Testicular or Epididymal Sperm Extraction (TESE or PESA)
Testicular or epididymal sperm extraction is typically performed when there is a blockage in one of the tunnels that sperm swim through. This can be seen after vasectomy, after some groin surgeries, or from a blockage that some men are born with. Since the issue is from a blockage (and not an issue with sperm production), we can extract sperm directly from the testicle or epididymis with a needle. The procedure is coordinated with an IVF cycle, to when the female partner is ready for egg retrieval. This is oftentimes done at the individual fertility center that the female partner is working with. It may be done with local anesthesia or with an IV sedative.
