At present, there is no definite theory about the limit of male reproductive age. However, many studies on the fertility problems of older adults have pointed out that men over 35 or 40 years old have a significantly increased risk of sexual dysfunction, sperm quality decline, and higher prevalence of offspring.

Therefore, it is an indisputable fact that men's reproductive risk increases with age.

The influence of age on fertility

1. Decreased sperm quality

A study conducted at the University of Soroka in Israel investigated the semen volume of normal men and compared it with men's age. The researchers found that men's semen volume peaked between 30 and 35 and peaked after 55.

In addition, sperm motility changes with age. Generally speaking, the sperm motility of males is the best before 25 years old and the lowest after 55 years old. In fact, sperm motility in men over 55 is 54% lower than that in men between the ages of 30 and 35.

Sometimes, sperm motility is also related to some reproductive system diseases, such as prostatitis, seminal vesiculitis, etc. For semen problems caused by these diseases, it is safer and more effective to seek TCM treatment, such as Natural medicine Diuretic and Anti-inflammatory Pill.

Traditional Chinese medicine stresses the unity of nature and humans. When treating these diseases, this herbal pill does not treat them from a specific part alone but adjusts the patients' whole body in an all-around way. It works on the entire reproductive system.

2. Increased genetic risk

The quality of sperm DNA decreased with age. During spermatogenesis, the incidence of gene abnormality increases. Moreover, with the growth of age, the number and structural abnormalities of sperm chromosomes increased. In a study conducted at Lawrence Livermore National Laboratory (LLNL) and the University of California, Berkeley, researchers found that genetic defects in male sperm increase with age.

Other experts have done research on new gene mutations in children. The results show that the number of gene mutations from mothers increases by 0.37 every year, and the number of gene mutations from fathers increases by 1.51 every year. The new mutation rate of fathers is higher than that of mothers.

More and more studies have pointed out that the birth defects of the offspring of elderly fathers are significantly increased. If both men and women have children at an advanced age, it will further increase the risk of increased birth defects. Take the risk of Down syndrome: among women, the risk of children with Down syndrome increases with age.

In addition, the incidence of premature birth, low birth signs, neonatal convulsions, and birth defects is also high, as well as congenital heart disease and cleft lip and palate. Children born to older fathers are also at increased risk of various diseases in childhood, such as retinoblastoma, childhood leukemia, achondroplasia, and so on.

So if you want to have a baby, try to plan early. In order to improve fertility, men should strive to enhance sperm quality at ordinary times. It's best to change your living habits and diet, and try to go to bed early, get up early and eat regularly. Usually, try to participate in some sports is beneficial, like jogging, swimming, etc. Only if men improve their physical quality, then the quality of sperm in the body will be enhanced so as to prolong the time of male fertility.

In addition to age, environmental problems can also affect men's semen quality. In life, men should consciously avoid toxic substances, such as formaldehyde, food additives, pesticides, etc. In addition, automobile exhaust, electromagnetic waves, all kinds of radiation can also lead to male fertility decline.
