GENERAL HISTOLOGY

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: -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.

Detailed explanation-3: -Each testicle is covered by tough, fibrous layers of tissue called the tunica. The outer layer is called the tunica vaginalis and the inner layer is called the tunica albuginea. The testicle is divided into parts called lobules. Each lobule contains tiny U-shaped tubes called seminiferous tubules.

Detailed explanation-4: -The male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include: the testicles (pronounced: TESS-tih-kulz) the duct system, which is made up of the epididymis and the vas deferens.
