What this trial studies

This pilot study investigates the effects of sex hormone therapy on healing after rotator cuff repair surgery in men with low hormone levels. Participants will be randomly assigned to receive either clomiphene citrate, which stimulates the body to produce testosterone and estrogen, or a placebo while recovering from surgery. The study aims to determine if increasing hormone levels can enhance tendon healing, reduce pain, and improve shoulder function. The research is based on the hypothesis that hormone deficiencies may contribute to both the occurrence of rotator cuff tears and the failure of surgical repairs.

Who should consider this trial

Good fit: Ideal candidates are men planning to undergo primary rotator cuff repair with a full thickness tear greater than 1 cm.

Not a fit: Patients with active infections, pre-operative testosterone supplementation, or certain medical conditions such as untreated prostate cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved healing and function for patients recovering from rotator cuff surgery.

How similar studies have performed: While this approach is novel in the context of rotator cuff repair, previous studies have suggested that hormone therapy may have beneficial effects on tendon healing.
