The Center for Medicare Advocacy produced this packet to help you understand Medicare coverage and how to file an appeal if appropriate. Medicare is the national health insurance program to which many people with disabilities and older people are entitled under the Social Security Act.
Sperm release pathway. Overview. The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testes are composed of coiled structures called seminiferous tubules, which are the sites of sperm production.
Sperm are stored within the epididymus and remain there until they mature. Once mature, sperm travel through another long tube called the vas deferens. The vas deferens carries sperm into the urethra, where the sperm exits the body. The urethra is also a part of the urinary system. It is the same tube through which urine exits the body.
