Penile Circumference and condoms -Appendix: The Kinsey Data
Subjects. Descriptive statistics are provided for the data of 4 studies. In Table 2 the following characteristics are presented: subject group (sexually dysfunctional versus sexually functional men), the kind of sexual stimuli used, number of subjects (N), number of subjects with estimations of degree of erection available, number of subjects with estimated degree of erection > 0%, number of subjects with more than 0 mm circumference change, number of subjects with NPT > 0 mm circumference change (study 3).
Subjects from study 1 were patients with complaints of erectile failure. Subjects from study 2-4 were sexually functional men. Both patients and control subjects submitted written informed consent prior to participation. Confidentiality, hygiene, privacy during the psychophysiological session, and the opportunity to withdraw at any time were assured to all subjects. Subjects were assessed individually.
(>0% estim erect.)
(>= 1mm change)
(>= 1mm NPT)
The mean age of the subjects in study 1 was 53 (range 19 to 78 yrs). The mean age of the subjects in study 2 was 40 (range 19 to 69 yrs). The mean age of the subjects in study 3 was 27 (range not available). At the time of writing this report, information was not available concerning the age of the subjects in study 4. Most subjects were white (college- and non-college) heterosexual men. Only a few homosexual men participated in the four studies. These men were provided with stimuli matching their sexual preference.Stimuli. In study 1 and study 2, several 3-min. sexual film excerpts were used as stimuli. For the purpose of this report the data of only one film presentation is presented. In study 3, subjects were presented with a 10-min. sexual film excerpt or with two 5-min. sexual slides. Subjects in study 3 also measured their erections at home. These subjects were instructed to place the Erectiometer on the penis before going to sleep. Thus, for this group additional data was obtained concerning sleep-erections ('nocturnal penile tumescence', NPT).
