Summary
This study investigates if denosumab improves sperm concentration in men with infertility. Results could offer new treatment options for male infertility, a condition with limited interventions.
Area of Science:
- Reproductive Endocrinology
- Male Infertility Research
- Clinical Trials
Background:
- Male infertility affects millions globally, often due to impaired semen quality.
- Current treatments for male infertility are limited, necessitating new therapeutic strategies.
- Denosumab, a RANKL inhibitor, shows potential for enhancing semen quality.
Purpose of the Study:
- To evaluate denosumab's efficacy in improving sperm concentration in men with severe male infertility.
- To assess the impact of denosumab on spermatogenesis using serum AMH levels as a predictive marker.
- To provide evidence for novel male infertility treatments.
Main Methods:
- A randomized controlled trial (RCT) involving denosumab versus placebo.
- Participants randomized in a 2:1 ratio to receive denosumab (60 mg subcutaneously) or placebo.
- Primary outcome: difference in sperm concentration after one spermatogenesis cycle (80 days).
Main Results:
- This section is for results, which are not yet available as the study is planned.
- The study aims to determine if denosumab significantly increases sperm concentration.
- Further analysis will focus on the impact on spermatogenesis.
Conclusions:
- This planned RCT will investigate a novel therapeutic approach for male infertility.
- Results are expected to inform future treatment strategies for men with severely impaired semen quality.
- The study addresses a critical unmet need for effective male infertility interventions.
