Who might be able to join this trial:
- You are a man being seen at Brigham and Women's or Faulkner urology clinic for fertility problems, specifically a condition where no sperm are found in your semen (confirmed through semen tests, a physical exam, and hormone tests)
- You are a man having a microsurgical procedure at Brigham and Women's Hospital to try to retrieve sperm directly from the testicle
- After your surgery, the sperm that was collected was not enough to be usable through the standard process, and the sample would normally be thrown away with the procedure considered unsuccessful
Who may not be able to join:
- The female partner (the woman you are hoping to have a child with using the surgically retrieved sperm) is unable or unwilling to give her consent to take part in the study, or she will not be having her fertility treatment (a procedure called ICSI) carried out at Brigham and Women's Hospital with their embryology team
