A male who has reached puberty will produce millions of sperm cells every day. Each sperm is extremely small: only 1/600 of an inch (0.05 millimeters long). Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells.
What is the process of sperm development?
Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells. The sperm move into the epididymis, where they complete their development. what produces immature sperm?
Where are sperm cells produced in the testes?
Sperm cells are continually being produced by the testes, but not all areas of the seminiferous tubules produce sperm cells at the same time. The immature cells (called spermatogonia) are all derived from cells called stem cells in the outer wall of the seminiferous tubules.
