PESA
Procedure Overview
PESA (Percutaneous Epididymal Sperm Aspiration) is a needle-based technique that retrieves sperm from the epididymis, the tube where sperm matures, mainly used for obstructive azoospermia where sperm production is normal but blocked.
Who Needs It
Recommended for men with obstructive azoospermia, where sperm production itself is normal but a blockage prevents sperm from reaching the ejaculate.
Preparation
Preparation includes an anatomical assessment, coordination with the partner's fertility cycle, and fasting if sedation is used.
Step-by-Step Procedure
Local Anesthesia
A local anesthetic is administered.
5 minNeedle Aspiration
A fine needle aspirates fluid directly from the epididymis.
10–15 minSample Examination
The sample is examined in the lab to confirm sperm presence.
15–30 minUse or Cryopreservation
Sperm is used fresh or cryopreserved for future use.
