impotence

inability of an adult male to achieve an erection; erectile dysfunction

interstitial cells of the testes

in the testes, these cells lie between the seminiferous tubules and produce testosterone

ligation

tying off a tube or blood vessel. thread or wire is used

oligospermia

scanty (less than the normal number of sperm in semen) sperm count

orchiectomy

removal (excision) of a testis

orchiopexy

surgical fixation of an undescended testis in the scrotum

orchitis

inflammation of a testis

parenchymal tissue

functional, essential tissue of an organ. the seminiferous tubules are the ___ of the testis.

penile

relating to the penis

penis

male genital organ composed of erectile tissue

perineum

area between the anus and vagina in females and the area between the anus and scrotal sac in males

phimosis

narrowing (stricture) of the opening of the prepuce (foreskin) over the glans penis

photoselective vaporization of the prostate

prepuce

fold of skin covering the glans penis (tip of the penis); foreskin

prostate gland

a gland in men that surrounds the neck of the urinary bladder and urethra. it produces a fluid which, after combining with sperm cells, leaves the body as semen.

prostatectomy

removal (excision) of the 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 discharged at ejaculation; consisting of sperm cells and secretions from the prostate gland, seminal vesicles, and bulbourethral glands

seminal vesicles

pair of sac-like male exocrine glands lying behind the urinary (remove vesicle) bladder and opening into the vas deferens

seminiferous tubules

narrow, coiled tubules that produce spermatozoa in the testes

seminoma

malignant tumor within a testis

spermatogenesis

formation of sperm cells

spermatozoa

sperm cells

spermatozoon

spermolytic

pertaining to destruction fo sperm cells

sterilization

procedure that removes an individual’s ability to produce or release reproductive cells

supportive, connective tissue of an organ

syphilis

sexually transmitted infection caused by bacteria (spirochetes). a chancre (ulcer) on the genitalia is a characteristic lesion

teratoma

malignant tumor of a testis or ovary; composed of embryonic cells that develop in to different types of tissue

testicular

pertaining to a testis or testicle

testicular torsion

twisting of the spermatic cord and blood vessels of the testes

testis

male gonad that produces spermatozoa and the hormone testosterone

testosterone

male hormone secreted by the interstitial cells of the testes

varciocele

enlarged, dilated veins near a testicle

vas deferens

narrow tube 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

vasovasotomy

new opening at of the ends of a severed vas deferens. this surgical procedure reverses a vasectomy
