Clinical reviews and large retrospective studies consistently demonstrate that testosterone and anabolic-androgenic steroid use increases the risk of musculoskeletal complications, specifically tendon injuries and ruptures.
The retrieved literature contains specific clinical studies and reviews directly evaluating the relationship between testosterone replacement therapy or anabolic steroid use and tendon injuries. Paper [3] provides strong direct evidence via a large retrospective cohort showing increased odds of Achilles tendon injury and surgery with testosterone therapy, while paper [10] reviews how anabolic-androgenic steroids disrupt collagen balance and increase tendon rupture risk. Paper [0] broadly supports the link to musculoskeletal disorders. No papers refute the claim.
