There are a large number of curved seminiferous tubules in the testis
huge ass , which contain interstitial cells. The seminiferous tubule is the place where sperm are produced, and the number of sperm produced in a lifetime can reach more than 1 trillion. Normal men with relatively heavy testes on the right side have two testes, located on the left and right sides of the scrotum, and are ovoid and gray-white. Generally, the left side is 1 cm lower than the right side. The testicle of the famous Italian statue David clearly shows this feature. Adult testicles are 3.5-4.5 cm long, 2-3 cm wide

Newborn testes are relatively large and shrink about 1-2 months after birth. Before sexual maturity, the testes are basically in a static state and develop rapidly after entering puberty. By the age of 50, it gradually shrank and became smaller. Sperm are produced in the testicles of adults all the time. Adults can produce 300-600 sperm per second per gram of testicular tissue, and hundreds of millions of sperm can be produced on both sides of the testis every day. This is one of the reasons why male contraceptive methods to control sperm production are much more difficult than suppressing ovulation in women. The testes produce at least 1 trillion sperm during their lifetime.
