The male genital organ refers to the reproductive organ that is specific to males, responsible for sexual reproduction and the production of sperm cells. It is a complex organ system composed of both internal and external structures.
Externally, the male genital organ includes the penis, which is a cylindrical and erectile organ. The penis consists of three main parts: the root, body, and glans. The base of the penis anchors it to the pelvic region, while the body comprises spongy tissues that fill with blood during sexual arousal, resulting in an erection. The glans, also known as the head of the penis, is a sensitive region with numerous nerve endings.
Internally, the male genital organ encompasses the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and the urethra. The testes are the oval-shaped organs responsible for the production of sperm cells and testosterone, the primary male sex hormone. The epididymis is a coiled tube located on top of the testis, where sperm mature and are stored. The vas deferens is a muscular tube that transports mature sperm from the epididymis to the urethra. The seminal vesicles and prostate gland produce and secret fluids that mix with sperm to form semen. Finally, the urethra is a duct that carries semen and urine out of the body.
In summary, the male genital organ is an anatomical and physiological structure unique to males, encompassing both external and internal components essential for sexual reproduction and the production and transport of sperm cells.
