HEALTH - Is there a maximum age a man can be a father? In theory no, but became a father at the ripe old age affect the quality of infant health.
Because men do not go through menopause, they can still fertilize his wife until age are classified as "grandfathers". Singer Mick Jagger also became a father for the eighth child at the age of 73 years.
According to the US study, the average man becomes a father for the first child is 25 years of age, but starting in 1980 to 2014, an increasing number of men over 35 years of incipient father. The numbers increase to 58 percent.
In general, increasing age does not have a big impact on health, but that does not mean delaying the age of having children is not risk free.
"After age 30, most of the functions of reproductive organs that produce sperm began to decline. The reason is because of exposure to radiation, toxins, and also aging," said Ranjith Ramasamy, director of male reproductive medicine and surgery from the University of Mimami Miller School of Medicine.
The older men as well as exposure to toxins of the environment, then the number of Leydig cells (cells in the testes that produce testosterone) and Sertoli cells that are important for the health of new sperm cells, will decrease.
As a result, the body begins to produce sperm defects, containing the DNA mutations that are harmful to the health of the baby.
The average 30 year old man forward about 55 mutations in sperm cells. However, every 16 years the number of mutations will be doubled. At the age of 80 years, DNA mutations that passed through sperm 8 times more than at age 30 years.
The DNA mutations can cause a number of health problems, which most often is difficult to impregnate or become a greater risk of miscarriage.
Moreover, the risk of birth defects has also increased. Autism rates also rose from 1 in 1000 to 1 in 174 babies a baby whose father is 40 years old.
These risk factors can not be ignored, but the majority of older men still have a healthy baby. In fact, the age of the mother actually play a bigger role in the health of the baby. That is why women who are pregnant at the age of 35 years should monitor the pregnancy more closely.
