Aim: To assess the efficacy and safety of tadalafil in comparison to a placebo, when taken on demand for 12 weeks by East/Southeast Asian men with erectile dysfunction (ED).

Methods: This multicenter, randomized, double-blind, parallel group, placebo-controlled study was conducted at 17 centers across East and Southeast Asia between August 2002 and February 2003.

Lower urinary tract symptoms and male sexual dysfunction in Asia: a survey of ageing men from five Asian countries.

Objective: To determine, using the Asian Survey of Aging Males (ASAM), the prevalence of lower urinary tract symptoms (LUTS) and sexual disorders in Asian men aged 50-80 years, and to investigate the relationship between LUTS and sexual dysfunction, as community-based studies have shown a relationship between LUTS and sexual dysfunction.

Subjects And Methods: The ASAM survey was conducted in selected cities in five Asian countries, using a combination of face-to-face and mail-survey methods. The survey evaluated demographics, urinary symptoms (using the International Prostate Symptom Score, IPSS, and bother score), functional problems (using the Danish Prostatic Symptoms Score, DAN-PSS-Sex, and International Index of Erectile Function, IIEF) and comorbidity factors.
