India's fertility rate dropped from nearly 6.2 in 1950 to just under 2 in 2021, and is projected to fall further to 1.29 and 1.04 in 2050 and 2100, respectively, according to a new global research published in The Lancet journal. These numbers were found to be in line with global trends, where the Total Fertility Rate (TFR) was over 4.8 children per woman in 1950 and fell to 2.2 children per woman in 2021. These figures have been projected to fall to 1.8 and 1.6 in 2050 and 2100, respectively. The study found that there were 12.9 crore livebirths the world over in 2021 -- an increase from roughly 9.3 crore in 1950, but a decline from the peak of 14.2 crore in 2016. In India, there were more than 1.6 crore and over 2.2 crore livebirths in 1950 and 2021. The number is projected to fall to 1.3 crore in 2050. However, even as much of the planet contends with the challenges of low fertility, many low-income countries will still be facing high fertility issues during the 21st century, sa

An international team of researchers has found a significant decline in sperm counts over the years in many countries globally, including India. Sperm count is not only an indicator of human fertility but also that of men's health, with low levels being associated with increased risk of chronic disease, testicular cancer and a decreased lifespan, the researchers said. The decline reflects a global crisis related to modern environment and lifestyle, with broad implications for the survival of the human species, they said. The study, published on 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 not reviewed previously, specifically South America, Asia and Africa. The data shows, for the first time, that men in those regions share the significant decline in total sperm counts (TSC) and sperm concentration (SC) seen previously in Nort
