Productivity Index in Clinical Andrology: Research Directions on High-Impact Topics and in Particular on Male Infertility.

As could be expected, we observed that prostate cancer and male infertility were the two most investigated topics, followed by benign prostatic hyperplasia and erectile dysfunction, whose prevalence is set to increase given the progressive aging of the population. Less investigated is the inflammation of the accessory sexual glands. In conclusion, this study provides a ranking of the main andrological topics investigated in the literature, also presenting the top list of the most productive authors for each one.
