bulbourethral glands
A pair of exocrine glands near the male urethra. They secrete fluid into the urethra. Also called Cowper glands.
ejaculation
Ejection of sperm and fluid from the male urethra
ejaculatory duct
Tube through which semen enters the male urethra
epidiymis (plural: epididymides)
One of a pair of long, tightly coiled tubes on top of each testis. It carries sperm from the seminiferous tubules to the vas deferens.
erectile dysfunction
Inability of an adult male to achieve an erection; impotence.
flagellum
Hair-like projection on a sperm cell that makes it motile (able to move)
fraternal twins
Two infant boys born of the same pregnancy from two separate eggs and fertilized by two different sperm.
glans penis
Sensitive tip of the penis
identical twins
Two infants resulting from division of one fertilized egg into two distinct embryos. Conjoined (Siamese) twins are incompletely separated identical twins.
parenchyma
The essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm are the parenchymal tissues.
penis
Male external organ of reproduction
perineum
External region between the anus and scrotum in the male
prepuce
Foreskin; fold of skin covering the tip of the penis
prostate gland
Exocrine gland at the base of the male urinary bladder. The prostate secretes the fluid part of semen into the urethra during ejaculation.
scrotum
External sac that contains the testes
semen
Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicle secretions)
seminal vesicles
Paired sac-like male exocrine glands that secrete fluid (a major component of semen) into the vas deferens
seminiferous tubules
Narrow, coiled tubules that produce sperm in the testes
spermatozoon (plural: spermatozoa)
sperm cell
sterilization
Procedure that removes an individual's ability to produce or release reproductive cells
stroma
Supportive, connective tissue of an organ, as distinguished from its parenchyma
testis (plural: testes)
Male gonad (testicle) that produces spermatozoa and the hormone testosterone.
testosterone
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics
vas deferens
Narrow tube (one on each side) that carries sperm from the epididymis into the body and toward the urethra. Also called ductus deferens.

Undescended testicles
hydrocele
Sac of clear fluid in the scrotum
testicular torsion
Twisting of the spermatic cord
varicocele
Benign growth of cells within the prostate gland
carcinoma of the prostate (prostate cancer)
Malignant tumor of the prostate
hypospadias; hypospadia
Congenital abnormality in which the male urethral opening is on the undersurface of penis, instead of at it's tip
phimosis
Narrowing (stricture) of the opening of the prepuce over the glans penis
chlamydial infection
Bacterial invasion (by Chlamydia trachomatis) of the urethra and reproductive tract
gonorrhea
Inflammation of the genital tract mucosa, cause by infection with gonococci (berry-shaped bacteria)
herpes genitalis
Infection of skin and genital mucosa, caused by the herpes simplex virus (HSV)
human papillomavirus (HPV)
Infection of the skin and mucous membranes in the anogenital region by the human papillomavirus
syphilis
Chronic STD caused by a spirochete (spiral-shaped bacterium)
PSA test
Measurement of levels of prostate-specific antigen (PSA) in the blood.
semen analysis
Microscopic examination of ejaculated fluid
castration
Surgical excision of the testicles or ovaries
circumcision
Surgical procedure to remove the prepuse of the penis
digital rectal examination (DRE)
Finger palpation through the anal cavity and rectum to examine the prostate gland.
photoselective vaporization of the prostate (GreenLight PVP)
Removal of tissue to treat benign prostatic hyperplasia (BPH) using a green laser (laser TURP)
transurethral resection of the prostate (TURP)
Excision of benign prostatic hyperplasia using a resectoscope through the urethra.
vasectomy
Bilateral surgical removal of a part of the vas deferens.
