Looking for Participants for a Testosterone Study Survey

I appreciate Nelson for approving this post/link

Thank you for viewing this post. I'm a 4th year Urology resident performing a study concerning the current usage patterns of testosterone, associated ergogenic aides, and potential side effects including fertility outcomes.

To be a candidate for the study you must be a male (18+) with a history of testosterone use (in any form with or without other AAS) for any period of time. The demographic I'm attempting to capture from this forum are those on self-TRT, not managed by a physician and men who self supplemented with T and were later diagnosed with low T leading to the need for physician directed TRT.

This is not an anti-steroid study, we are merely looking at usage patterns, reasons for use, and our primary interest is future fertility since we see many similar patients in clinic. The study is an anonymous 5 minute survey. No future contact will be made with study participants and there's no legal liability. I would greatly appreciate your time and participation. Feel free to post any questions in this thread and I will address them as promptly as possible. When the results are in and I have the manuscript written, I'll be sure to share them with all participating forums.

Please take the survey posted in the first post to finish up the last 15 if you
have time.

Greatly Appreciated,

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
