Terminology of the Male Reproductive System
| Term | Definition |
|---|---|
| interstitial cell | in the testes, these cells lie between the seminiferous tubules and produce testosterone |
| parenchyma | tissue composed of essential and functional cells of organ. in the testes, the parenchymal tissue includes seminiferous tubules that produce sperm |
| perineum | external region between the anus and scrotum in the male |
| prepuce | fold of skin covering the tip of the penis. also called foreskin |
| prostate gland | exocrine gland, in men, at tthe base of the urinary bladder. the prostate gland 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 (propastic and other glandular secretions) |
| seminal vesicle | either of paired sac-like male exocrine glands that secrete a fluid into the vas deferens. the seminal fluid is the major component of semen |
| seminiferous tubules | narrow, coiled tubules that produce sperm in the testes |
| spermatozoon (plural: spermatozoa) | sperm cell |
| sterilization | any procedure that removes an individuals 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 the male sex charecteristics |
| vas deferens | narrow tube (one on each side) that carries sperm from the epedidymis into the body and toward the urethra. also called ductus deferens |
| carcinoma of the testes | malignant tumor of the testicles |
| cryptorchism; cryptorchidism | undescended testicles |
| hydrocele | sac of clear fluid on the scrotum |
| testicular torsion | twisting of the spermatic cord |
| varicocele | enlarged, dilated veins near the testicle |
| bulbourrethral gland | one pair of exocrine glands near the male urethra |
| cowper gland | bulbourethral gland |
| ejaculation | ejection of sperm and fluid from the urethra |
| ejaculatory duct | tube through which semen enters the male urethra |
| epididymis | one of a pair of long, tightly coiled tubes lying 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 infants born of the same pregnancy from two seperate ova 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 |
| impotance | inability of an adult male to achieve an erection |
| carcinoma of the prostate | malignant tumor of the prostate gland |
| prostatic hyperplasia | benign growth of cells within the prostate gland; benign prostatic hyperplasia (BPH) |
| hypospadias; hypospadia | congenital abnormality in which the male urethral opening is on the undersurface of the penis instead of at its tip |
| phimosis | narrowing of the opening of the prepuce over the glans penis |
| chlamydial infection | bacteria invade the urethra and reproductive tract of men and women |
| gonorrhea | inflammation of the genital tract mucous membranes, caused by infection with gonococci |
| herpes genitalis | infection of the skin and mucosa of the genitals, caused by the herpes simplex virus and marked by blisters |
| syphilis | chronic STD caused by a spirochete (spiral-shaped bacterium) |
| PSA test | measures levels of prostate-specific antigen in the blood |
| semen analysis | ejaculated fluid is examined microscapically |
| 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 |
| vasectomy | bilateral surgical removal of a part of the vas deferens |
