Erectile dysfunction (impotence)

Testicles & Penis

testicleThe testicles are located in the scrotum, and are responsible for producing sperm, and testosterone, the male sex hormone. They are egg shaped, and have a firm, spongy feel. At the top of each testicle lies the epididymis, which transports sperm from the testicle to the vas deferens (also called spermatic cord), a long tube which then takes the sperm into the urethra.

The testicles are approximately the same size and shape, and should have the same consistency throughout.
A number of different conditions can affect the testicles. These include various causes of testicular swelling, of which testicular cancer, hydrocoele, and epididymal cysts are some.
