prolonged session in such heat can affect sperm production for up to three months. It’s a simple reminder that what feels good in the moment can have longer-term effects on male fertility.
Tight Underwear
Next on the list is wearing tight underwear. While it might seem harmless, prolonged use can increase heat around the testicular area, just like hot tubs or saunas. Over time, this can gradually lower sperm count and reduce sperm quality. Dr Sethi advises men to opt for looser, breathable options to give the testicles the environment they need for optimal sperm production.
Smoking And Vaping
The third habit affecting sperm count is smoking and vaping. Both introduce harmful chemicals into the body that can damage sperm. These chemicals reduce sperm quality and motility, making it harder for sperm to function effectively. Dr Sethi explains that cutting down or quitting these habits can significantly benefit male fertility.
The video is direct and easy to understand. Dr Sethi breaks down each habit and explains the science behind it in clear, simple terms. All three factors (heat exposure, tight clothing, and harmful chemicals) have a common effect. They either raise the temperature around the testicles or introduce substances that interfere with healthy sperm production. Small lifestyle changes can have a big impact on male fertility and overall reproductive health.
By being aware of these everyday risks and making smarter choices, men can protect their sperm count and support long-term reproductive health.
