Terms | Definitions |
|---|---|
 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. |

| test/o | testis, testicle |
| varic/o | varicose veins |
| cas/o | vessel, duct; vas deferens |
| zo/o | animal life |
| -genesis | formation |
| -one | hormone |
| -pexy | fixation, put in place |
| -stomy | new opening |
| carcinoma of the testes (testicular cancer) | Malignant tumor of the testicles |
| cryptorchidism; cryptorchism | 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. |
