malignant tumor in one or both testicles commonly developing from the germ cells that produce sperm ; classified in two groups according to growth potential
seminoma
most common type of testicular tumor, composed of immature germ cells ; highly treatable with early detection

hepatitis B virus (HBV)
virus that causes inflammation of the liver ; transmitted through any body fluid, including vaginal secretions, semen, and blood

virus that causes ulcer-like lesions of the genital and anorectal skin and mucosa ; after initial infection, the virus lies dormant in the nerve cell root and may recur at times of stress
human immunodeficiency virus (HIV)
virus that causes acquired immunodeficiency syndrome (AIDS), which permits various opportunistic infections, malignancies, and neurologic diseases ; contracted through exposure to contaminated blood or body fluid
human papilloma virus (HPV)
virus transmitted by direct sexual contact that causes an infection that can occur on the skin or mucous membranes of the genitals
