title: The effects of testosterone administration and visual erotic stimuli on nocturnal penile tumescence in normal men.
abstract: Nocturnal penile tumescence (NPT), as circumference change and rigidity, and REM sleep were measured in eight normal eugonadal men in two controlled experiments. In the first, exposure to erotic film prior to sleep had no effect on frequency of REM or on NPT. In the second placebo controlled experiment 150 mg im testosterone enanthate administration was associated with enhanced rigidity of NPT but with no effect on frequency or circumference change of NPT and no effect on frequency of REM.
