Sperm is the key to continue the next generation, so how does sperm develop during a man’s life? What happens to sperm as a man grows? Adolescence: Before development, a teenager may have a very small amount of immature sperm. After the “developmental engine” starts, there is a gradual enlargement of the scrotum and testicles, and the development of pubic hair and sperm storage sacs. By the age of 14D16, mature sperm will appear and seminal emission will occur. Age 20D29: This is the most active period in a man’s life. Each “tadpole” is ready to fertilize an egg. This is also a critical time to protect the health of the sperm. If men are active at this time, they can significantly prolong the period of active sperm and reduce the chance of erectile dysfunction in the future. Age 30D39: Men’s androgen levels begin to decline, sperm counts go down and erections become worse. 35-year-old men are twice as likely to become infertile as they were at age 25. At the same time, the chances of sperm DNA damage are also rising at this time. Men in this age group need to eat less soy products and more foods high in zinc. Age 40D49: Each year, your sperm motility decreases by 0.7%, and the number of sperm that can “swim” and “sprint” decreases by 3.1% per year. A study has proven that in order to improve the sperm status, men can take a moderate amount of vitamin B12 at this time. 50D59 years old: A study at New York University proved that if a man is over 50 years old when his wife gets pregnant, the chances of the child suffering from birth defects will be 2.1 percent. Especially those men who are taking antidepressants are more likely to have problems. They should be advised to eat more foods rich in folic acid. Over 60: After the age of 60, 85% of sperm will be malformed. Although there are some clinical cases of fathers after the age of 60, it is divided into two extremes: one is a baby with a particularly high physical and intellectual capacity, because the sperm that can successfully impregnate a woman must have a “superhuman physique”; on the other hand, the baby is suffering from a variety of diseases DDD which is more common in the clinic.
