Summary of Human fertility threat
A study conducted in Denmark from 2017 to 2022 revealed a significant decline in sperm motility among sperm donors, with a 22% reduction by 2022.
The decline in sperm motility raises concerns about human fertility and the future of the human race.
The study involved analyzing semen quality among men applying to be sperm donors, with a focus on sperm concentration and total motile sperm count.
The study did not determine the cause of the decline in semen quality from 2019 to 2022.
Urgent research is needed globally to gather health and lifestyle data on sperm donors and identify causal factors for the decline in sperm quality.
The study authors emphasize the importance of addressing the decline in sperm quality to ensure human fertility.
The study was conducted by researchers from Denmark, Canada, and the UK.
