According to a recent meta-analysis of studies done on male sperm count in Western countries, scientists from the Hebrew University Hadassah Braun School of Public Medicine in Jerusalem have found that the male population in the Western world is experiencing a decline in sperm count and concentration, which is concerning.
After investigating more than 7000 studies conducted between 1973 and 2011, the scientists identified 52.4% decline in sperm concentration and 59.3% total sperm count decline in men from Europe, Australia, New Zealand and North America. The decline was not seen in men from Africa, Asia and South America, but the truth is that few studies have been conducted in these regions. The stope of decline was steep even when the analysis was restricted to studies with samples between 1996 and 2011.
The research was led Dr. Shanna H. Swan, professor at the Icahn School of Medicine in New York and Dr. Hagai Levine from the Jerusalem-based University. They were joined by scientists from Denmark, Brazil, Spain, the USA and Israel. While the sperm count decline has been reported since 1992, the question was controversial due to the lack of solid evidence from previous studies. The current meta-analysis used a wide scope and rigorous testing methods, including factors such as age, abstinence, selection of subjects and other factors.
“Due to the importance of sperm count for male reproductive health, the research is essentially a wake-up call for health organizations and doctors around the world. The decline must be studied in depth and act on prevention, or it’ll have dire consequences on the global fertility,” Dr. Levine said.
The findings are important from many perspectives. The data shows that the sperm count in men from Western countries is rapidly decreasing, and the decline can be related to increased morbidity and mortality. This can have unforeseen consequences on male fertility and health. “For the last 25 years, the decline in total sperm count has been on the rise,” Dr. Swan says. She also says that the probable culprit is our poor diet and the exposure to toxins as well.
Although the study didn’t observe the causes of the decline, the decline in sperm count has been previously associated with environmental and lifestyle factors such as chemical and pesticide exposure, stress, obesity and smoking. Experts are urging health organizations all over the world to start providing more information on prevention of the phenomenon, or it will have dire consequences on the male health.
