|THE INSTRUMENTS REQUIRED FOR THE TESA|
TESA (testicular sperm aspiration), which is performed by sticking a needle in the testis and aspirating fluid and tissue with negative pressure.
We routinely perform TESA in our hospitals.Our approach has been to go for Microdissection TESE in cases of small atrophic testes with high FSH or failed TESA.
We use 18 G scalp vein and we pierce the testis and move the needle in to and fro fashion at the same time the assistant withdraws a negative suction with a plunger of 20 cc syringe.
The testicular tissue beutifully comes out and can be used for IVF purpose/ cryopreservation and also for the histopathological analysis.We stress upom all the patients for cryopreservation.In cases where the testis is smaller in volume with higher FSH ; we go for multiple TESA .The success of TESA has been excellent even in cases of Non Obstrictive azoopsemria with borderline high FSH.This is a good alterbative for Microdissection TESE where the microscopy or expertise for the same is not available.
