Male Genitourinary Exam
1. what three columns of vascular erectile tissue form the penis shaft?: -cor- pora cavernosa (x2)
-corpus spongiosum
2. what does the corpus spongiosum contain?: the urethra
3. where does the corpus spongiosum extend to?: from the bulb of the penis to the glans
4. what is the hood-like fold of skin that covers the glans in uncircumcised males called?: prepuce aka foreskin
5. smegma: a collection of shed skin cells and oils; may collect in the foreskin
6. where is the urethra located?: in the *ventral midline* of the shaft, opens into a vertical slit-like urethral meatus
7. what does the testes consist of?: *seminiferous tubules*, cover coating called the *tunica ed by a
albuguinea* fibrous
8. what kind of cells do the testes contain and what do they produce?: leydig cells that produce testosterone in
response to LH
9. gonadotropin-releasing hormone is produced by the to stimulate
production of and .: pituitary gland, LH and FSH
10.what are the size of the testes in prepubertal boys and postpubertal boys?: 1.5-2 cm
4-5 cm
11.what are the structures surrounding the testes?: -scrotum
-tunica vaginalis
-epididymis
12.tunica vaginalis: serous membrane that covers testies (not posteriorly) and originates from peritoneum of the
abdomen brought down into the scrotum during
*testicular descent* through the internal inguinal ring
13.epididymis: located on posterolateral surface of each testicle, consists of *tight- ly coiled tubules* (palpable
nodules) emanating from the testes that become the vas deferens
14.what does the epididymis function as?: a reservoir for sperm storage, matu- ration, and transport
15.where does lymph drain from the penis?: to the deep inguinal and external inguinal nodes
16.where does lymph from the scrotum drain?: superficial inguinal lymph nodes
, Male Genitourinary Exam
17.basic landmarks of the groin: -anterior superior iliac spine
-pubic tubercle
-inguinal ligament that runs between ASIS and public tubercle
18.importance of knowing the groin's landmarks: to identify hernias (very com- mon in men)
, Male Genitourinary Exam
19.where is the *inguinal canal* and what does it consist of?: -lies medial to & roughly parallel with the inguinal
ligament
-consists of internal and external inguinal ring
20.what is the inguinal canal?: a tunnel for the vas deferens as it passes through the abdominal muscles
21.internal inguinal ring: approximately 1 cm above the midpoint of the inguinal ligament
22.external inguinal ring: triangular, slit-like structure palpable just above and lateral to the pubic tubercle
can feel a palpable hernia in this area with increased pressure during abdominal exam (coughing)
23.stage 1 sexual maturity rating: preadolescent
-no pubic hair
-penis, testes, and scrotum are same size as childhood
24.stage 2 sexual maturity rating: -sparse growth of long, slightly pigmented, downy hair
-slight to no enlargement of penis
-testes larger and scrotum somewhat reddened
25.stage 3 sexual maturity rating: -darker and courser hair spreading sparsely over *pubic symphysis*
-penis larger in length
-testes and scrotum further enlarged
26.stage 4 sexual maturity rating: -more coarse and curly hair, as in the adult,
*does not include thighs*
-penis further enlarged in length, development of the *glans*
-scrotum and testes further enlarged, scrotal skin darkened
27.stage 5 sexual maturity rating: -hair adult in quantity and quality, spreads to thighs but not upper abdomen
-penis, testes, and scrotum adult in size and shape
28.genitourinary changes in elderly men: -sexual interest intact, frequency of intercourse declines at age 75
-testosterone decreased
-testis decrease in size
-pubic hair decreased + greyed
-erectile dysfunction
