In contrast to low quality eggs in women, sperm abnormal DNA (DNA fragmentation) is not mainly the cause of age. Sperm fragmentation, believed to be due to infections, high body tempo (e.g. high fever), or lifestyle factors ( e.g. smoking or substance use), may occur to men of any age.

Male fertility decreases even more gradually than female fertility, with later consequences. How is male fertility starting to decline? Unlike female fertility, male fertility declines during adult years, but experts say that the age of a man does not substantially affect his fertility until he is 40, as sperm motility / morphology declines only by 1–2 percent a year. This is very small compared with the decline in women’s egg development last year: more than 50% of women’s embryos are predicted to be normal at 38, while only 20% are likely to be normal at 42 years of age, which is a decline of 60% of the fertility over a 4-year period.
In comparison to a woman who enters menopause while her egg is running away, men undergo a decrease in male fertility, but are not infertile due to their age. It is possible (though less likely) to father a biological child for men of any generation.
Other effects of male age
While age may not be the most important factor in the decline of male fertility, there are other significant health effects of male age. There is evidence that with paternal age, probably because of genetic semen defects, the chances of error increase.
The infant is also growing in the age of its parent in cases of birth defects, schizophrenia, and autism. In one report, descendants of men over 50 were 2.2 times more likely to have autism than descendants of men under 29. At the other, with paternal age, the risk of schizophrenia increased and with men over 45, fathers with schizophrenia were twice more likely.
Researchers have not yet fully understood the mechanism for this effect. The rise in disease levels may be caused by what scientists call ‘de novo mutations’ or by genetic engineering for the first time. Yet a 2016 report concluded that de novo mutations were likely to be part of the cause; instead, scientists proposed that people with psychiatric genetic predisposition may have a greater chance of delaying fatherhood..
Why is it important to understand male fertility decline?
Unlike mothers, people wait for children longer than ever. The average age of the newborn father has increased to 30.9 in the United States, from 27.4 in 1972. In Deutschland the fathers’ mean age was 33.1; in Britain in 2003 fathers were more than 35 (25% relative to 1993). Fathers registered 40 per cent of all births. Since age is a factor in declining male fertility, the possible effect of this delay on older couples’ ability to become pregnant and have healthy babies must be understood. Above you can know about male infertility, as it is very important to understand male infertility.
Men can preserve their fertility, too
Sperm freezing is a choice for men concerned with a decrease in male fertility as well as egg freezing may maintain female fertility. People at risk of injury, such as those in the military or those on medical treatment, such as chemotherapy, which can affect fertility. And some experts say that men who won’t be fathers until their forties or their fifties often begin freezing in their thirties. In the future, this is incredibly important.
