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.
