The male sex cell or gamete is sperm. Sperm are microscopic tadpole - like cells that are formed in the two testes. Most of each testis is made up of tiny, tightly coiled tubes called seminiferous tubules. Millions of sperm are formed in these tubes each day after puberty and will continue to be produced throughout a man's adult life. Lining the walls of the tubules are hairlike cilia that beat back and forth moving the sperm along to another group of coiled tubes located at the top pf each testis. It is here, in the epididymis, that the sperm mature and are stored, taking several weeks to do so. On orgasm, the sperm travel from the epididymis to the penis via the sperm duct and urethra. Along the way they pass the prostate gland, seminal vesicle and Cowper's glandwhich all add more fluid and sperm is called Semen. Although both men and urine pass along the urethra, it is not possible for both to pass through at the same time.
Male Secondary Sexual Characteristics
Testes produce the male sex hormone Testosterone which gives the male at puberty
More Muscular Deepening of the voice Growth of hair on the face and body Could go bald
Functions of the Reproduction System
Penis: Sponge like tissue that fills with blood when is sexually aroused. The tissue gets larger and becomes harder causing an erection
Epididymis: long coiled tubes at the top of the testis where sperm is kept and stored
Testicles/Testis: Tiny tubes coiled tightly tubes called seminiferous tubules in which sperm form and grow.
Sperm Duct: Connects testes to the Penis
Bladder: Stores Urine
Ureters: Deliver urine from the kidneys to the bladder
Cowpers Gland (Prostate Gland): adds fluids to the sperm to make semen
Urethra: long tube that empties bladder of urine and allows the flow of semen.
