A retired researcher friend asked for my help. He has been linking male sex hormones to behavior for more than three decades. Since he is retired, he has no access to students to volunteer as research participants. I can't help him because there is no way the IRB committee at my university will approve this study. He needs volunteers to complete this 5 minute survey. Please help if you can, and invite others. We need the broadest sample we can get. Warning: you will need to measure a body part! https://www.surveymonkey.com/r/NKBRYYR
UPDATE: Of course, this study is very exploratory. He wants to see if it looks promising.
