In this section, learn more about the male reproductive system, including the penis, testes and the accessory glands. The seminal vesicles sit superiorly to the prostate, and drain a fructose-rich alkaline fluid into the prostatic urethra. Finely detailed and labeled illustrations show: sagittal section of the. They produce a mucus secretion which serves as lubrication, expels any urine residue from the urethra and neutralises residual acidity within the urethra. The Male Reproductive System Chart is a useful tool for learning and showing the. The bulbourethral glands, or Cowper’s glands, are located posterolaterally to the membranous urethra. The prostate’s anatomy consists of three zones, the central, transitional and peripheral zones, where different pathologies arise. These enzymes enter the prostatic urethra via the prostatic ducts. It secretes enzymes into the semen which maintain the semen’s fluid state. For men, the external reproductive organs include: Penis: This tubular, muscular organ fills with blood during arousal, thus making sexual intercourse possible. The prostate gland sits inferiorly to the bladder. Many important structures run in this bundle, including the testicular artery, pampiniform plexus of testicular veins and vas deferens. The spermatic cord is a collection of blood vessels, nerves and ducts that connect the testes to the pelvic cavity. The dartos muscle is located deep to the skin and helps adjust the surface area of the scrotum, and therefore its internal temperature. The scrotum is a fibromuscular sac located posteriorly to the penis. This is the location of sperm production, maturation and storage. The testes and epididymis are located in the scrotum, suspended by the spermatic cord. The male reproductive organs include the testes, seminal vesicles, penis and some associated glands such as the prostate gland. The penis has three main anatomical sections: the root (where the penis is fixed to the pelvic floor), the body (the length of the penis) and the glans (where the urethral opening is located). The male reproductive system can be split into seven parts: the penis, the testes and epididymis, the scrotum, the spermatic cord, the prostate gland, the bulbourethral glands and the seminal vesicles. The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction.These organs are located on the outside of the body and within the pelvis. Some tissues sit outside of the pelvis, in the scrotum, which provides a cooler environment. The male reproductive system mainly resides within the pelvis.
