(183) FROM WATERLOO TO THE GREAT WALL: A RETROSPECTIVE, MULTICENTER STUDY ON THE CLINICAL PRACTICE AND CULTURAL ATTITUDES IN THE MANAGEMENT OF PREMATURE EJACULATION, IN CHINA.

Objectives: To carry out a real-life retrospective, multicenter survey on the prevalence, subtype, and proposed treatments of premature ejaculation in China. Methods: Real-life data were provided by 8 major Centers from China, selected as active in basic and clinical research on PE and participating to international meetings of sexual medicine and andrology. Centers provided a filled survey containing relevant information concerning PE prevalence, pathogenesis and treatment. Results: In 2019, among 156,486 patients coming to the centers, 32,667 visits having PE as the chief complaint were performed (20.9%). Almost all patients received treatment prescriptions (32,641 patients, 99.92%); 23,273 patients came back for a follow-up visit in the subsequent 12 months (71.2% of those who initially received treatment). Dapoxetine, either alone or in combination with another therapy, was the most prevalent treatment, prescribed to 22,767 patients (69.7% of treated patients), followed by Traditional Chinese medicine (TCM) (39.4%). At follow-up, 8174 patients were unsatisfied with treatment, and a new treatment was proposed (35.12%). Dapoxetine was the best treatment, with an overall 27.1% switching rate when used either alone or in combination: while the switching rate for Dapoxetine alone was 44.2%, the association of the same drug with psychotherapy resulted in much lower rates (19.5%) and reached a minimum of 12% when also combined with TCM demonstrating how cultural aspects and medical attitudes may dramatically impact on the therapy of a multifaceted, complex, and culture-grounded sexual symptom such as PE. Conclusions: Taking switching rates as surrogate markers of treatment failure, this real-life study – the largest in the field - shows that in a more patient-oriented (as in Chinese medical culture), and less symptom-oriented (as in Western medical attitudes), Dapoxetine is a successful treatment for PE patients, with higher reliability when used alone or as part of combined and integrated therapies.
