Hormone shot timing may affect recovery after prostate cancer treatment

This trial compares two types of hormone injections given before prostate brachytherapy (internal radiation) for early-stage prostate cancer. One injection lasts one month, the other three months, and both are used to lower testosterone to make radiation more effective. The study measures how quickly testosterone returns to normal after treatment, as well as PSA levels, quality of life, and sexual function. Participants are men with localized prostate cancer who are already recommended to receive hormone therapy as part of their brachytherapy plan.
