All men know that over the years, even in a very subtle way, there is a decreased amount of sperm, especially noticeable between 45 and 50 years. But some usual attitudes of everyday life can also affect the production and quality of sperm.
According to research by Dr. Edson Borges Jr., an expert on assisted human reproduction and scientific director of the Fertility Medical Group, the changes in the lifestyle of men, that have occurred in recent years, reduce the quality and quantity of sperm they produce, in order to reduce the fertility rate.
To achieve this result, two surveys were conducted, one in 2000 and 2002 and another between 2010 and 2012. In total, 2300 people participated, 764 on the first date and the second in 1536.
The age range of participants was the same in both groups, but the result was quite different: In the first period, the number of sperm in each ejaculation was 61 million. In the second, it was only 27 million.
Another aspect of the research that scared the doctors involved in the study was that, ten years ago, the number of men with oligozoospermia (decreased number of sperm) was 16% of the participants. Ten years later it increased to 30%. Those with azoospermia (no sperm) increased from 5% to 8.5%. And the factors responsible for these figures were time and current lifestyle.
But what men can do to change that?
Dr. Borges suggests:
- Find a dietitian;
- Improving nutrition;
- Doing physical exercises;
- control weight;
- Avoid or reduce stress;
- not use drugs, such as cigarettes and alcohol.
Other factors, unfortunately, seem to have no solution: environmental pollution, water contamination, irradiation. Situations, then, that have already been proven and alter other agencies also undertake testicular function in sperm production
