As temperatures soar, many are unaware of how much heat can quietly sabotage male fertility. While summer brings outdoor fun and sunny skies, it also poses hidden risks to sperm health. According to fertility experts, small lifestyle adjustments can make a significant difference in protecting and even boosting reproductive health during these hotter months. Read More
Dr. Prasanta Kumar Nayak, MBBS, MD-OBG, Clinical Head and Fertility Specialist at Oasis Fertility, Visakhapatnam, explained the overlooked connection between heat and sperm quality — and how men can turn summer into an opportunity rather than an obstacle for fertility. “Sperms require a conducive environment to thrive; the testicles function best at a temperature 2-3°C lower than the body,” said Dr. Nayak. Scientific research backs this up: According to the Iranian Journal of Public Health, for every 1°C rise in testicular temperature, sperm production drops by about 14%. Heat stress reduces both sperm motility and viability, highlighting why summer precautions are so crucial. Dr. Nayak outlined simple but effective strategies to guard sperm health during the summer season: With these lifestyle changes, men can help maintain optimal conditions for sperm health even during peak summer heat. Despite its risks, summer also offers unique advantages for reproductive health: Gentle sun exposure — especially during morning or late afternoon — stimulates vitamin D production, which plays a vital role in improving sperm quality, motility, and testosterone levels. Summer is the perfect time to load up on hydrating, antioxidant-rich foods. Fruits like watermelon, oranges, and berries, along with vegetables like cucumbers, support hydration and supply essential nutrients for reproductive health. Proper hydration also ensures optimal seminal fluid quality and sperm motility. “The summer season encourages outdoor physical activities such as swimming, walking, and cycling — all of which enhance blood flow and hormone regulation,” Dr. Nayak said. Longer daylight hours, natural sunlight exposure, and outdoor activity help regulate sleep patterns and reduce stress. Both factors significantly impact hormone balance and sperm health, making summer an opportune time for those undergoing fertility treatments. “Summer can be a chance to boost reproductive health, not a threat to it,” Dr. Nayak emphasized. With a few proactive steps, summer can be turned from a fertility challenge into a fertility ally. Maintaining smart habits through the season not only safeguards sperm health but also improves overall well-being, bringing couples closer to their dream of parenthood.
