TESA - Testicular Sperm Aspiration

Patients having Azoospermia (not able to produce sperms) can be treated with TESA. A needle is passed through the scrotal skin into the testicle. With syringe suction a very small amount of testicular tissue can be retrieved. In the case of poor sperm production, this technique may be performed through multiple entry points in the testicle in an effort to localize where sperm production may be occurring for subsequent open TESE. And then aspirated sperms are injected in to the eggs of patient through micromanipulator to achieve pregnancy.

PESA ,TESE and MESA are other methods to retrieve sperms in case of azoospermia
