Over the years, an international team of researchers discovered a significant decline in sperm counts in many countries worldwide, including India.
Sperm count is an indicator not only of human fertility, but also of men’s health, with low levels associated with an increased risk of chronic disease, testicular cancer and a shorter lifespan, the researchers said.
The decline reflects a global crisis related to the modern environment and lifestyle, with broad implications for the survival of the human species, they said.
The study, published Tuesday in the journal Human Reproduction Update, used data from 53 countries. It spans another seven years of data collection (2011-2018) and focuses on trends in male sperm counts in previously unassessed regions, particularly South America, Asia and Africa.
The data shows for the first time that men in those regions share the same significant drop in total sperm count (TSC) and sperm concentration (SC) previously seen in North America, Europe and Australia.
The study shows an accelerated decline in TSC and SC after 2000 worldwide.
“India is part of this larger trend. In India, due to the availability of good data (including 23 estimates in our study, one of the countries with the richest data), we have more certainty that there is a strong and sustained decline, but it is comparable globally,” Professor Hagai Levine of the Hebrew University of Jerusalem in Israel told PTI. has accelerated in recent years,” Levine said.
While the current study did not examine the causes of the decline in sperm count, Levine pointed to recent research showing that disturbances in reproductive tract development during fetal life are associated with lifelong impairment of fertility and other markers of reproductive dysfunction. dysfunction.
“In addition, lifestyle choices and environmental chemicals negatively impact this fetal development,” Levine explained.
“Our findings serve as a canary in a coal mine. We have a serious problem that, if left unsolved, could threaten the survival of humanity.
“We call for urgent global action to promote healthier environments for all species and reduce exposures and behaviors that threaten our reproductive health,” Levine said.
The scientist noted that a separate study should be done in India, better tracking the same population over time.
“However, there is no reason to believe that the trend is different in India,” he added. Professor Shanna Swan of the Icahn School of Medicine, Mount Sinai, USA, highlighted that low sperm count not only affects male fertility, but has serious implications for men’s health in general, and is linked to other adverse trends, collectively referred to as testicular dysgenesis. syndrome.
“The troubling declines in men’s sperm concentration and total sperm count of more than 1 percent per year reported in our paper are consistent with adverse trends in other men’s health outcomes, such as testicular cancer, endocrine dysregulation, and genital birth defects. decline in female reproductive health,” Swan added
