Male infertility is a growing concern worldwide, with lifestyle factors playing a significant role. For couples struggling to conceive, male factors are contributors in approximately 50% of cases.
AIIMS, Harvard, and Stanford-trained gastroenterologist Dr. Saurabh Sethi has highlighted three surprising daily habits that many men regularly engage in, unknowingly harming their fertility.
Infertility is defined as the inability to achieve a pregnancy after 12 months of unprotected intercourse. Research indicates a progressive decline in sperm quality globally, including reductions in sperm concentration, motility, and morphology . Understanding and modifying certain daily habits can be a powerful step toward improving reproductive health.
· Alcohol Consumption: Regular alcohol intake can negatively affect sperm quality. A study in BMJ Open found that even as little as five drinks per week could reduce sperm quality, with worsening effects at higher consumption levels.
· Obesity: Maintaining a healthy weight is crucial. Obesity (a BMI over 30) can cause hormonal imbalances and increase oxidative stress, leading to reduced semen parameters. One study showed obese men were three times more likely to have a reduced sperm count.
· Mobile Phone Use: There is growing concern about electromagnetic radiation from devices like mobile phones, especially when carried in trouser pockets. Some meta-analyses have reported that exposure from phones is linked to a reduction in sperm motility and viability.
· Poor Diet and Lack of Exercise: A diet high in processed meats, saturated fats, and sugar can harm semen quality. Conversely, a diet rich in antioxidants, whole grains, and vegetables supports cellular health. Moderate exercise is beneficial, but excessive, intense cycling should be approached with caution as it can increase scrotal temperature.
· Limit heat exposure to the scrotal area.
· Quit smoking and vaping.
· Reduce or eliminate alcohol consumption.
· Achieve and maintain a healthy weight through a balanced diet and regular, moderate exercise.
· Eat a nutrient-dense diet with adequate protein and antioxidants.
If you are struggling to conceive, consulting a healthcare provider is essential. They can perform a proper evaluation, such as a semen analysis, and provide personalized guidance. For men aged 35 and over, it is advisable to seek help after six months of unsuccessful attempts, while those under 35 should consult a doctor after one year.
The content presented, which discusses potential factors affecting male fertility, is based on a synthesis of public information and general medical knowledge. It is not an exhaustive list, and individual causes of infertility can vary significantly.

AIIMS, Harvard, and Stanford-trained gastroenterologist Dr. Saurabh Sethi has highlighted three surprising daily habits that many men regularly engage in, unknowingly harming their fertility.
Infertility is defined as the inability to achieve a pregnancy after 12 months of unprotected intercourse. Research indicates a progressive decline in sperm quality globally, including reductions in sperm concentration, motility, and morphology . Understanding and modifying certain daily habits can be a powerful step toward improving reproductive health.
The Three Detrimental Habits for Male Fertility
1. Frequent Use of Hot Tubs and Saunas
Prolonged exposure to heat from hot tubs and saunas can negatively impact sperm count and quality. Healthy sperm production requires the testes to maintain a temperature slightly lower than the core body temperature. The heat from these sources can raise the scrotal temperature, disrupting sperm production. Studies have shown that activities which increase scrotal temperature, like long hot baths, are associated with sperm health issues. It's important to note that the effects on sperm production can last for up to three months.2. Wearing Tight Underwear
Similar to using hot tubs, regularly wearing tight underwear can be harmful because it increases heat around the testes. This habit can elevate scrotal temperature over time, which may lead to reduced sperm production and quality. Opting for looser-fitting underwear can help maintain a cooler, more optimal environment for sperm health.3. Smoking and Vaping
Smoking traditional cigarettes and e-cigarettes is detrimental to overall health and male fertility. These products introduce harmful chemicals into the body, which can damage sperm DNA and reduce sperm quality. Research published in the BJU International journal found that smokers' sperm had irreparable DNA damage, limiting the chances of normal fertilization and a healthy pregnancy. A 2024 review also confirmed that cigarette smoking significantly contributes to the deterioration of sperm quality.Other Significant Lifestyle Factors That Affect Fertility
Beyond the three habits highlighted by Dr. Sethi, extensive research links several other modifiable lifestyle factors to male infertility:· Alcohol Consumption: Regular alcohol intake can negatively affect sperm quality. A study in BMJ Open found that even as little as five drinks per week could reduce sperm quality, with worsening effects at higher consumption levels.
· Obesity: Maintaining a healthy weight is crucial. Obesity (a BMI over 30) can cause hormonal imbalances and increase oxidative stress, leading to reduced semen parameters. One study showed obese men were three times more likely to have a reduced sperm count.
· Mobile Phone Use: There is growing concern about electromagnetic radiation from devices like mobile phones, especially when carried in trouser pockets. Some meta-analyses have reported that exposure from phones is linked to a reduction in sperm motility and viability.
· Poor Diet and Lack of Exercise: A diet high in processed meats, saturated fats, and sugar can harm semen quality. Conversely, a diet rich in antioxidants, whole grains, and vegetables supports cellular health. Moderate exercise is beneficial, but excessive, intense cycling should be approached with caution as it can increase scrotal temperature.
Positive Steps You Can Take
The good news is that these lifestyle factors are modifiable. Sperm take about 74 days to mature, meaning positive changes can lead to improvements in sperm quality within approximately three months . Key actions include:· Limit heat exposure to the scrotal area.
· Quit smoking and vaping.
· Reduce or eliminate alcohol consumption.
· Achieve and maintain a healthy weight through a balanced diet and regular, moderate exercise.
· Eat a nutrient-dense diet with adequate protein and antioxidants.
If you are struggling to conceive, consulting a healthcare provider is essential. They can perform a proper evaluation, such as a semen analysis, and provide personalized guidance. For men aged 35 and over, it is advisable to seek help after six months of unsuccessful attempts, while those under 35 should consult a doctor after one year.
