Detailed explanation-1: -The testis is made up of tightly packed seminiferous tubules surrounded by a vascularized interstitium. It is enclosed in a tough fibrous capsule called the tunica albuginea (Figure 2). Within the seminiferous tubules, germ cells develop into spermatozoa in a process called spermatogenesis.
Detailed explanation-2: -The testes secrete testosterone, which is necessary for proper physical development in boys. In adulthood, testosterone maintains libido, muscle strength, and bone density. Disorders of the testes are caused by too little testosterone production.
Detailed explanation-3: -The beginning of testicular development is with the formation of the genital ridge. The origin of the genital ridge is from the intermediate mesoderm. The intermediate mesoderm forms paired structures that reside beside the dorsal mesentery, specifically in the coelomic cavity.
Detailed explanation-4: -(TES-tis) One of two egg-shaped glands inside the scrotum that produce sperm and male hormones. Also called testicle.
