Males complaining of erectile and ejaculatory dysfunctions were treated in a structured therapy program. Twenty-one males of heterosexual, homosexual, or bisexual orientation were divided into five groups, with two male therapists for each group. Patients were those usually considered difficult to treat in that 16 had a primary sexual dysfunction with an average duration of 6 years. Extensive evaluations were made before therapy, at the completion of therapy, and at 2-months follow-up. Pre-therapeutic, post-therapeutic, and follow-up measurements indicated that the program was highly successful.
