orchiectomy
removal (excision) of a testis
orchiopexy
surgical fixation of an undescended testis in the scrotum
orchitis
inflammation of a testis
parenchyma
functional, essential tissue of a organ; the seminiferous tubules are the parenchyma of the testis

prepuce
fold of skin covering the glans penis (tip of the penis); foreskin
prostatectomy
removal (excision) of the prostate gland
prostate gland

prostatitis
inflammation of the prostate gland
purulent
pus-filled; forming or containing pus
scrotum
sac that contains the testes and associated organs
semen
fluid discharge at ejaculation; consisting of sperm cells and secretions from the prostate gland, seminal vesicles, and bulbourethral glands
seminal vesicle

twisting of the spermatic cord and blood vessels of the testes
testis
male gonad that produces spermatozoa (sperm cells) and the hormone testosterone
testosterone
male hormone secreted by the interstitial cells of the testes
varicocele
enlarged, dilated veins near a testicle
vas deferens
narrow tube (one on each side) that carries sperm from the epididymis into the body, around the urinary bladder toward the urethra
vasectomy
removing a piece of each vas deferens and tying off each end
vasovasostomy
new opening (anastgomosis) of the ends of a severed vas deferens; this surgical procedure reverses a vasectomy
