New Delhi: An international team of researchers has found a significant decline in sperm count in several countries globally, including India, over the past few years. The researchers said that sperm count is an indicator not only of human fertility, but also of men’s health, with low levels being associated with an increased risk of chronic disease, testicular cancer and a decreased lifespan. He said the decline reflects a global crisis related to the modern environment and lifestyle, which has wide-ranging implications for the survival of the human species.
The study, published Tuesday in the journal Human Reproduction Update, used data from 53 countries. It includes an additional seven years of data collection (2011–2018) and focuses on sperm count trends among men in regions that had not previously been reviewed, notably South America, Asia and Africa. The data show for the first time that men from those regions share a significant decline in total sperm count (TSC) and sperm concentration (SC) previously observed in North America, Europe and Australia. The study shows a rapid decline in TSC and SC globally after 2000.

“India is part of this larger trend. In India, because of the availability of good data (one of the data-richest countries, including 23 estimates in our study), we have more certainty that there is a strong and lasting decline, but it is similar globally,” Hagai Levin, a professor at the Hebrew University of Jerusalem in Israel, told PTI. “Overall, we are seeing a global decline of more than 50 percent in sperm counts over the past 46 years,” Levine said. This decline has accelerated in recent years.”
While the current study did not examine the reasons for the decline in sperm count, Levine pointed to recent research indicating that disturbances in reproductive tract development during fetal life may lead to a lifelong loss of fertility and fertility. associated with other markers of disability. “Additionally, lifestyle choices and chemicals in the environment are adversely affecting the development of this fetus,” Levine explained. “Our findings serve as a canary in the coal mine. We have a serious problem on our hands that, if not mitigated, could threaten the very existence of the human race.” That poses a threat to our reproductive health, Levine said. Added.
Professor Shanna Swann at the Icahn School of Medicine, Mount Sinai, US, stressed that low sperm count not only affects men’s fertility, but has more serious implications for men’s health, and more than other adverse trends. are associated, which together are called testicular disease. syndrome. “The troubling declines in men’s sperm concentration and total sperm count by more than 1 percent each year, as reported in our paper, are consistent with adverse trends in other men’s health outcomes, such as testicular cancer, hormonal disruption, and genital birth defects, as well as a decline in female reproductive health,” Swan said.
