Re: Effect of testosterone replacement on response to sildenafil citrate in men with erectile dysfunction: A parallel, randomized trial

摘要

This randomized, double-blind, placebo controlled study compared 59 men who took placebo and 59 who took 1,400 mg Korean ginseng berry daily for 8 weeks, and examined changes in sexual function due to the ginseng. Data were analyzed at 4 and 8 weeks. Erectile function improved slightly at 8 weeks (p = 0.046) but not at 4 weeks. There were small but statistically significant changes in intercourse satisfaction, orgasmic function and sexual desire at both time points. There were no reported changes in testosterone, cholesterol or prolactin levels. Blood pressure was not reported. At face value it seems that 1,400 mg oral ginseng daily has no significant downside/risks and offers a slight improvement in various aspects of sexual function noted as early as 4 weeks.
