Home »
TESE or PESA are sperm techniques that are part of IVF. These procedures involve obtaining sperm directly from the testicles in cases where they are not present in semen.
This Procedure Is Recommended When:
There isn’t enough sperm in the seminal sample
There is a blockage preventing sperm from properly exiting the male reproductive tract
TESE and Percutaneous Epididymal Sperm Aspiration (PESA) are procedures for obtaining sperm to be used with ICSI as part of an IVF cycle. TESE involves inserting a needle into the testis to extract sperm, while PESA requires passing a needle directly into the epididymal head of the testicle to aspirate sperm.
