This trial is for male patients of any age who may become infertile due to a medical condition or treatments that are harmful to reproductive cells. It's specifically aimed at those for whom freezing testicular tissue is the only option to preserve fertility.
What is being tested?
The study focuses on taking a small sample of testicular tissue and freezing it (cryopreservation) with the goal of preserving future fertility. The feasibility and acceptability of this procedure in patients at risk of infertility will be evaluated.
What are the potential side effects?
Potential side effects might include discomfort, bruising, or infection at the biopsy site where tissue is taken from the testicles. Long-term effects are uncertain since this is an experimental procedure.
