There have been various approaches to the treatment of nonorgasmic women, including psychoanalysis, desensitization, relaxation, masturbation, and group therapy. The present study was conducted to examine the efficacy of group therapy combined with home-based training in the treatment of primary nonorgasmic women. A no-treatment control group was also employed. Treatment consisted of two weekly 1- hour group sessions for 5 weeks. Educative processes were employed, such as detailed information on physiology of female sexual response. Structured homework exercises were also utilized, such as mastubatory techniques, role-playing orgasm, strengthening vaginal muscles, and assertiveness training in sexual and nonsexual situations. Results indicated an 88% success rate in the treatment group and no change in the control group.
