THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Sperm production takes place inside the seminiferous tubules, which is a convoluted cluster of tubes located inside the testes.

Detailed explanation-2: -Testes (or testicles)-these are a pair of egg-shaped glands that sit in the scrotum, on the outside of the body. They produce sperm and testosterone, which is the male sex hormone.

Detailed explanation-3: -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-4: -Spermatogenesis takes place within the seminiferous tubules of the testis. These tubules form long convoluted loops that pass into the mediastinum of the testis and join an anastomosing network of tubules called the rete testis.
