Save the ejaculate: living sperm dies out
In one of the largest experiments on male sperm quality in human history, samples from 26, 600 healthy participants in France were tested. These subjects visited specialized reproductive health clinics because their couple partners had fertility problems. Over the entire study period, the data showed that the average number of sperm per milliliter of fluid decreased from 73. 6 million to 49. 9 million.

Net sperm count is catastrophically reduced
The number of healthy, fully fertilized sperm also decreased by 33. 4% over the same period. These results are entirely consistent with a 20-year review conducted by the British Medical Journal. His data shows that between 1938 and 1990, sperm counts in different countries fell by almost half. Researchers are seriously concerned about this fact. They believe that sperm count control should become an international issue.
Epidemiologist Joël Le Moal explained in an interview with AFP These results are very similar to those obtained in entire populations of the species Homo sapiens.

Risk factors
According to researchers, what conditions affect total sperm count? One study published in the American journal Fertility and Sterility found that even laptops connected to Wi-Fi can reduce sperm quality. During the study, sperm samples were taken from 29 men. The tubes were stored at room temperature under normal conditions or next to a laptop with a wireless connection. In the second case, it was found that sperm motility was reduced and DNA was damaged.
This affects the quality and nutrition of sperm. A 2011 study found that too much red meat, trans fat, and white bread were bad for ejaculation. On the other hand, a healthier diet containing fish, fresh fruits, legumes and vegetables improves sperm quality.
Likewise, researchers have reaffirmed the benefits of exercise. The results, obtained through experiments by researchers from Yamaguchi University in Japan, showed that men who engage in moderate physical activity produce healthier sperm compared to those who are overly inactive or active.
