PATHOLOGY

Detailed explanation-1: -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. Epididymis-this is a highly coiled tube that lies at the back of the testes.

Detailed explanation-2: -One testicle is usually sufficient to produce semen and testosterone (A), although decreased semen production and quality are often seen with this condition. A testicular biopsy is not necessary as long as the semen analysis demonstrates viable sperm (C), which could be used in an in vitro fertilization procedure.
