To confirm the effect of SS-cream, which was based on the traditional Chinese Royal herb remedy including 8 oriental herb combinations, 43 out of 150 patients with premature ejaculation (PE) were selected and investigated for a double-blind clinical trial between Nov. 1993 and Feb. l994. There mean age was 41.4 years. The 28 patients complained of PE only but 15 had concurrent mild psychogenic impotence. Only 20% of their spouse was satisfied for sexual lives. The packages of SS-cream and controls such as 1.25% (LL), 5%(ML) and 10%(HL) lidocaine cream were made similarly as much as 0.2g. They were randomly divided into the 5 groups. Each patient was assigned to apply LL, ML or SS cream once a weak for 4 consecutive weeks as scheduled. A within subjects comparison of pre and post application for ejaculation time and spouse's satisfaction was investigated. The applied groups such as LL, ML and HL cream were not effective. After SS-cream application, ejaculation time was delayed upto mean 11.3min. in 40(93%) and most of them with PE only as well as PE associated with impotence were satisfied. These data suggest that SS-cream is effective in treating PE as well as PE with mild impotence.
