PESA: Percutaneous Epididymal Sperm Aspiration

What is PESA? It is a technique used to collect sperm directly from the epididymis (a tube that is connected to your testicle that helps store and transport the sperm).

When do you do PESA? For men who don’t have sperm in their semen (azoospermia) or have difficulty in collecting semen, PESA is performed. Commonly used for Obstructive Azoospermia – when something is stopping sperm from coming out.

(True Azoospermia is when there are no sperm being produced. This requires donor sperm)

What is the PESA Procedure?

  1. Local Anesthesia is used to numb the testicle. A thin needle is inserted in the epididymis and the sperm is aspirated (sucked out).
  2. The collected sperm is then given for ICSI.
