RecruitingDevice studyIntelliWell: An AI-Assisted Imaging Platform for Detection and Location of Ultra-Rare Testicular Sperm in Surgical SpecimensThis study will help determine whether an AI-assisted microwell platform (IntelliWell) can identify rare sperm cells in testicular samples found to not have sperm by conventional analysis. Instead of discarding testicular tissue which was found to be non-sperm bearing by conventional analysis the testicular tissue will be processed using IntelliWell and, if sperm is found and verified by embryologists, it may be used for intracytoplasmic sperm injection (ICSI).
