NAPO - Novel Approach for Oligospermia
- Registration Number
- NCT06300229
- Lead Sponsor
- Martin Blomberg Jensen
- Brief Summary
This randomized controlled trial aims to assess whether treatment with denosumab can improve semen quality in infertile men selected by serum anti-mullerian hormone (AMH) as a positive predictive biomarker, and with severely impaired semen quality (concentrations between 0.01 million/mL to 2 million/mL).
- Detailed Description
Infertility is a common problem globally and impaired semen quality is responsible for up to 40% of all cases. Despite the high prevalence there are currently only very limited treatment options to improve semen quality for infertile men. Instead, almost all infertile couples are treated with inseminations or assisted reproductive techniques (ARTs) independe...
