The Claim

Systemic supplementation with estrogen or testosterone in adult male mice following surgical repair of the supraspinatus tendon improves the histological structure of the repaired enthesis site at 8 weeks post-surgery.

Cause and effect
1 study reviewed
In plain English

In adult male mice after supraspinatus tendon surgery, treatment with estrogen or testosterone results in improved histological structure of the tendon attachment site at 8 weeks.

See the scientific wording

In adult male mice following surgical repair of the supraspinatus tendon, systemic supplementation with estrogen or testosterone improved the histological structure of the repaired enthesis site at 8 weeks post-surgery, suggesting these hormones may influence tendon healing processes.

Why this might work

Estrogen or testosterone enters the body and binds to receptors in cells at the tendon-bone junction, turning down genes that cause inflammation. This reduces harmful chemicals in the tissue, allowing the tendon to rebuild its connection to bone with better-organized collagen and fibrocartilage.
