Some domestic sexual surveys pay attention to the number of samples, ignoring the investigation process and data analysis The tendency of process methodological problems. In fact, the sample is too large, but prone to error. The authors before the case of several sexual dysfunction survey and outpatient case analysis, samples are hundreds, but because of the existence of certain methodological issues, the paper declined significantly in value. Some of the methodological issues raised in this paper are only some of the more common problems in clinical studies of sexual function in China. The author is here to initiate discussion with a view to arousing discussion and criticism. First, the sampling problems 1. Sample representative dysfunction survey often take a sampling method, trying to draw the law from a limited sample, and then infer the overall. In order to reduce the sampling error as much as possible, the samples required are representative and can be roughly estimated
