Research shows that men’s sperm count has steadily declined over the past 40 years. But researchers aren’t sure exactly why this is happening.
The researchers believed that there could be multiple reasons behind the decrease in sperm count, from smoking, alcohol consumption, to environmental pollution. Now the problem of obesity has been added to that list.
According to a group of researchers from the University of Utah in America, the problem of obesity can significantly reduce the number of sperm. This problem increases especially after forty years. And this problem is most prevalent in people over 60 years of age. Researchers also claim that the sperm count is at its highest from the age of 17 to 40 years.
In this study, scientists have examined about 40 thousand sperm cells. Genetic material RNA from sperm cells is tested to see how well those cells are able to produce sperm.
The results of the research show that sperm production is disrupted in those whose ‘body mass index’ or ‘BMI’ is more than 30 times. Scientists fear obesity can reduce secretion of the sex hormone testosterone. As a result, sperm production may be disrupted. However, they also think that more detailed research is needed on this subject.
