Male infertility is a growing concern around the world. It affects not only a man’s ability to have children but also his self-esteem and emotional well-being. Many people often believe infertility is a woman’s issue, but men account for nearly half of all infertility cases globally.
Luckily, many of the causes of male infertility are preventable. From lifestyle habits to environmental exposures, avoiding certain behaviors can improve fertility and boost reproductive health.
Here are 10 things men should avoid to reduce their chances of suffering from infertility.
1. Avoid Excessive Heat to the Testicles
High temperatures can negatively impact sperm production. Men who frequently use hot tubs, saunas, or sit for long periods with laptops on their laps expose their testicles to excessive heat, which may lower sperm count and quality. Wear breathable underwear and take breaks from prolonged sitting to protect your reproductive organs.
2. Say No to Smoking
Smoking cigarettes is one of the most harmful habits for overall health, and it has a direct impact on sperm health. Cigarette smoke contains harmful toxins that reduce sperm count, motility, and morphology. Studies show that male smokers are more likely to suffer from DNA-damaged sperm, which can lead to infertility or increase the risk of miscarriage and birth defects.
3. Limit Alcohol Consumption
Moderate to heavy alcohol use can reduce testosterone levels and interfere with the body’s ability to produce healthy sperm. Alcohol also affects the liver and overall hormone balance. Men who are planning to conceive should limit their alcohol intake or avoid it completely for improved reproductive health.
4. Stop Using Recreational Drugs
Drugs like marijuana, cocaine, and anabolic steroids can have damaging effects on fertility. Steroids, in particular, reduce the natural production of testosterone, which can lead to low sperm count or even a complete absence of sperm (azoospermia). Avoiding recreational drugs is essential for any man looking to maintain healthy fertility.
5. Be Mindful of Medications
Certain prescription medications can interfere with sperm production or hormonal balance. Examples include chemotherapy drugs, some antibiotics, and antidepressants. Men who are on long-term medications and are planning to start a family should speak with their doctor to explore safer alternatives or adjust dosages if necessary.
6. Watch Out for Stress
Chronic stress can disrupt hormone levels, including those responsible for sperm production. High-stress levels also impact libido and can lead to erectile dysfunction. Practice stress-reducing techniques like exercise, meditation, deep breathing, or hobbies to support emotional and reproductive health.
7. Maintain a Healthy Weight
Obesity in men has been linked to reduced fertility. Excess fat can lead to hormonal imbalances, lower testosterone levels, and higher estrogen levels—all of which negatively impact sperm production. On the other hand, being underweight can also harm fertility. A balanced diet and regular exercise help maintain a healthy weight and support reproductive function.
8. Avoid Exposure to Environmental Toxins
Certain environmental pollutants and chemicals found in pesticides, plastics (like BPA), paints, and heavy metals (lead, mercury) can harm sperm production. Men working in industries such as agriculture, construction, or manufacturing should wear protective gear and reduce direct contact with toxic substances whenever possible.
9. Limit Use of Lubricants and Chemicals During Intercourse
Some personal lubricants contain chemicals that can damage sperm or reduce their motility. When trying to conceive, it’s best to use sperm-friendly lubricants or natural alternatives like coconut oil (only if it doesn’t cause irritation). Always read labels and avoid products with harmful additives.
10. Don’t Ignore Regular Health Checkups
Underlying health conditions such as diabetes, thyroid disorders, infections, or varicocele (enlarged veins in the scrotum) can affect male fertility. Regular health checkups can detect these issues early and allow for prompt treatment. If you’ve been trying to conceive without success for over a year, consult a fertility specialist.
Bonus Tips for Boosting Male Fertility

Male infertility can be a sensitive and stressful issue, but the good news is that many causes are preventable and reversible. By avoiding these 10 harmful habits and embracing a healthier lifestyle, men can significantly boost their fertility and increase the chances of starting or growing their families. Remember, good reproductive health starts with good overall health.
For those facing persistent fertility challenges, consulting a medical professional is the best step. Early intervention and awareness can make a world of difference.
