The testes are the glands that produce testosterone and sperm cells. Sperm cells travel from the testes to the epididymis where they are stored and mature. From the epididymis sperm cells move into the ductus deferens which enters the body and travels to the posterior bladder. From here the ductus deferens turns into the ejaculatory duct which receives fluid from the semimal vesicles. The ejaculatory duct leads to the urethra where secretions from the prostate and bulbourethral glands are added. Finally the sperm cells and seminal fluid together these make semen are ejaculated from the penis.

Urethra chapter Thirteen I KAPIANL. _-7 Male Reproductive System I medical ORGANS OF THE MALE REPRODUCTIVE SYSTEM The testes are enclosed in the scrotal sac which is lined with a smooth muscle layer called the dartos muscle. This muscle contracts when the temperatures drop near the testes causing them to withdraw closer to the body where it is warmer. Another muscle of the region is the cremaster muscle. It also contracts when it is cold but it is made of skeletal muscle. The epididymis sits on top of the testis like a small cap and is a place where sperm cells mature. The spermatic cord consists of the cremaster muscle the ductus deferens the testicular artery and a complex meshwork of veins called the pampiniform plexus. This plexus cools arterial blood flowing to the testes maintaining the testes at about 35 degrees c which is important
