Palpation Penis
Assess for tenderness, pulsations, masses Urethral meatus
Assess for discharge Scrotum
Assess for masses, tenderness, spermatic cord Inguinal area
Assess for hernias Abnormal findings
Copyright 2002, Delmar, A division of Thomson Learning
Palpation: Abnormal Findings Vascular insufficiency Penile edema Urethral discharge Spermatocele Cryptorchidism Orchitis Scrotal edema Hernias

Auscultation Scrotum Abnormal findings
Presence of bowel sounds may indicate indirect inguinal hernia
Copyright 2002, Delmar, A division of Thomson Learning
Gerontological Variations Thinner pubic hair Decreased testosterone levels Penile and testicular atrophy Slightly decreased spermatogenesis Increased time to obtain erection Increased risk for impotence
Copyright 2002, Delmar, A division of Thomson Learning
Normal Findings Triangular shaped distribution of
pubic hair Penile skin is free of lesions and
inflammation Penile shaft skin is loose and
wrinkled Foreskin retracts easily
(continues)
Copyright 2002, Delmar, A division of Thomson Learning
Normal Findings No discharge from foreskin Scrotal skin is pigmented,
rugated, and thin No lesions, nodules, swelling, or
inflammation are present in the scrotal area
Left scrotal sac is lower than the right

Copyright 2002, Delmar, A division of Thomson Learning
Normal Findings No bulges or swelling are present
in the inguinal area Penis is nontender Able to palpate a pulse on the
dorsal side of the penis Urethral meatus is free of
discharge
(continues)

Normal Findings Testicles are firm, ovoid, smooth, and
equal in size Spermatic cord is smooth and round Small, freely mobile lymph nodes are
present in the inguinal area The inguinal area is free from bulges
or palpable masses No bowel sounds are present in the
scrotum

Special Techniques Androscopy
Used to identify skin lesions Urethral culture
Used to identify causative organism of penile discharge
Transillumination of the scrotum Used to determine the etiology of a
scrotal mass
