Chapter 9 Flashcards
bulbourethral glands
pair of exocrine glands near the male urethra. They secrete fluid into the urethra. Also called 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 carried 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 (“Siamese”) 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 and are also called 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
prostate gland
exocrine gland at the base of the male urinary bladder. The prostate secretes one of the fluid parts of semen into the urethra during ejaculation
scrotum
external 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-line 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.
spermatozooon (plural: spermatozoa)
sperm cell
sterilization
procedure that
stromal tissue
supportive, connective tissue of an organ, as distinguished from its parenchyma. Also called stroma.
testis (plural: testes)
male gonad (testicle) that produces spermatozoa an the hormone testosterone. Testis means one testicle, and testes are two testicles.
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. Also called ductus deferens.

carcinoma of the testes (testicular cancer)
malignant tumor of the testicles
cryptorchidism; cryptorchism
undescended testicles
hydrocele
sac of clear fluid in the scrotum
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.
carcinoma of the prostate (prostate cancer)
malignant tumor (adenocarcinoma) of the prostate gland
hypospadias
congenital abnormality in which the male urethral opening is in the undersurface of the penis, instead of at its tip.
phimosis
narrowing (stricture) of the opening of the prepuce over the glans penis.
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 STD y 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.
vasectomy
bilateral surgical removal of a part of the vas deferens.
