where glans meets penile shaft
corpus cavernosum, corpus spongiosum
cavernosum more outside layer, spongiosum more inside layer of shaft (surrounds urethra)
scrotal wall
rugae, cremaster muscle (contracts with cold, relaxes with heat)
lies top and posteriolateral to testis; transports sperm via ducts; connects to vas deferens
fetal sex differentiation & male development
differentiation by 12 wks; testes descend in 3rd t (retroperitoneal to inguinal canal to scrotum)
male puberty: onset, 1st sign, duration
9.5-13.5 yo; testicular enlargement 1st, then hair development & penile enlargement; 3 years
sexual changes after 55-60 yo
longer to achieve erection, maintain erection longer wo ejaculation, less intense orgasm, rapid detumescence & longer refractory state, grey pubic hair, penile size decreases, scrotum more pendulous
urinary complaints for men
dysuria, frequency, urgency, nocturia, hesitancy, straining, urine characteristics, incontinence
penile complaints
pain, lesions, discharge
scrotal complaints
pain, swelling, masses
inguinal complaints
pain, enlargement
presentation: painless enlarged scrotum; usu happens congentially boys 1-2 yo or secondarily men >40; fluid accumulates superior and anterior to testes; usually associated with hernias, usually unilateral
dilation of pampiniform venous plexus in scrotum; impairs sperm production probably through thermoregulation
foreskin of uncircumsized male cannot be retracted; usually physiological in infants; pathological in older children and adults who were previously about to retract foreskin
retracted foreskin cannot be put back in original location; can be medical emergency if blood flow is compromised
inflammation of glans penis due to poor personal hygiene; can result in phimosis
undescended testicle, empty scrotal sac
epididymal retention cyst, thin milky fluid containing sperm
direct inguinal hernia
through external ring, doesn't usually enter scrotum
indirect inguinal hernia
through internal ring, most common type, can remain in canal or enter scrotum
femoral hernia
herniation through femoral ring and canal, below inguinal ligament
anus anatomy--length & innervation
2.5-4.0 cm, lower half somatic sensory nerves, upper half autonomic non-sensitive
internal, external sphincter
internal, involuntary; external, voluntary
anal columns
columns of Morgani, anorectal juntion, each column has vein & artery
site of internal hemorrhoids
upper anal columns with vein & artery
site of external hemorrhoids
lower anal canal with venous plexus
rectal physiology
12 cm long, highly innervated (any rectal trauma painful)
rectal ampulla
just above anal canal, rectum dilates and turns posterior, stores flatus & feces
valves of houston
3 semilunar transverse folds, lowest palpable on left
fetal development
rectum by 7 wks, patent anus by 8 wks
infants development
internal & external sphincters involuntary until spinal cord maturity by 18-24 mo.
pilonidal cyst
cyst in sacrococcyeal area believed to be result of hair entering skin & causing inflammatory process
median sulcus
middle of prostate
seminal vesicles
extend out & above prostate, secrete fructose to nourish sperm
cowper's gland
inferior to prostate, either side of urethra, size of pea, secrete fluid for semen transport
What might you feel on prostate?
boggy: infection, rubbery/boggy: BPH,
hardness/mass: cancer, fibroid, stone
prostatitis-acute (bacterial)
chills, fever, pain in lower back or genital area, urinary frequency often at night, similar to UTI
very rarely bacteria. Most of the time pelvic pain of unknown cause (CP/CPPS). Distinguis bt BPH by pain after ejaculation with CP.
