The room should be Male Anatomy warm enough for the patient to be comfortable. The patient should be asked if the room is warm enough. This is especially important in examining the elderly, since they may be less tolerant of the cold. The warm room will also avoid activation of the cremasteric reflex that causes the testes to ascend from the scrotum upward toward the pelvic cavity (Pulsifer, 2005). This reflex can also be provoked by touch. If possible, interrup- tions should be avoided after the examination is begun. INSPECTION Source: Marieb, 2006.

A direct inguinal hernia would be near the external inguinal ring, while an indirect inguinal hernia would be at the internal inguinal ring (see Figure 2). Penile growth rate is progres- sive and predictable (see Table 4). An abnormally small penis may be indicative of a clitoris, Klinefelter’s or Down’s syndrome (Gomella, 2002).
