TESA or testicular sperm aspiration

TESA is generally performed the day before the oocyte pick-up. It improves the sperm cells’ ability to fertilise if they have a day to mature after the testicular aspiration. The number of sperm cells obtained by TESA is always rather low. Therefore, ICSI is always necessary when fertilising the oocytes. 

Before ICSI is planned, the man will be tested to determine whether it is likely that sperm cells can be aspirated from the testicles. Despite
this it may rarely happen that no sperm cells can be obtained by TESA. 

Therefore, you should have thought about alternatives if this should happen. Should the oocytes be
fertilised with donor semen? Should they be cryopreserved for later use? Should they be donated to another couple? Or should they be discarded? 

TESA is performed under local analgesia on the scrotum and the procedure takes less than 30 minutes. If you prefer we can provide analgesia in the same way that we do for oocyte pick-up. 

It is common to have some tenderness in the testicle for a few days after the procedure.

Possible complications to TESA

Local bleeding or infection may complicate TESA in 1% or less of the procedures. The symptoms will be pain, swelling or fever. The treatment is with antibiotics. Contact an emergency medical service or us if you have signs or symptoms of a complication.
