Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This 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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

IntelliWell Arm

Group Type EXPERIMENTAL

Use of IntelliWell to identify and localize sperm for ICSI

Intervention Type DEVICE

The experimental arm will have surgically extracted testicular sperm processed with IntelliWell. If identified and confirmed by embryology, cryopreservation of sperm will occur. On day of ICSI, thaw of testicular sperm will occur and be processed by IntelliWell for identification and localization for use in ICSI.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male subjects presenting to Brigham and Women's or Faulkner urology clinic with infertility with clinical non-obstructive azoospermia (clinical diagnosis based on two semen analyses, physical examination, and hormonal testing).
2. Male subjects undergoing micro-surgical testicular sperm extraction surgery at Brigham and Women's Hospital.
3. Surgically extracted sperm which are not found to have clinically usable quantities of sperm after standard of care manual processing for which samples would otherwise be discarded and the procedure deemed unsuccessful.

Exclusion Criteria

1\. Female subject (with whom male subjects intends to conceive with surgically extracted sperm) cannot or will not provide her informed consent for study participation. She will undergo ICSI at BWH with BWH embryology.
