183 Evaluation of Ejaculation Function Using a Simple Questionnaire

Abstract

Introduction There is a wide range of problems associated with ejaculation, including decreased semen volume, vaginal ejaculation problems, premature ejaculation, delayed ejaculation, hematospermia, and pain associated with ejaculation. However, there is no simple questionnaire that can comprehensively evaluate these ejaculatory functions. Objective In this study, we evaluated the overall ejaculation function of the patients in question using an originally developed ejaculation function score (Kimura and Shoji's Ejaculation Function Score). Methods We examined 20 patients who visited our sexual function outpatient clinic with a chief complaint of ejaculation. As a control group, we also examined 20 patients who had undergone vasectomy using the same score. The questionnaire consisted of the following five items (1) Awareness of sufficient momentum, (2) Pleasant sensation during ejaculation, (3) Presence of pain associated with ejaculation, (4) Presence of blood in semen, and (5) Perception of decreased semen volume. The total score was also evaluated. In addition, satisfaction with the current ejaculation was assessed. Results The mean age of the ejaculation disorder group was 43.5±15.1 years. The main complaints were decreased semen volume in 7 cases (35%), vaginal ejaculation disorder in 6 cases (30%), delayed ejaculation in 2 cases (10%), premature ejaculation in 2 cases (10%), lack of orgasm in 1 case (5%), and pain associated with ejaculation in 1 case (5%). The mean scores for each item were 1.5 for item 1, 1.8 for item 2, 3.0 for item 3, 3.0 for item 4, and 2.0 for item 5, resulting in a mean total score of 11.2. On the other hand, the mean age of the vasectomy group was 42.0±9.4 years, item 1 was 2.8, item 2 was 2.9, item 3 was 3.0, item 4 was 3.0, item 5 was 2.9, and the mean total score was 14.6. When the two groups were compared, significant differences were found except for items 3 and 4. There was also a significant difference in satisfaction of present ejaculation with mean scores of 1.3 and 2.9. As a result of examining the clinical severity and the total score, the total score of 5-6 was considered severe, 7-9 moderate, 10-13 mild ejaculation disorder, and 14-15 within the normal range. Conclusion Although our ejaculation function score is still in the developmental stage, we believe that it can be a screening tool for ejaculation function in practical medical care and self-assessment.
