Testicular Sperm Aspiration (TESA)

Testicular Sperm Aspiration (TESA), also known as Testicular Fine Need Aspiration (TEFNA)

TESA is performed under local anesthesia and is usually the method chosen for males with OA who are retrieving sperm for IVF/ICSI.  The timing of the procedure will usually be coordinated with their female partner’s ovulation, occurring on the same day as her egg retrieval. TESA uses a needle, inserted into the testicle, to aspirate tissue into a syringe.  The tissue is then analyzed for its sperm content and quality, and IVF can be directly performed.

While it is minimally invasive and simple, TESA is not the most efficient method of retrieval and may cause damage to the testicular tissue.
