3 habits impacting male fertility

In an Instagram post shared on September 29, Dr Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard and Stanford Universities, revealed the three everyday habits that may be worsening your fertility or causing fertility issues in males.

Sharing them, the expert wrote, “Surprising Male Fertility Killers You Should Be Aware Of. Did you know some everyday habits could be quietly harming fertility? Which one do you think is the most common?” Let's find out what these habits are:

1. Hot tubs and saunas

High temperatures from these can lower sperm count and quality because testicles need cooler temperatures to produce healthy sperm. A single prolonged exposure can impact sperm production for up to 3 months.

2. Tight underwears

Wearing tight underwear increases the heat around the testicles, which can negatively impact sperm production and quality over time.

3. Smoking and vaping

Smoking and vaping are not only injurious to your general health but also to your fertility. Both of these habits introduce harmful chemicals into your body that can reduce sperm quality and motility.
