We are used to talking about the female biological clock, when we approach the topic of fertility. Still, the paternal age could be just as important according to a study led by Dr. Gloria Bachman.
The doctor's team examined data from over 40 years of research on male fertility. From what has emerged, men should consider having children or freezing their sperm within the age of 35. As they age they can still have children, but there is a decline in fertility and increases the risk of transmitting genetic defects. In fact, testosterone decreases with age and this affects the quantity and quality of spermatozoa.
The average age of aspiring parents is increasing: in recent years, there has been 10% more men who have had children after age 40. Although undervalued, this is a problem that affects the health of newborns in so many ways. According to some studies, it could even increase the risk of tumors, psychiatric illnesses and cognitive disorders.
The authors of the study recommend men over 35 to treat fertility like women of the same age. If they plan to have children far ahead in life, it would be better if they kept their sperm a few years in advance. Otherwise, make sure to perform prenatal tests to check the health of the fetus.
