what do testes produce? They produce sperm cells and male sex hormones testosterone
How much sperm can the testes produce? The testes can produce as many as 12 trillion sperm in a male's lifetime, and about 400 million in a single ejaculation
where are testes located? They are located in a hollow sac of the scrotum
How long in diameter is each testes? About 1.5 to 2 inches long along its axis and around 1 inch in diameter
How are testes connected to the ventral body cavity? Testes are connected to the vital organs of the ventral body cavity through the spermatic cords
what does the spermatic cord transport? Nerves, blood vessels, and lymphatic vessels travel through the spermatic cords to support the testes
what wraps around the testes? The testes are wrapped by the tunica vaginalis, an extension of the peritoneum of the abdomen, and the tunica albuginea, a tough, protective sheath of dense irregular connective tissue.
The testes are divided into segments called? Lobules. Each of the Lobules contains several tightly coiled tubes called seminiferous tubules
what divides testes into segments? Testes are divided into segments by invaginations of the tunica albuginea
what does the walls of the seminiferous tubules contain? They contain the germ cells, Sertoli cells, and Leydig cells that give the testes their function
The germ cell in the walls of the seminiferous tubules differentiate to produce? Spermatocytes
what do Spermatocytes develop into? Spermatides and eventually into spermatozoa or sperm cells
what is the function of sertoli cells? They support and protect the immature cells as they travel through the seminiferous tubules and slowly mature
what is the function of the Leydig cells? They produce the male hormone testosterone that produces the secondary sex characteristics associated with males.
How long does it take each sperm to mature? It takes each sperm cell 72 days to mature
what is the function of the scrotum? It helps keep the testes and sperm at the correct temperature
why does the scrotum lie outside the body? Spermatogenesis requires a temperature that is three to five degrees Fahrenheit below body temperature. This makes it being outside the body an optimal place to be
