Summary

This trial is testing whether testosterone replacement can help improve pain perception, pain tolerance, sexual function, fatigue, and quality of life in men with chronic back pain being treated with opioids who have low testosterone due to their opioid use.

Who is the study for?
This trial is for men over 18 with chronic back pain treated with opioids, leading to low testosterone levels. They must have been on opioid painkillers for at least six months and be willing to consent. Men with prostate or breast cancer, certain mental health conditions, recent heart issues, severe kidney or liver disease, or specific metallic implants cannot participate.
What is being tested?
The study tests if testosterone replacement (Testosterone Undecanoate) can better improve pain perception, tolerance, sexual function, fatigue and life quality compared to a placebo in these men.
What are the potential side effects?
Potential side effects of Testosterone Undecanoate include acne, changes in sex drive or performance, hair loss or growth on the body/face and mood swings. More serious risks may involve blood clots and heart problems.
