The Max Planck Research Center in Munich, Germany, conducted a very interesting experiment on the issue of male reproductive age.
Experts selected 20 men aged 60 to 89, and 20 men aged 24 to 33, and compared them. The results showed that the spermatozoa of elderly men did not age. Then they further analyzed the semen of the two groups of men, and found that the average sperm density of ancestral men was 120 million per milliliter, while that of their fathers was only 78 million.
A study by Professor Xie Lin of Hamburg has the same results. He also found that although the density of spermatozoa in the semen of the elderly is high, their activity has significantly decreased, with the number of immobile and deformed spermatozoa increasing by 20%. In addition, some of the concentrations required for sperm metabolism have also decreased, and many wastes have also been generated after metabolism.
How to determine the aging degree of male sexual function clinically
Experts believe that the main thing to look at is the state of the reproductive organs, the frequency of marital life, and whether there are systemic diseases. For example, whether there is hypertension, diabetes, heart disease, etc. When necessary, you can also draw blood to test the concentration of male hormones as evidence. According to clinical observations, the age of 31 should be the peak of male puberty.
Psychiatrists in Munich have conducted a questionnaire survey on 250 men aged 60 to 70 years. They found that there is a close relationship between the marital life status of the elderly and their marriage. Among the 149 elderly who have partners, 54% still maintain marital life about 1-3 times a week, and it gradually decreases by the age of 75.
It is not difficult to find that if men have a good sexual life in their youth, they can continue to maintain their marital life in old age. Therefore, there is no age limit to male fertility. However, as men age, the quality of semen will become poorer, and embryos formed by poor sperm and eggs are more likely to cause early miscarriage, which can also affect the quality of the next generation.
Comprehensive treatment of "ejaculation" is important: to correctly understand and treat the issue of frequent ejaculation. Don't carry a mental burden on this, or worry too much about frequent ejaculation, focus too much on this issue, and worry too much. Unnecessary mental burdens can have a negative impact on the body, but can lead to an increase in the number of ejaculation, falling into a "vicious circle" and not being able to extricate yourself.
