In the study Shocking Revelations
DNA fragmentation analysis is currently the only evidence-based test for determining the functionality of sperm cells. The more fragmented the DNA, the lower the fertility potential of the sperm; In addition, it may increase the risk of miscarriage. The scientists based their research on nearly 27,000 studies, in what is believed to be the largest meta-analysis ever conducted. Effect on quality
In the current study, researchers demonstrated that smoking can increase DNA fragmentation by an average of 9.19% in smokers compared to nonsmokers. There is an effect and the sperms start becoming active. Furthermore, alcohol consumption and body weight did not have a clinically significant role in sperm quality. While some infections such as chlamydia and HPV did not impair sperm quality, bacteria or other sexually transmitted diseases showed an increase in DNA fragmentation (8.98 percent and 5.54 percent).
For these reasons Sperm count is also low
Like women, the risk of low sperm count and infertility increases with age. After the age of 30 there is a decrease in the production of testosterone levels, which is known to affect sperm production. On the other hand, in men between the ages of 40 and 70, the chances of erectile dysfunction increase by 3 times, due to which less number of sperm comes out. Long-term use of drugs like cocaine and marijuana causes sperm deficiency.
