Patient's question:
Sperm is produced by men every day. You can go to the hospital for a routine semen analysis, and you will know quickly. Before pregnancy, if you want to know if the sperm is healthy, if you mean the quantity, it is also not beneficial.Doctor's answer:
The cells of the human body divide, and each time the mitochondria in the cell nucleus become shorter. Until the mitochondria become too short to divide anymore. This means our cells can only divide 40 to 60 times. This also determines our lifespan, even if we never get sick, we can only live to be over 100 years old. Some animals' cells can only divide about 5 times. So they can only live for about a year. The cells in the testicles that secrete sperm also have a lifespan.
