Document Summary
The urinary and reproductive systems are connected in males. The primary sex organs in males are the gonads (testes). The testes form spermatozoa and secrete sex hormones (androgens). The secondary sex organs are involved in the transmission of sperm, and they include ducts, accessory glands, and copulatory organ. The ducts consist of the epididymis, ductus (vas) deferens, ejaculatory duct, and urethra. The accessory glands consist of the seminal vesicles, prostate gland, and bulbourethral gland. External genitalia scrotum: the scrotum is a fibromuscular sac of pigmented skin and superficial fascia. When it is cold, the testes/scrotum are pulled closer to the body wall and when it is warm, the scrotal skin becomes flaccid and lose. Musculature of the scrotum: the dartos muscle is smooth muscle located within the superficial fascia. It is located just beneath the skin and is responsible for wrinkling the scrotal skin. Cremaster muscle is a continuation of the internal oblique muscle.
