Chabner Language of Medicine 11th Edition / Male Reproductive System

TermDefinition
Bulbourethral Glands Pair of exocrine glands near the male urethra. They secrete fluid into the urethra. AKA Cowper glands.
Ejaculation Ejection of sperm and fluid from the male urethra.
Ejaculatory Duct Tube through which semen enters the male urethra.
Epididymis (plural: epididymides) One of a pair of long, tightly coiled tubes above each testis. It stores and carries sperm from 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 infants resulting from fertilization of two separate ova by two separate sperm cells.
Glans Penis Sensitive tip of the penis; comparable to the clitoris in the female.
Identical Twins Two infants resulting from division of one fertilized egg into two distinct embryos. Conjoined twins are incompletely separated identical twins.
Interstitial cells of the Testes Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone. AKA Leydig Cells
Parenchymal Tissue Essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm are parenchymal.
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 fluid that contributes to semen during ejaculation.
Scrotum Extrenal sac that contains the testes.
Semen Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicle secretions), discharged from the urethra during ejaculation
Seminal Vesicles Paired sac-like 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 a person's ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are sterilization procedures.
Stromal Tissue Supportive, connective tissue of an organ, as distinguished from its parenchyma. AKA Stroma
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) carrying sperm from the epididymis toward the urethra. AKA Ductus Deferens
Impotence Inability of a male to sustain an erection or achieve ejaculation
Stroma Supportive, connective tissue of an organ, as distinguished from its parenchyma. AKA Stromal Tissue
Leydig Cells Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone. AKA Interstitial Cells of the Testes.
Carcinoma of the Testes (testicular cancer) Malignant tumor of the testicles. (Seminoma, nonseminomatous, embryonal carcinoma, teratoma, choriocarcinoma, yolk sac tumor)
Seminoma Arises from embryonic cells in the testes.
Cryptorchidism; Cryptorchism Undescended testicles. Treated by orchiopexy. Associated with high risk for sterility and increased risk of developing testicular cancer.
Hydrocele Sac of clear fluid in the scrotum. Treated by needle and syringe aspirating or hydrocelectomy. Usually caused by congential or an infection.
Testicular Torsion Twisting of the spermatic cord.
Varicocele Enlarged, dilated veins near the testicle
Benign Prostatic Hyperplasia ( BPH ) Benign growth of cells within the prostate gland. S&S Urinary obstruction, inability to empty bladder. Treated with Transurethral Resection of the Prostate (TURP).
Transurethral Resection of the Prostate ( TURP ) Surgical treatment for BPH, relieves the obstruction but overgrowth of cells may recur over several years.
Carcinoma of the Prostate ( prostate cancer ) Malignant tumor (adenocarcinoma) of the prostate gland)
Digital Rectal Examination ( DRE ) Can detect the tumor at a later stage, but early detection depends on a PSA test.
Prostate-Specific Antigen ( PSA ) A protein that is secreted by tumor cells into the bloodstream. The levels are elevated in patiens with prostate cancer even at an early stage of tumor growth.
Hypospadias Congenital abnormality in which the male urethral opening is on the undersurface of the penis, instead of at its tip
Phimosis Narrowing (stricture) of the opening of the prepuce over the glans penis.
Sexually Transmitted Infections ( STIs ) Infections transmitted by sexual or other genital contact. AKA STDs.
Chlamydial Infection Bacterial invasion of the urethra and reproductive tract.
Gonorrhea Inflammation of the genital tract mucosa, caused 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 Infection of the skin and mucous membranes in the anogenital region by the human papillomavirus
Syphilis Chronic STI 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 testicles or ovaries
Circumcision Surgical procedure to remove the prepuce of the penis
Digital Rectal Examination ( DRE ) Finger palpation through the anal canal 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 light laser ( "laser TURP" )
Transurethral Resection of the Prostate ( TURP ) Excision of benign prostatic hyperplasia using a resectoscope through the urethra.
