chapter 9 Flashcards
male reproductive system
anatomy of the male reproductive system:
-testis, scrotum, perineum & seminiferous tubules
-epididymis, seminal vesicles (vas deferens), ejaculatory duct & urethra
-prostate gland & bulbourethral gland
-penis, glans penis & prepuce (foreskin)
passage of sperm from seminiferous tubules to outside of body:
seminiferous tubules, epididymis, vas deferens, ejaculatory duct, urethra & penis
bulbourethral glands (cowper glands)
part of exocrine glands near urethra
ejaculation
ejection of sperm and fluid from urethra
ejaculatory ducts
rube through which semen enter the urethra
how many sperm (spermatozoon) are released during ejaculation?
300 million
epididymis (plural: epididymides)
one of a pair of long tightly coiled tubes above each testis that stores and carries sperm to the vas deferens
erectile dysfunction (impotence)
inability of an adult male to achieve an erection
flagellum
hair-like projection on a sperm that makes it mobile
fraternal twins
two infants resulting from fertilization of two separate ova by two separate sperm cells
glans penis
sensitive tip of penis
identical twins
two infants resulting from the division of one fertilized egg into two distinct embryos
interstitial cells of the testes(leydig cells)
specialized cells adjacent to the seminiferous tubules in testes that produce testosterone
parenchymal tissue
essential distinctive cells of an organ
penis
male external organ of reproduction
perineum
external region between anus and scrotum
prepuce
foreskin, fold of skin covering the tip of the penis
prostate gland
an exocrine gland at the base of the male urinary bladder that secretes fluid part of semen into urethra during ejaculation
scrotum
external sac that contains the testes
semen
spermatozoa and seminal fluid discharges from urethra during ejaculation
seminal vesicles
paired sac-like exocrine glands that secrete fluid into the epididymis
seminiferous tubules
narrow, coiled tubules that produce sperm in testes
spermatozoon (plural: spermatozoa)
sperm cell
sterilization
procedure that removes a persons ability to produce/release reproductive cell through removal of testicles, vasectomy or oophorectomy
stromal tissue (stroma)
supportive connective tissue or organ
testis (plural:testes)
male gonad (testicle) that produces spermatozoa and testosterone
testosterone
hormone secreted by interstitial tissue if the testes, responsible for male sex characteristics
vas deferens (ductus deferens)
narrow tube carrying sperm from epididymis toward urtethra

hormone
-pexy
fixation, put in place
-stomy
new opening
hydrocele
sac of fluid in the scrotum
testicular torison
twisted spermatic cord
varicocele
dilated spermatic veins
hypospadias
surgical repair involves exciding a portion of the prepuce, wrapping it around a catheter, suturing it to the distal part of urethra, bringing it to end of the penis
sexually transmitted infections:
-chlamydial infection
-gonorrhea
-herpes genitalis
-human papilloma virus (HPV)
-syphilis
BPH
benign prostatic hyperplasia
DRE
digital rectal examiniation
ED
erectile dysfunction
GU
genitourinary
HPV
human papilloma virus
HSV
herpes simplex virus
PID
pelvic inflammatory diease
PIN
prostatic intraepithelial neoplasia
PAS
prostatic-specific antigen
RPR
rapid plasma reagin
STI
sexually transmitted infections (diseases)
TRUS
transrectal ultrasound
TUIP
transurethral incision of prostate
TUMT
transurethral microwave thermotherapy
TUNA
transurethral needle ablation
TURP
transurethral resection of the prostate
aspermia
no sperm or semen produced(lack of sperm)
oligiospermia
semen with a low concentration of sperm
semen analysis
test of fertility (reproductive ability)
purulent
pus-filled
circumision
removal of the prepuce
ligation
to tie off or bind
cryosurgery
destruction of tissue by freezing
seminonma
malignant tumor of testis
phimosis
narrowing (stricture) of the opening of the prepuce over the glans penis
benign prostatic hyperplasia
prostatic enlargement, nonmalignant
herpes genitalia
infection of skin and genital mucous with HSV
adenocarcinoma of prostate
malignant tumor of the prostate gland
syphilis
sexually transmitted disease with primary stage marked by formation of chancre
HPV infection
infection of the skin and mucous membranes in the anogenital region by human papillomavirus
gonarrhea
STI is caused by berry-shaped bacteria and marked by inflammation of genital mucosa and mucopurulent discharge
cryptorchidism
undescended testicles
PSA meaning
high serum levels of antigen protein indicate prostatic carcinoma
BPH meaning
noncancerous enlargement of prostate gland
DRE meaning
manual diagnostic procedure to examine the prostate gland
TRUS meaning
helpful procedure in guiding a prostatic biopsy needle
HSV meaning
etiologic agent of sexually transmitted disease characterized by blister formation
RALP(robotic-assisted laparoscopic prostatectomy)
assisted laparoscopic surgery to remove the prostate gland
what is the reason to perform a radical(complete) prostatectomy?
prostate cancer
what is the reason to perform a photoselective vaporization of the prostate?
benign prostatic hyperplasia
what is the reason to perform a vasovasostomy?
reversal of sterilization procedure
