CHAPTER 7: MALE REPRODUCTIVE SYSTEM

Question 1

Male reproductive organs

Answer 1

externally: penis and scrotum
internally: major portion of vas deferens, seminal vesicles, prostate gland

Question 2

sperm (spermatozoon)

Answer 2

microscopic male germ cell which when united with ovum, produces a zygote (fertilized egg) that develops into an embryo

Question 3

seminiferous tubules

Answer 3

up to 900 coiled tubes within the testes in which spermatogenesis occurs

Question 4

epididymis

Answer 4

a coiled tube atop each of the testes that provides for storage, transit, and maturation of sperm, continues with the vas deferens

Question 5

vas deferens, ductus deferens, or seminal duct

Answer 5

duct that carries sperm from epididymis to urethra

Question 6

seminal vesicles

Answer 6

2 main glands located posterior to the base of the bladder that open into the vas deferens. Glands secrete a thick fluid that forms part of the semen

Question 7

prostate gland

Answer 7

encircles the upper end of the urethra. secretes a fluid that aids in the movement of the sperm and ejaculation

Question 8

scrotum

Answer 8

sac containing the tests and epididymus

Question 9

glans penis

Answer 9

enlarged tip on the end of the penis

Question 10

prepuce

Answer 10

fold of skin covering the glans penis in uncircumsized males (foreskin)

Question 11

semen

Answer 11

composed of sperm, seminal fluids, and other secretions

Question 12

Flow of sperm

Answer 12

Formed in the seminerous tubules inside the testes, to the epididymis, to the vas deferens through the seminal vesicle and duct, to the urethra through the prostate gland and through the penis out of the body

Question 13

balan/o

Answer 13

glans penis

Question 14

orchid/o, orchi/o, orch/o, test/o

Answer 14

testis, testicle

Question 15

prostat/o

Answer 15

prostate gland

Question 16

vas/o

Answer 16

vessel, duct

Question 17

vesicul/o

Answer 17

seminal vesicle

Question 18

andr/o

Answer 18

Question 20

-ism

Answer 20

Question 21

erectile dysfunction

Answer 21

(ED) the inability of the male to attain or maintain an erection sufficient for intercourse (impotence)

Question 22

hydrocele

Answer 22

scrotal swelling caused by a collection of fluid

Question 23

phimosis

Answer 23

tightness of the prepuce (foreskin) that prevents its retraction over the glans penis

Question 24

prostate cancer

Answer 24

cancer of the prostate gland, usually occurring in men middle-aged and older

Question 25

spermatocele

Answer 25

scrotal swelling caused by distention of the epididymis containing abnormal cyst like collection of fluid and sperm cells

Question 26

testicular cancer

Answer 26

cancer of the testicles, usually occurring in men 15-35 years old

Question 27

testicular torsion

Answer 27

twisting of the spermatic cord causing decreased blood flow

Question 28

varicocele

Answer 28

enlarged veins of the spermatic cord

Question 29

circumcision

Answer 29

surgical removal of the prepuce (foreskin), all or part may be removed

Question 30

hydrocelectomy

Answer 30

surgical removal of a hydrocele

Question 31

radical prostatectomy

Answer 31

(RP) excision of the prostate gland with its capsule, seminal vesicles, vas deferens, and sometimes pelvic lymph nodes

Question 32

suprapubic prostatectomy

Answer 32

excision of the prostate gland through an abdominal incision made above the pubic bone and through an incision in the bladder and prostate capsule

Question 33

transurethral incision of the prostate gland

Answer 33

(TUIP) surgical procedure that widens the urethra by making a few small incisions in the prostate gland. No prostate tissue is removed

Question 34

transurethral microwave thermotherapy

Answer 34

(TUMT) treatment that eliminates excess tissue present in benign prostatic hyperplasia by using heat generated by microwaves

Question 35

transurethral resection of the prostate gland

Answer 35

(TURP) surgical removal of pieces of the prostate gland tissue by using an instrument inserted through the urethra

Question 36

azoospermia

Answer 36

lack of live sperm in the semen
