Male fertility is a growing concern worldwide, with male infertility playing a significant role in one in seven couples’ inability to conceive. In up to half of these cases, male factors contribute to reproductive challenges. Sperm health, a vital aspect of male fertility, is influenced by various lifestyle choices, diet, and environmental factors. Understanding these elements and adopting healthier habits can help improve sperm health and boost fertility.
Dr. Sabia Mangat, Consultant in Gynaecology and Reproductive Medicine at Milann Fertility Hospital in Chandigarh, emphasizes that men should be aware of the factors that impact their fertility. So, what makes sperm healthy?
Key Factors Affecting Sperm Health
According to Dr. Mangat, sperm health is determined by three critical factors: sperm quantity, motility, and morphology.
Sperm Quantity: A healthy semen sample contains at least 16 million sperm per milliliter, as per the World Health Organization (WHO) guidelines. Low sperm count can reduce the chances of conception, as fewer sperm are available to fertilize the egg.
Sperm Motility: The ability of sperm to swim through the female reproductive tract is crucial for successful fertilization. If more than 42% of sperm in the sample are moving, fertility is considered to be within a healthy range.
Sperm Morphology: A sperm cell consists of a head, midpiece, and tail, which aid its movement. A healthy sperm sample should contain at least 4% normal morphology to improve the chances of a healthy pregnancy.
Common Causes of Male Infertility
Several factors can reduce sperm quality and lead to infertility:
Obesity: Excess body fat disrupts hormone balance, particularly testosterone, which can impair sperm production and damage sperm DNA.
Substance Use: Smoking and the use of addictive substances such as alcohol and drugs can significantly lower sperm quality.
Genetic Factors: Deletions in the AZoospermia Factor (AZF) regions of the Y chromosome are linked to severe testicular dysfunction and infertility.
Health Conditions: Chronic conditions such as diabetes and sexually transmitted infections (STIs) like gonorrhea, chlamydia, and ureoplasma can also affect male fertility.
Environmental Factors: Prolonged exposure to high temperatures, such as in saunas or hot tubs, and professions requiring long sitting hours can negatively impact sperm production. Tight underwear and laptops kept on laps can also harm sperm health.
Age: Contrary to common belief, men’s reproductive capabilities decline with age. After 35, sperm quality starts to deteriorate, and by 40, the chances of fathering a child with genetic abnormalities increase significantly.
Medication and Supplements: Certain medications, including antidepressants and anti-androgens, as well as overuse of testosterone supplements and steroids, can impair sperm production.
How to Improve Sperm Health: Effective Lifestyle and Diet Changes
While male fertility may be impacted by various factors, making simple lifestyle changes and following a nutritious diet can help improve sperm count and overall fertility.
Lifestyle Modifications:
Maintain a Healthy Weight: A balanced body mass index (BMI) is linked to normal sperm count and motility.
Exercise Regularly: Moderate physical activity enhances fertility by improving blood circulation and hormone regulation.
Stress Management: High stress levels can negatively affect fertility. Practices like yoga, meditation, and deep breathing can help reduce stress and promote fertility.
Adequate Sleep: Aim for 7-8 hours of sleep per night to regulate hormone levels that influence sperm production.
Safe Sex Practices: Reducing the risk of sexually transmitted infections by limiting the number of partners and using protective barriers is essential for preserving fertility.
Quit Smoking: Smoking damages sperm DNA and significantly reduces fertility. Quitting can improve sperm health over time.
Nutritional Guidance:
Antioxidants: Foods rich in antioxidants, such as fruits, vegetables, and nuts, help combat oxidative stress and protect sperm health.
Omega-3 Fatty Acids: Found in fish, flaxseeds, and walnuts, Omega-3s promote sperm quality and motility.
Zinc: Zinc is vital for sperm production. Foods like oysters, beef, chicken, and pumpkin seeds are excellent sources of zinc.
Vitamin D: Adequate levels of vitamin D are essential for sperm motility. Sun exposure, supplements, or fortified foods can help maintain optimal levels.
Limit Processed Foods: High-glycemic foods and processed snacks can negatively affect fertility. A balanced, nutrient-rich diet is key.
Environmental Adjustments:
Avoid Harmful Toxins: Exposure to pesticides, heavy metals, and industrial chemicals can harm sperm health. Reducing contact with such toxins is crucial.
Limit Heat Exposure: Avoid excessive heat from saunas, hot tubs, and long hours in hot environments, as high temperatures can lower sperm production.
Minimize Radiation: Devices like mobile phones, laptops, and microwaves emit radiation that can impact sperm quality. Limiting their use, especially on the lap, can help protect fertility.
Conclusion
Improving male fertility is a multifaceted process that requires a holistic approach. By making lifestyle changes, adopting a healthy diet, and avoiding environmental hazards, men can significantly enhance their sperm health and fertility. If pregnancy has not occurred after a year of unprotected intercourse, consulting a fertility specialist can help identify underlying issues and provide treatments to support your journey to parenthood.
