Study Summary
Investigate the effect of intratesticular injection of autologous platelet rich plasma (PRP) on sperm retrieval rates and IVF outcomes in infertile men who already underwent a negative sperm retrieval. Currently, there is no alternative treatment after failed TESE. Prior series suggest that intratesticular PRP injections may improve TESE outcomes. We hope to determine whether PRP is an effective treatment for this patient population.
Primary Outcome
A TESE procedure will be performed to determine if sperm are present
