The digit length ratio of the second finger length to fourth finger length (2D∶4D) is a putative marker for prenatal androgen action, exists sexual, ethnic, racial, and geographic differences,is associated to the incidences of diseases and may pre-estimate physical capacity potential. This study reviewed publications on digit ratio over the past decade and analysed their publication time, professional distribution and impact factors. It indicated that the major publications came from British, United States, Austria and Germany and few from China. In addition in humans, digit ratio was studied in the primates. The digit ratio, as a anthropometry index, still is a hotpoint as it is important to estimate health risk factors, prevent some diseases, study human behavior and cognizence and so on. In the future, it needs to be probed thoroughly in differences of intergroups digit ratio, animas digit ratio, applications in medicine, sport science, behavior science and foundation m
