MICROANATOMY

Detailed explanation-1: -Penis-the organ used for urination and sexual intercourse. It has spongy tissue which can fill with blood to cause an erection. It contains the urethra, which carries both urine and semen. Scrotum-this is a loose bag of skin that hangs outside the body, behind the penis.

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: -The male reproductive system includes the testes, scrotum, spermatic ducts, male accessory glands, and penis. All these organs work together to produce sperms, the male gamete, male sex hormones and other components of semen. Penis and Urethra are a part of both the reproductive and urinary systems.
