Sperm count decline

Topic

Sperm count decline refers to the observed global decrease in human sperm concentration and total sperm count since the mid-20th century, often discussed as a male infertility crisis. Meta-analyses indicate that sperm counts have declined significantly in both Western and non-Western countries, prompting research into environmental, lifestyle, and chemical factors. While the trend has garnered widespread scientific and media attention, some researchers debate the severity and methodology of the findings.
