According to the sources, however, we all know that women reach menopause, after menopause, they will no longer ovulate, so will lose the ability to give birth. So, male fertility has no age restrictions?
   Number of years for male fertility problems, in Munich, Germany Makesipu Planck Research Center, made a very interesting experiment. Experts selected 20 60-89 year-old male, there are 20 24-33 year-old male, in their comparison showed that older men's sperm is not aging, then they further analysis of the two groups of male semen, The results showed that the male ancestors of the average sperm density of 120 million per milliliter, fathers, so far only 078 million.
     Hamburg study conducted by Xie Lin has the same result. He also found that older sperm in the sperm density although high, but motility has been significant drop in immobile sperm and abnormal sperm count had increased by 20%. In addition, the sperm metabolism of a number of concentrations required for the decrease in metabolism also produced after a lot of waste.
   How to determine from the clinical level of male sexual function in aging. Experts believe that mainly depends on the state of reproductive organs, the frequency of conjugal life and whether they have systemic disease. For example there is no high blood pressure, diabetes, heart disease, etc., if necessary, can be further blood test male hormone concentration as a reminder. From the clinical observation results, 31-year-old should be the peak of male puberty.
   Munich, a psychiatrist of 250 60-70 year-old male who has done a survey, they found the elderly couple living conditions and marriage have a close relationship, in which 149 elderly people have a partner, 54% still maintain 1-3 times per week about married life, to the 75-year-old was gradually reduced.
   Male fertility have shelf life. It is thus found that in young men during the sexual life if good, in old age can continue to maintain the married life. Thus, male fertility is no age limit, only the older men after the semen quality will become poorer, while the poor of the sperm and eggs are prone to the formation of the early embryo abortion, will also affect the next generation of quality.
