Sperm counts Global have fallen at an alarming rate – dropping by more than 62% between 1973 and 2018 – and could lead to a reproductive crisis, new research has found.
According to peer-reviewed research, the men’s sperm concentration dropped by 51% during the same time period. It fell from 101.2 million to 49 millions sperm per milliliter semen. study Published Tuesday in The journal Human Reproduction Update.
That number is still above the World Health Organization’s cutoff, namely 15 million per milliliter, below which men are deemed to have Low sperm concentration The Times of Israel reported.
According to Prof. Hagai Lvine, of the Hebrew University of Jerusalem who was responsible for the investigation, the drop is alarming. study along with Prof. Shanna Swan at New York’s Icahn School of Medicine.
“We have a serious problem on our hands that, if not mitigated, could threaten mankind’s survival,” The epidemiologist stated in A statement was made, stating that the findings were to be used as “a canary in a coal mine.”
Researchers joined the Israeli and American teams. in Spain, Brazil, and Denmark studied trends in sperm counts. in Areas that were not previously covered.
Levine noted that the news doesn’t address what is causing the declines, but other researchers have Treated falling sperm counts As well as obesity, sedentary lifestyles and smoking, there are other factors that can contribute to your health, such as being exposed to pesticides or chemicals.
The same team reported on a worrying decline in 2017 in Sperm counts All over the West, according to Euronews.
It was reported that sperm could be harvested from a woman. counts in America, Europe and Australia saw their stock plummet by more than 50Between 1973 and 2011, %
The new study — which includes seven more years of statistics — is far wider in It covers 53 countries and its meta-analysis examined 223 studies using sperm samples of more than 57,000 males.
The research also sounds alarm bells for both male fertility and for men’s health in Because of low sperm counts counts Researchers noted that this was associated with an increased risk of testicular cancer, chronic disease, and shorter lifespan.
“We should be amazed and worried by the finding,” Levine stated this to The Times of Israel.
“The trend of decline is very clear. This is a remarkable finding and I feel responsible to deliver it to the world. The decline is both very real and appears to be accelerating,” He spoke to the news outlet.
Levine cited research showing that fertility drops when sperm concentrations drop under 40 million per milliliter.
He stated that, at the current rate of decline, this number will be the global average in a decade.
“What is more, we’re looking at averages, and if men are today averaging 50 million sperm per milliliter, there are large numbers of men who today have under 40 million sperm per milliliter — in other words, fertility that is actually suboptimal,” According to the Times of Israel, he said so.
Swan, of the New York’s Icahn School of Medicine, said that plummeting sperm counts These are part of an overall decline in mens’ health.
“The troubling declines in men’s sperm concentration and total sperm counts at over 1% each year as reported in our paper are consistent with adverse trends in other men’s health outcomes,” She said.
“These include testicular cancer, hormonal disruption and genital birth defects, as well as declines in female reproductive health. This clearly cannot continue unchecked,” Swan also added.
