scrotum
a bag
skin-covered pouch in the groin that is divided into two sacs, each containing a testis and an epididymis
testis (testicle)
one of the two male reproductive glands, located in the scrotum, that produces sperm and the male hormone testosterone
sperm
spermatozoon
male gamete or sex cell produced in the testes that unites with the ovum in the female to produce offspring
epididymis
coiled duct on top and at the side of the testis that stores sperm before emission
penis
erectile tissue covered with skin that contains the urethra for urination and ducts for the secretion of seminal fluid (semen)
glans penis
bulging structure at the distal end of the penis (glans = acorn)
prepuce
foreskin
loose casing covering the glans penis - removed by circumcision
vas deferens
duct that carries sperm from the epididymis to the ejaculatory duct (vas = vessel, deferent = carrying away)
seminal vesicle
one of two sac-like structures lying behind the bladder and connected to the vas deferens on each side - secretes an alkaline substance into the semen to enable the sperm to live longer
semen
mixture of the secretions of the testes, seminal vesicles, prostate, and bulbourethral glands discharged from the male urethra during orgasm
ejaculatory duct
duct formed by the union of the vas deferens with the duct of the seminal vesicle
its fluid is carried into the urethra
prostate gland
trilobular gland that encircles the urethra just below the bladder - secretes an alkaline fluid into the semen
bulbourethral glands (Cowper glands)
pair of glands below the prostate with ducts opening into the urethra - adds a viscid (sticky) fluid to the semen
perineum
external region between the scrotum and anus in a male and between the vulva and anus in a female
spermatic cord
cord containing the vas deferens, arteries, veins, lymph vessels, and nerves that extends from the internal inguinal ring through the inguinal canal to each testicle
aspermia
inability to secrete or ejaculate sperm
azoospermia
semen without living spermatozoa, a sign of infertility in the male
oligospermia
scanty production and expulsion of sperm
mucopurulent discharge
drainage of mucus and pus
anorchism
absence of one or both testes
balanitis
inflammation of glans penis
cryptorchism
undescended testicle
failure of a testis to descend into the scrotal sac during fetal development
it most often remains lodged in the abdomen or inguinal canal, requiring surgical repair
epididymitis
inflammation of the epididymis
hydrocele
hernia of fluid in the testis or tubes leading from the testis
hypospadias
congenital opening of the male urethra on the undersurface of the penis
erectile dysfunction (ED)
failure to initiate or maintain an erection until ejaculation because of physical or psychological dysfunction
formerly termed impotence
Peyronie disease
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
phimosis
narrowed condition of the prepuce (foreskin) resulting in the inability to be drawn over the glans penis, often leading to infection - commonly requires circumcision
benign prostatic hyperplasia/hypertrophy (BPH)
enlargement of the prostate gland
frequently seen in older men, causing urinary obstruction
prostate cancer
malignancy of the prostate gland
prostatitis
inflammation of the prostate
spermatocele
painless, benign cystic mass containing sperm lying above and posterior to the testicle, but separate from it
testicular cancer
malignant tumor in one or both testicles commonly developing from the germ cells that produces sperm - classified into two groups according to growth potential
seminoma
most common type of testicular tumor, composed of immature germ cells - highly treatable with early detection
nonseminomas
testicular tumors arising from more mature germ cells that have a tendency to be more aggressive than seminomas
often develop earlier in life (includes choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors)
varicocele
enlarged, swollen, herniated veins near the testis
Major bacterial STDs
chlamydia
gonorrhea
syphilis
chlamydia
most common sexually transmitted bacterial infection in North America
often occurs with no symptoms and is treated only after it has spread
gonorrhea
contagious inflammation of the genital mucous membranes caused by invasion of the gonococcus Neisseria gonorrhoeae
syphilis
infectious disease caused by a spirochete transmitted by direct intimate contact that may involve any organ or tissue over time
usually manifested first on the skin with the appearance of small, painless red papule that erode and form bloodless ulcers called chancres
Major viral STDs
hepatitis B virus (HBV)
herpes simplex virus 2 (HSV-2)
human immunodeficiency virus (HIV)
human papilloma virus (HPV)
hepatitis B virus (HBV)
virus that causes inflammation of the liver as a result of transmission through any body fluid, including vaginal secretions, semen, and blood
herpes simplex virus 2 (HSV-2)
virus that causes ulcer-like lesions of the genital and anorectal skin and mucosa
after initial infection, the virus lies dormant in the nerve cell root and may recur at times of stress
human immunodeficiency virus (HIV)
virus that causes acquired immunodeficiency syndrome (AIDS), which permits various opportunistic infections, malignancies, and neurological diseases
contracted through exposure to contaminated blood to body fluid
human papilloma virus (HPV)
condyloma acuminatum
virus transmitted by direct sexual contact that causes an infection that can occur on the skin or mucous membranes of the genitals
on the skin, the lesions appear as cauliflower-like warts, and on the mucous membranes, they have a flat appearance (also known as venereal or genital warts)
biopsy (Bx)
tissue sampling used to identify neoplasia
biopsy of the prostate
needle biopsy of the prostate often performed using ultrasound guidance
testicular biopsy
biopsy of a testicle
digital rectal exam (DRE)
insertion of a finger into the male rectum ti palpate the rectum and prostate
prostate-specific antigen (PSA)
blood test used to screen for prostate cancer
an elevated level of the antigen indicates the possible presence of tumor
urethrogram
x-ray of the urethra and prostate
semen analysis
study of semen, including a sperm count, with observation of morphology (form) and motility
usually performed to rule out male infertility
endorectal (transrectal) sonogram of the prostate
scan of the prostate made after introducing an ultrasonic transducer into the rectum - also used to guide needle biopsy
circumcision
removal of the foreskin (prepuce), exposing the glans penis
epididymectomy
removal of the epididymis
orchiectomy
orchidectomy
removal of a testicle
orchioplasty
repair of a testicle
orchiopexy
fixation of an undescended testis in the scrotum
prostatectomy
excision of the prostate gland
transurethral resection of the prostate (TURP)
removal of prostatic gland tissue though the urethra using a resectoscope, a specialized urological endoscope - common treatment for benign prostatic hyperplasia/hypertrophy (BPH)
vasectomy
removal of a segment of the vas deferens to produce sterility in the male
vasovasotomy
restoration of the function of the vas deferens to regain fertility after vasectomy
chemotherapy
treatment of malignancies, infections, and other diseases with chemical agents that destroy selected cells or impair their ability to reproduce
cancer immunotherapy
treatment of cancer by stimulating the patient’s own immune response by transfer of immune components such as antibodies or T cells from an outside source to kill cancer cells
radiation therapy
treatment of neoplastic disease by using radiation to deter the proliferation of malignant cells
brachytherapy
radiation technique involving internal implantation of radioactive isotopes, such as radioactive seeds to treat prostate cancer (brachy = localized application)
hormone replacement therapy (HRT)
use of a hormone to remedy a deficiency or regulate production (e.g., testosterone)
penile prosthesis
implantation of a device designed to provide an erection of the penis - used to treat physical impotence
penile self-injection
intracavernosal injection therapy causing an erection - used in treatment of ED
