| Term | Definition |
|---|---|
| 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. |

| 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. |
