Characterization of patients in a medical endocrine-based center for male sexual dysfunction.

Objective: To characterize the patient population in a multidisciplinary sexual dysfunction clinic whose focal person is an endocrinologist and to summarize the initial manifestations, the demographics of the study group, and their associated medical conditions.

Methods: We undertook a retrospective analysis of the medical records of all new consultations in a center for sexual function during a recent 2-year period.

Results: During the period from July 1995 to July 1997, 1,050 men were seen in new consultations for sexual dysfunction at our medical facility, and complete medical records could be retrieved for 990 of them. Of the overall study group of 990 men, most (93.2%) had erectile dysfunction (versus libido or ejaculatory problems), but combinations of problems were common. Most men had organic causes of their sexual dysfunction that correlated with increasing age; however, their dysfunction was more often the result of chronic medical conditions than of advancing age itself. Most men were married (72.1%) and in long-term relationships (mean duration, more than 20 years). Hypogonadism was the most common medical condition (36.3%), a finding that reflected an endocrine referral bias. Testosterone treatment alone corrected the complaints in a minority of patients. Hypertension was a more common diagnosis than diabetes (35.8% versus 23.1%), and pituitary tumors were rare. Successful outcomes were achieved in about two-thirds of men having a strong organic cause of sexual dysfunction, but treatments were less successful when pronounced psychologic factors were present. The patient dropout rate was substantial and was similar in each of the four 6-month quarters--an indication that even as newer therapies became available, dissatisfaction was still evident.

Conclusion: Many patients have more than one manifestation of sexual dysfunction, which may have to be addressed separately. In a sexual dysfunction clinic managed by an endocrinologist, referral bias may direct more patients with hypogonadism and fewer patients who have had transurethral retropubic prostatectomy or a radical prostatectomy. Treatment of hypogonadism corrects sexual dysfunction in only a few men, and only when other medical problems are not present. Although the percentage of men with diabetes would be expected to be high in this study, the number of patients with hypertension was higher. A considerable dropout rate during evaluation and treatment persisted throughout this study.
