Male reproductive system

glans penis

epididymis

testis or testicle

perineum

prostate

sperm (seed)

vessel

skin-covered puch in the groin divided into two sacs, each containing a testis and an epididymis

one of the two male reproductive glands, located int eh scrotum, that produce sperm and the hormone testosterone

male gamete or sex cell produced in the testes that unites with the ovum in the female to produce offspring

coiled duct on the top and at the side of the testis that stores sperm before emission

erectile tissue covered with skin that contains the urethra for urination and the ducts for secretion of seminal fluid (semen)

bulging structure at the distal end of the penis

foreskin; loose casing that covers the glans penis; removed by circumcision

duct that carries sperm from the epididymis to the ejaculatory duct

one of two sac-like structures behind the bladder and connected to the vas deferens on each side; secretes and alkaline substance into the semen to enable the sperm to live longer

a mixture of the secretions fo the testes, seminal vesicles, prostate, and bulbourethral glands discharged from the male urethra during orgasm

duct formed by the union of the vas deferens with the duct of the seminal vesicle; its fluid is carried into the urethra

trilobular gland that encircles the urethra just below the bladder and secretes an alkaline fluid into the semen

pair of glands below the prostate, with ducts opening into the urethra, that adds a viscid (sticky) fluid to the semen

external region between the scrotum and anus in a male and between the vulva and anus in a female

inability to secrete or ejaculate sperm

semen without living spermatozoa; a sign of infertility in a male

scanty production and expulsion of sperm

drainage of mucus and pus

absence of one or both testes

inflammation of the glans penis

undescended testicle, or failure of a testis to descend into the scrotal sac during fetel development; the testis most often remains lodged in the abdomen or inguinal canal, requiring surgical repair

inflammation of the epididymis

failure to initiate or maintain an erection until ejaculation b/c of physical or psychologic dysfunction; formerly termed impotence

hernia fluid in the testis or in the tubes leading from the testis

congenital opening of the male urethra on the undersurface of the penis

disorder characterized by a buildup of hardened fibrous tissue in the corpus cavernosum, causing pain and a defective curvature of the penis, especially during erection

a narrowed condition of the prepuce (foreskin) resulting in its inability to be drawn over the glans penis, often leading to infection; commonly requires circumcision

enlargement of the prostate gland, common in older men, causing urinary obstruction

malignancy of the prostate gland

inflammation of the prostate

painless, benign cystic mass containing sperm lying above and posterior to, but separate from, the testicle

malignant tumor in one or both testicles commonly developing from the germ cells that produce sperm; classified in two groups according to growth potential

most common type of testicular tumor, composed of immature germ cells; highly treatable with early detection

testicular tumor arising from more mature germ cells; these tumors have a tendency to be more aggressive than seminomas and often develop earlier in life; includes choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors

enlarged , swollen, herniated veins near the testis

most common sexually transmitted bacterial infection in North America; often occurs with no symptoms and is treated only after it has spread

contagious inflammation of the genital muccous membranes caused by invasion of the gonococcus Neisseria gonorrhea

sexually transmitted infection caused by a spirochete and which may involve any organ or tissue over time; usally manifests first on the skin, with the appearance of small, painless, red papules that erode and form bloodless ulcers called chancres

virus that causes inflammation of the liver; transmitted through any body fluid, including vaginal secretions, seme, and blood

virus that causes acquired immunodeficiency syndrome (AIDS), which permits various opportunistic infections, malignancies, and neurologic diseases, contracted through exposure to contaminated blood or body fluid

virus transmitted by direct sexual contact that causes an infection that can occur on the skin or mucous membranes of the genitals

lesion that appears as a result of human papilloma virus; on the skin, lesions appear as cauliflower-like warts, and on mucous membranes, they have a flat appearance; also known as venereal or genital warts

tissue sampling used to identify neoplasia

needle biopsy of the prostate; often performed using ultrasound guidance

biopsy of a testicle

insertion of a finger into the male rectum to palpate the rectum and prostate

blood test used to screen for prostate cancer; an elevated level of the antigen indicates the possible presence of tumor

x-ray of the urethraand prostate

study of semen, including a sperm count with observation of morphology (form) and mobility; usually performed to rule out male infertility

scan of the prostate made after introducing an ultrasonic transducer into the rectum; also used to guide needle biopsy

removal of the foreskin (prepuce), exposing the glans penis

removal of an epididymis

removal of a testicle

repair of a testicle

fixation of an undescended testis in the scrotum

excision of the prostate gland

removal fo prostatic gland tissue through the urethra using a resectoscope, a specialized urologic endoscope; common treatment for benign prostatic hyperplasia/hypertrophy (BPH)

removal of the segment of the vas deferens to produce sterility in the male

restoration of the function of the vas deferens to regain fertility after a vasectomy

treatment of malignancies, infections, and other diseases with chemicla agents that destroy selected cells or impair their ability to reproduce

treatment of neoplastic disease using radiation, usually from a cobalt source, to stop the proliferation of malignant cells

radiation therapy technique involving internal implantation of radioactive isotopes, such as radioactive seeds to treat prostate cancer

use of a hormone to remedy a deficiency or regulat production

implantation of a device designed to provide an erection of the penis; used to treat physicla impotence

intracavernosal injection therapy causing an erection; used in treatment of erectile dysfunction

benign prostatic hyperplasia; benign prostatic hypertrophy

biopsy

digital rectal exam

erectile dysfunction

heapatitis B virus

human immunodeficiency virus

human papilloma virus

hormone replacement therapy

herpes simplex virus type-2

prostate-specific antigen

sexually transmitted disease

transurethral resection of the prostate
