hernia of fluid in the testis or tubes leading from the testis

congenital opening of the male urethra on the undersurface of the penis (spadias = to draw away)

malignancy of the prostate gland

inflamation of the prostate

painless, benign cyctic mass containing sperm lying above and posterior to the testicle, but separate from it

malignant tumor in one or both testicles commonly developing from the germ cells that produce sperm - classified in two groups according to growth potential

most common type of the testicular tumor, composed of immature germ cells - highly treatable with early detection

testicular tumors arising from more mature germ cells that have a tendency to be more aggressive than seminomas; often develop earlier in life (includes choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors)
