We all know that after menopause, women no longer ovulate, so they lose their ability to conceive. So, is there an age limit for male fertility?
The Max Planck Research Center in Munich, Germany, conducted a very interesting experiment on the issue of male reproductive age.
Experts selected 20 males aged 60-89 and 20 males aged 24-33 for comparison. The results showed that the sperm of elderly males did not age. They further analyzed the semen of two groups of males and found that the average sperm density of ancestral males was 120 million per milliliter, while that of parental males was only 78 million.
The research conducted by Professor Xie Lin from Hamburg also yielded the same results. He also found that although the density of sperm in the semen of the elderly is high, their motility has significantly decreased, and the number of immobile and deformed sperm has increased by 20%. In addition, some of the concentrations required for sperm metabolism have also been reduced, and a lot of waste has also been generated after metabolism.
How to determine the degree of aging in male sexual function from a clinical perspective?
Experts believe that the main factors to consider are the condition of the reproductive organs, the frequency of marital life, and the presence of 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. From clinical observations, the age of 31 should be the peak period of male adolescent development.
Psychiatrists in Munich conducted a questionnaire survey on 250 men aged 60 to 70 and found that there is a close relationship between the marital status and marriage of the elderly. Among 149 elderly people with partners, 54% still maintain marital life about 1-3 times a week, which 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. So, there is no age limit to male fertility. However, as men age, the quality of their semen becomes 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.
