THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored.

Detailed explanation-2: -The male gonads, testes or testicles, begin their development high in the abdominal cavity, near the kidneys. During the last two months before birth, or shortly after birth, they descend through the inguinal canal into the scrotum, a pouch that extends below the abdomen, posterior to the penis.

Detailed explanation-3: -During spermatogenesis, your testicles make several million sperm per day-about 1, 500 per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm.
