sterilization
Procedure that removes an individual's ability to produce or release reproductive cells.
benign prostatic hyperplasia
Prostatic enlargement, nonmalignant
purulent
Pus-filled; forming or containing pus.
penile
Relating to the penis
orchiectomy
Removal (excision) of a testis.
prostatectomy
Removal (excision) of the prostate gland.
castration
Removal of sex glands (gonads); ovaries or testes.
photoselective vaporization of the prostate
Removal of tissue to treat benign prostatic hyperplasia (BPH) using a GreenLight laser (laser TURP).
vasectomy
Removing a piece of each vas deferens and tying off each end.
scrotum
Sac that contains the testes and associated organs.
oligospermia
Scanty (less than the normal number of sperm in semen) sperm count.
glans penis
Sensitive tip (surrounded by foreskin) of the penis.
syphilis
Sexually transmitted infection caused by bacteria (spirochetes). A chancre (ulcer) on the genitalia is a characteristic lesion.
gonorrhea
Sexually transmitted infection involving inflammation of genital tract mucous membranes and caused by gonococci (berry-shaped bacteria).
herpes genitalis
Sexually transmitted infection of the skin and mucosa of the genitals caused by the herpes simplex virus and marked by blisters.
spermatozoon
Single sperm cell.
spermatozoa
Sperm cells.
stromal tissue
Supportive, connective tissue of an organ.
orchiopexy
Surgical fixation of an undescended testis in the scrotum.
circumcision
Surgical removal of the foreskin (prepuce) surrounding the end of penis.
balanitis
Inflammation of the glans penis.
prostatitis
Inflammation of the prostate gland.
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.
perineum
Area between the anus and vagina in females and the area between the anus and scrotal sac in males.
chlamydial infection
Bacterial infection causing pelvic inflammation in the reproductive tract of women and men.
aspermia
Failure in a male sperm cells (spermatozoa) production as well as ejaculation of semen (fluid and sperm cells).
semen
Fluid discharged at ejaculation; consisting of sperm cells and secretions from the prostate gland, seminal vesicles, and bulbourethral glands.
prepuce
Fold of skin covering the glans penis (tip of the penis); foreskin.
spermatogenesis
Formation of sperm cells.
parenchymal tissue
Functional, essential tissue of an organ. The seminiferous tubules are the parenchyma of the testis.
hydrocele
Hernia (sac of clear, watery fluid) within the scrotum.
interstitial cells of the testes
In the testes, these cells lie between the seminiferous tubules and produce testosterone.
impotence
Inability of an adult male to achieve an erection; erectile dysfunction.
erectile dysfunction
Inability of an adult male to achieve an erection; impotence.
human papillomavirus infection
Infection of the skin and mucous membranes in the anogenital region by the human papillomavirus
orchitis
Inflammation of a testis.
epididymitis
Inflammation of an epididymis.
azoospermia
Lack of live spermatozoa in the semen.
penis
Male genital organ composed of erectile tissue.
testis
Male gonad that produces spermatozoa (sperm cells) and the hormone, testosterone.
androgen
Male hormone responsible for developing and maintaining male secondary sex characteristics.
testosterone
Male hormone secreted by the interstitial cells of the testes.
teratoma
Malignant tumor of a testis or ovary; composed of embryonic cells that develop into different types of tissue.
embryonal carcinoma
Malignant tumor of the testes.
seminoma
Malignant tumor within a testis.
vas deferens
Narrow tube (one on each side) that carries sperm from the epididymis into the body, around the urinary bladder toward the urethra.
seminiferous tubules
Narrow, coiled tubules that produce spermatozoa in the testes.
phimosis
Narrowing (stricture) of the opening of the prepuce (foreskin) over the glans penis.
vasovasostomy
New opening (anastomosis) of the ends of a severed vas deferens. This surgical procedure reverses a vasectomy.
bulbourethral glands
One of a pair of exocrine glands, located on either side of the male urethra, gland just below the prostate gland. It secretes fluid that is part of semen; Cowper gland.
epididymis
One of a pair of long, tightly coiled tubes lying on top of each testis. It carries sperm cells to the vas deferens.
cryptorchism
One or both testes fail to descend from the abdomen in the scrotal sac near the time of birth.
seminal vesicles
Pair of sac-like male exocrine glands lying behind the urinary (remove vesicle) bladder and opening into the vas deferens.
testicular
Pertaining to a testis or testicle.
spermolytic
Pertaining to destruction of sperm cells.
ejaculatory duct
Tube through which semen enters the male urethra.
testicular torsion
Twisting of the spermatic cord and blood vessels of the testes.
fraternal twins
Two infants born from a pregnancy resulting from fertilization of two separate ova.
identical twins
Two infants resulting from division of one fertilized egg into two separate embryos.
ligation
Tying off a tube or blood vessel. Thread or wire is used.
cryogenic surgery
Use of extremely cold temperatures to freeze or destroy tissue.
flagellum
a hair-like projection on a sperm cell that makes it motile.
