A recent study by Calcutta University in collaboration with the Institute of Reproductive Medicine found a strong link between common tech habits—such as placing laptops directly on the lap or keeping mobile phones in front pockets—and a higher risk of male infertility.
The research, first reported by the Times of India, surveyed 1,200 men aged 20 to 40. It showed that over 50%—around 708 men—had azoospermia, a condition where no sperm is present in the semen.
Researchers also observed that many men with zero sperm count had a specific genetic mutation, which could be worsened by constant exposure to device-generated heat and electromagnetic fields (EMF).
“We are now beginning to see how environmental and tech-related lifestyle habits can combine with genetics to accelerate reproductive health issues,” said one of the lead researchers at Calcutta University, as quoted by The Times of India.
Risk Among Younger Men
The study revealed that men under 30 were more vulnerable, especially if they carried the identified gene mutation and were exposed to prolonged heat from devices.
This group was reportedly ten times more likely to experience azoospermia. These findings align with observations by Dr. Jesse Mills, Director of the Men’s Clinic at UCLA, who previously stated that even a 2–3°C increase in scrotal temperature over time can significantly impair sperm production.
Contradictory Global Evidence
While the Indian study presents compelling correlations, some international experts argue that evidence linking EMF exposure to infertility remains inconclusive.
A 2024 global meta-review cited by NDTV noted that multiple factors—such as diet, stress, and genetics—make isolating EMF effects difficult.
Nevertheless, doctors recommend minimizing direct exposure to electronic devices near reproductive organs as a precaution.
“This is a wake-up call for both men and women. With digital dependence rising, small changes in daily habits can help reduce risk,” said Dr. Sajal Gupta, a reproductive endocrinologist, to NDTV.
Impact on Female Fertility Also Suspected
The report also suggested that similar device-use patterns could pose risks to female reproductive health, potentially affecting ovarian function and hormonal balance.
However, this area remains under-explored and needs further study.
Recommendations for Digital Hygiene
• Avoid placing laptops directly on your lap; use a cooling pad or desk.
• Carry mobile phones in bags or upper pockets, away from the waist.
• Take regular breaks from extended tech use.
• Get fertility evaluations if exposed to such risk factors for extended periods.
Wider Public Health Relevance
The study comes amid rising cases of male infertility in India and could have significant implications for public health policy. As more people adopt always-on digital lifestyles, fertility experts emphasize the need for digital hygiene awareness campaigns and early diagnostics.
