OVERVIEW The reproductive system consists of organs that function in the production of offspring. Insights into urological cancer. DHT mediates the androgen effect in these organs.

Figure 22.6. Innervation is provided by parasympathetic fibers of pelvic splanchnic nerves via the prostatic plexus and sympathetic fibers of the inferior hypogastric plexus. During times of lower temperatures, the Cremaster muscle contracts and pulls the scrotum closer to the body, while the Dartos muscle gives it a wrinkled appearance; when the temperature increases, the Cremaster and Dartos muscles relax to bring down the scrotum away from the body and remove the wrinkles respectively. While some females may remain with the aging silverback out of loyalty, they leave him for other groups once he dies. Edinburgh: Elsevier Churchill Livingstone.
