NCT ID NCT04705038
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether an educational session about orchiectomy (surgery to remove the testicles) would make more men with prostate cancer choose it over lifelong hormone therapy. 101 men who were already on hormone therapy for at least a year took part. The goal was to see how many would switch to the surgery after learning about it.
