What are the name, quantity and location of the 3 cylindric columns of erectile tissue in
the penis? - ANSWER Two corpora cavernosa on the dorsal side and the corpus
spongiosum ventrally
What is located at the distal end of the shaft the corpus apongiosum and expands into a
cone of erectile tissue? - ANSWER the Glans
,What is the shoulder where the glans joins the shaft? - ANSWER Corona
What is the passageway for both the reproductive and urinary systems AND runs
through the corpus spongiosum and its opening forms a slit at the tip of the glans? - ANS
Urethra
What is covering the glans and the skin folds in and back on itself, forming a hood or
flap- is often surgically removed shortly after birth due to circumcision? - ANS Foreskin
AKA prepuce
What is a loose protective sac which is a continuation of the abdominal wall? - ANSWER
Scrotum
What is the thin skin lying in folds in the scrotal wall and after adolescence the scrotum
becomes deeply pigmented and has large sebaceous follicles? - ANSWER Rugae
What controls the size of the scrotum by responding to ambient temperature? -
ANSWER Cremaster muscle
Elevates and descends to keep the testes a 3 degrees C below abdominal temperature
which is best temperature for producing sperm
What is the name of the scrotal halves that produce sperm? - ANSWER Testis
What is the shape of the testes and dimensions? - ANSWER Solid oval shape which is
compressed laterally and measured 4-5 cm long by 3 cm wide in the adult
What is the Coiled duct system that caps the testicle and transports and stores sperm
that is produced in the testis? - ANSWER Epididymis
,What is mascular duct that combines with other vessels to form the spermatic cord,
runs up the inguinal canal of the abdomen, behind the bladder where join the seminal
vesicle to form the ejaculatory duct that empties into the urethra? - ANSWER Vas
deferns
What is the groove in the juncture of the lower abdominal wall and the thigh, holds the
inguinal canal, a narrow tunnel passing obliquely between layer of the abdominal
muscle, 4-6 cm long in adult? - ANSWER Inguinal area
What are some developmental differences in the infants male genitalia? - ANSWER
Infants:
- prenatally the testes develop in the abdominal cavity near the kidneys
-in later months of gestation, the testes migrate, pushing abdominal wall in front of them
and dragging the vas deferens, blood vessels, and nerves behind
- testes descend along the inguinal canal into the scrotum before birth
- At birth, the testes measure 1.5-2 cm long and 1 cm wide
- Only a slight increase in size occurs during prepubertal years
What are some developmental differences in the aging adult male genitalia? - ANSWER -
older man doesn't experience a definite end to fertility as the women does
- production of sperm decreases around 40 y/o, although continuing in 80s - 90s
- testosterone productions decline after age 30 but very gradually, so resulting physical
changes are not evident until later
- amount of pubic hair decreases and turns gray
- penis size decreases
- scrotal contents hang lower because of decreased tone of dartos muscle, the rugae
decrease and scrotum appears pendulous
- testes decrease in size and less firm to palpation
- prostate gland surrounding the upper urethra undergoes expected tissue hyperplasia
in about 80% of men over 60 y/o
- Although not cancer, BPH (benign prostatic hyperplasia ca\
, uses obstructed urine stream and risk for UTI
- d/t decrease testosterone older male has slower and less intense sexual response and
erection takes longer to develop and is less firm or full
-ejaculation is less shorter and less forceful and the volume of seminal fluid is less than
when the man was younger
- after ejaculation, rapid detumedence (return to flaccid state) occurs- usually after 60
y/o
What is the sexual expression later in life for males? -ANSWER-chronological age itself
shouldn't mean halt in sexual activities
-sexual changes need not interfere with libifo and pleasure derived from sexual
intercourse
in absence of a disease, withdrawal from sexual preoccupation with work, martial, or
family conflict, side effects of medications antihypertensives, psychotropics,
antidepressants, antispasmodic, sedatives, tranquilizers or narcotics, and estrogen),
heavy use of alc., lack of privacy, economic or emotional stress, poor nutrition, or
fatigue
What are the advantages of circumcision of the male newborn? - ANSWER - lesser
chance of acquiring HIV infection through heterosexual contact
• The AAP suggests that the health benefits of newborn male circumcision outweigh the
risks
• To be an insurance-covered and Medicaid-covered procedure
• Infant: UTI risk is reduced
• Adult: STIs reduced in risk [HPV, herpes simplex virus, and genital ulcer disease in
men], bacterial vaginosis risk in female partners, trichomoniasis risk in female partner
What are the cons to circumcision in the male newborn? - ANSWER - non therapeutic
surgical procedure with small but possible risk for complications
- most are minor and treatable (pain, bleeding, swelling, or inadequate skin removal)
- review of adverse events of male circumcision in US medical settings found incidence
at less than 0.5% during infancy, but adverse events increased when performed in older
ages
