Males and females between the ages of 18-65 are encouraged to participate in an online survey about male erectile dysfunction.

You are encouraged to participate even if you (or your partner) do not currently suffer from erectile dysfunction. This study is being conducted by Judith Easton of the Individual Differences and Evolutionary Psychology graduate program at The University of Texas at Austin.

The survey is simple and should not take longer than 30 minutes to complete.

Your responses in this experiment will be confidential. None of the responses you give during this survey will be linked to any information that could be used to identify you.

Your participation will contribute to a growing body of research relating to the adaptive nature of sexual behavior!

Your time in taking this survey is sincerely appreciated:
