Humans could become extinct if sperm counts in men continue to fall at current rates, a doctor has warned.
Scientists have raised the alarm over claims of possible human extinction if sperm counts continue to drop as fast as they have done in the last four decades in Western countries.
These are the findings of a new study published by ‘Human Reproduction Update’.
The researchers behind the study are from the Hebrew University-Hadassah Braun School of Public Health and Community Medicine and the Icahn School of Medicine at Mount Sinai in Isreal.
They claimed that Western lifestyle has more than halved the sperm count of men in the United States (U.S), Europe and Australia since the 1970s.
Sperm count is a measure of the number of spermatozoa per ******** or per measured amount of semen, used as an indication of a man’s fertility.
According to the lead author of the study, Dr. Hagai Levine, Sperm count is the best measure of male fertility.
He asserted that the findings are an ‘urgent wake-up call’ to investigate lifestyle factors, chemicals, and environment that could cause the human species to go extinct.
“If we will not change the ways that we are living and the environment and the chemicals that we are exposed to, I am very worried about what will happen in the future,” he said.
“Eventually we may have a problem, and with reproduction in general, and it may be the extinction of the human species.”
The study found 59.3 per cent average decline in total sperm count and a 52.4 per cent average decline in sperm concentration among these men.
The men researched in those studies were not chosen for the studies based on their fertility status.
