Temperature is a significant determinant of male fertility, yet it is often overlooked. Both hot and cold extreme temperatures significantly impact sperm health, which is essential for a man to conceive. Nevertheless, fertility treatment is still possible in summer provided that proper control over it is exercised.
We spoke to Dr Prasanta Kumar Nayak, MBBS, MD-OBG, Clinical Head and Fertility Specialist, Oasis Fertility, Visakhapatnam, who explained the impact of heat on fertility health.
Impact of Temperature on Sperm Health
“Sperms require a conducive environment to thrive; the testicles function best at a temperature 2-3°C lower than the body. Excessive exposure to heat, hot tubs, tight clothing, or workplaces with high temperatures can harm sperm motility, quality, and DNA integrity,” said Dr Nayak. Men can protect fertility during summer months by making aware lifestyle modifications.
According to the Iranian Journal of Public Health, heat stress negatively affects human sperm by decreasing motility and viability. For every 1°C increase in testicular temperature, there is a 14% reduction in spermatogenesis.

How To Stay Cool During Summer to Protect Sperm Health?
The testicles function best at a temperature 2-3°C lower than the body's core temperature. With smart lifestyle habits, men can provide a conducive environment for sperm generation and quality even during summer. Follow these effective strategies shared by Dr Nayak:
- Wear Breathable Clothing: Choose loose-fitting, lightweight clothing like cotton and linen to allow air circulation and reduce heat buildup.
- Stay Hydrated: Adequate intake of water maintains body temperature and healthy seminal fluid, which is critical for sperm motility.
- Use Smart Cooling Techniques: Cooling the house with fans or low-temperature air conditioners avoids overheating but very low temperatures must be avoided to ensure healthy blood circulation.
- Take Cooling Showers: A cool shower reduces body temperature and avoids overheating after outdoor activity.
The Bright Side of Summer for Fertility
Boosting Vitamin D Levels
In the summer, being outside in natural sunlight stimulates the body’s production of vitamin D. This nutrient plays a crucial role in enhancing sperm quality, motility, and testosterone levels. Gentle sun exposure, especially in the morning or late afternoon, can be beneficial without the risk of overheating.
Seasonal Nutrition and Hydration
Consuming hydrating and antioxidant fruits and vegetables in the summer contributes to overall well-being, including fertility. Watermelon, cucumbers, oranges, and berries are a few foods that cool the body down while providing essential nutrients to the sperm. For maintaining seminal fluid in healthy form and keeping sperm motility at an optimum level, being well-hydrated is essential.
Offers an Active Lifestyle
“The summer season promotes outdoor exercise, such as swimming, cycling, and walking, each of which enhances blood flow and reproductive health. Regular exercise is needed to keep hormones in check and weight in hand, necessary for sperm production,” added Dr Nayak. Outdoor exercise in moderation, particularly during cooler periods of the day, enables the benefits of fresh air and exercise without overheating.
Better Sleep and Reduced Stress
Engaging in outdoor activities and sunlight exposure normalises sleep patterns, reduces stress, and increases overall well-being. Lower stress levels lead to better hormone balance and sperm health, and summer is therefore a good time of year for those receiving fertility treatment.
Message From The Expert
"Summer can be a chance to boost reproductive health, rather than a hindrance to fertility. The season naturally favours fertility with more vitamin D from the sun, improved circulation through exercise outdoors, and availability of hydrating, nutrient-dense foods, all of which lead to better sperm quality and overall reproductive health," said Dr Nayak.
Bottomline
Dr Nayak concluded, “Men can create a healthy environment for reproductive purposes by following effective lifestyle modifications, including the use of breathable clothing, keeping oneself hydrated, consuming antioxidant-based foods, and regular exercise. With the proper precautions in place, summer can actually promote fertility treatments and enhance outcomes as well as aid people in progressing towards their dream of parenthood.”
