According to a recent medical report, men’s sperm has been greatly affected and decreased due to several interrelated factors, with fear that the situation may worsen in the future.
The report, prepared by researchers from Hungary’s Semmelweis University, relied on a review of almost 27,000 studies to determine the reasons why men are less fertile.
The decline in the quality of a man’s sperm and its ability to fertilize raises serious medical concerns.
Health data indicates that sperm count has halved over the past fifty years, while the rate of decline has doubled since 2000.
The report highlighted a number of causes that negatively affect a man’s sperm, such as pollution, smoking, age, and certain illnesses.
The study was published in the journal Reproductive Biology and Endocrinology, which specializes in reproductive biology and andrology.
And the head of the Andrology Center of the Urology Branch of Semiuelis University, Zulte Cuba, explains that the measurement of a man’s sperm activity is based on what is called the rupture of the DNA.
He added that the analysis measures the DNA material in the semen and also monitors the genetic parts that are not affected. The normal term fetus in the womb.
According to medical standards, if the degradation of genetic material in the sperm is less than 25%, it remains in excellent condition.
But if the cracking exceeds the 25% level, it leads to a decrease in reproductive ability, and if it exceeds the 50% threshold, artificial fertilization itself becomes low chance.
Risk factors:
Studies have shown that smoking increases DNA fragmentation and sperm fragmentation by 9.19% compared to non-smokers.
- Studies have shown that alcohol consumption and being overweight are two factors that negatively affect sperm DNA.
Pollution in turn affects sperm, as evidenced by a study conducted in a highly polluted Italian region.
- There are other organic diseases that negatively affect sperm quality, such as varicocele, which increases fragmentation by 13.62%.
Tumors increase DNA fragmentation in sperm by 11.3%, along with other organic diseases.
