TermDefinition
androgen Male hormone responsible for developing and maintaining male secondary sex characteristics.
aspermia Failure in male sperm cells (spermatozoa) production as well as ejaculation of semen (fluid and sperm cells).
azoospermia Lack of live spermatozoa in the semen.
balanitis Inflammation of the glans penis.
benign prostatic hyperplasia Prostatic enlargement, nonmalignant.
bulbourethral glands 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; AKA Cowper gland.
carcinoma of the prostate Malignant tumor (adenocarcinoma) of the prostate gland.
carcinoma of the testes Malignant tumor of the testicles.
castration Removal of sex glands (gonads); ovaries or testicles.
chancre Primary lesion of syphilis; a hard ulcer occurring at the site of entry of the bacterial infection and most frequently on the external genitalia of a male or female.
chlamydial infection Bacterial infection causing pelvic inflammation in the reproductive tract of women and men.
circumcision Surgical removal of the foreskin (prepuce) surrounding the end of the penis.
cryogenic surgery Use of extremely cold temperatures to freeze or destroy tissue.
cryptorchidism One or both testes fail to descend from the abdomen in the scrotal sac near the time of birth.
digital rectal exam Finger palpation through the anal canal and rectum to examine the prostate gland.
ejaculation Ejection of sperm and fluid from the male urethra as a result of sexual stimulation.
ejaculatory duct Tube through which semen enters the male urethra.
embryonal carcinoma Malignant tumor to the testes.
epididymis One of a pair of long, tightly coilled tubes lying on top of each testis. It carries sperm cells to the vas deferens.
epididymitis Inflammation of the epididymis.
erectile dysfunction Inability of an adult male to achieve an erection; impotence.
flagellu A flagellum is a hair-like projection of a sperm cell that makes it motile.
fraternal twins Two infants born from a pregnancy resulting from fertilization of two separate ova.
glans penis Sensitive tip (surrounded by foreskin) of the penis.
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.
human papillomavirus Infection of the skin and mucous membranes in the anogenital region; genital warts
hydrocele Hernia (sac of clear, watery fluid) within the scrotum.
hypospadias Congenital anomaly in which the opening of the urethra is on the underside of the penis.
identical twins Two infants resulting from division of one fertilized egg into two separate embryos.
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) perm count.
orchiectomy Removal (excision) of a testis.
parenchymal tissue Functional, essential tissue of an organ.
penile Pertaining or relating to the penis.
penis Male genital organ composed of erectile tissue.
penoscrotal Pertaining to the penis and scrotum.
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 Removal of tissue to treat benign prostatic hyperplasia (BPH) using a Green Light laser (laser TURP).
prepuce Fold of skin covering the glans penis (tip of the penis); foreskin.
prostatectomy Removal (excision) of the prostate gland.
prostate galnd 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.
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.
semen anlalysis Microscopic examination of ejaculated fluid.
seminal vesicles Pair of sac-like male exocrine glands lying behind the urinary 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 Single sperm cell.
spermolytic Pertaining to destruction of sperm cells.
sterilization Procedure that removes an individual's ability to produce or release reproductive cells.
stromal tissue Supportive, connective tissue of an organ.
syphilis Secually transmitted infection caused by bacteria (spirochetes). A chancre (ulcer) on the genitalia is a characteristic lesion.
teratoma Malignant or benign tumor of a testis or ovary; composed of embryonic cells that develop into 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 (sperm cells) and the hormone, testosterone.
testosterone Male hormone secreted by the interstitial cells of the testes.
transurethral resection of the prostate (TURP) Excision of benign prostatic hyperplasia using a resectoscope through the urethra.
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 Anastamosis of the ends of a severed vas deferens. This surgical procedure reverses a vasectomy.
