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.
The epididymis, vas deferens and seminal vesicles (male duct which transport sperm to the penis) have formed at this stage. They do not form part of the structure of the testes, but they descend with the testes into the scrotum. These ducts collectively form the spermatic cord which transports sperm to the penis.
