An international team of researchers found a significant decline in sperm counts over the years in many countries globally, including India. The study was published in the journal Human Reproduction Update.

Sperm count is an indicator of human fertility and men′s health. Several studies have associated a lower sperm count with an increased risk of chronic disease, testicular cancer, and a decreased lifespan. For the study, data were collected from 53 countries over seven years, between 2011 and 2018.

The findings of the study showed an accelerated decline in the total sperm count (TSC) and sperm concentration (SC), globally. Dr. Hagai Levine, a professor at the Hebrew University of Jerusalem in Israel, stated that India is part of this global trend. He added that they came to their conclusion with the help of sufficient and good data. The data showed that India has experienced a strong and significant decline, similar to the global trend.

Dr. Levine explained that the current study did not examine the causes of the decline in sperm count. Disruptions in the development of the reproductive tract during fetal life, on the other hand, can be linked to lifetime fertility impairment and other markers of reproductive dysfunction. Additionally, he noted that improper lifestyle choices and chemicals in the environment are the major factors behind disturbed fetal development.
