When there is no trauma, no radiation damage, no damage to the seminiferous tubules, the vas deferens, men will produce sperm throughout their lives as long as they are functional, only a decline in quantity and vigor will occur. Sperm production will continue throughout a man’s life, and will not stop as he ages, but as he ages, his fertility decreases, which does not mean that sperm will not be produced. When a man is young, the sperm are more active and of a healthy quality, which makes it more likely that a woman will be able to conceive a child and give birth to a healthier child. But with age, spermatogenesis and testicular function decline, their own physical quality and immunity will also decline, as well as a variety of diseases and a combination of reasons will lead to a significant decline in the number, activity and quality of sperm, and even some of the diseases will lead to testicular function seriously reduced, so the older you get, the lower the ability to procreate.
