global male sperm count is in crisis
A man from the Netherlands has violated regulations by donating sperm rampantly and has become the “father” of at least 550 children. Recently, this topic made headlines. However, prior data shows that the global male sperm count has been continuously decreasing. Studies have shown that in the past 50 years, the decline in male sperm count has exceeded 60%, with a decrease of more than half. This research indicates that not only aging, but also the continuous decline in the quality and quantity of sperm pose a threat to human society.
