What is PESA?
Percutaneous Epididymal Sperm Aspiration (PESA) is a minimally invasive procedure used to retrieve sperm directly from the epididymis using a fine needle. It is commonly used for men diagnosed with obstructive azoospermia, where sperm production is normal, but a blockage prevents sperm from appearing in the semen. The retrieved sperm are typically used for ICSI (Intracytoplasmic Sperm Injection) as part of an IVF (In Vitro Fertilization) cycle.
When is PESA Recommended?
PESA is generally recommended in the following situations:
- Previous Vasectomy: For men who wish to father children without undergoing vasectomy reversal.
- Congenital Absence of the Vas Deferens (CAVD): Often seen in patients with Cystic Fibrosis.
- Obstructions in the Reproductive Tract: Caused by infections, trauma, or previous surgeries leading to blocked epididymis or vas deferens.
Steps Involved in PESA
- Local Anesthesia: A numbing agent is applied to minimize discomfort.
- Needle Aspiration: A fine needle is carefully inserted through the scrotal skin into the epididymis to aspirate fluid containing sperm.
- Sperm Analysis & Processing: The retrieved sample is examined under a microscope, processed, and either used for ICSI or cryopreserved for future use.
