Summary

This study follows 1,000 young men (ages 15-39) diagnosed with cancer to understand how treatments affect their fertility and hormone levels over time. Researchers will collect medical history, semen samples, and blood tests before and after therapy to identify who is at risk for infertility or low testosterone. The goal is to create personalized care plans to help survivors manage their reproductive health.
