Percutaneous Epididymal Sperm Aspiration (PESA)

Percutaneous Epididymal Sperm Aspiration (PESA) is a minimally invasive procedure used to retrieve sperm directly from the epididymis in men with obstructive azoospermia. Although sperm are produced normally, blockages prevent them from reaching the semen. PESA provides viable sperm for use in IVF or ICSI treatments.

When is PESA Recommended?

Previous vasectomy (for men seeking fatherhood without reversal surgery)
Congenital absence of vas deferens (CAVD), often linked to cystic fibrosis
Blockages in the epididymis or vas deferens due to infections, trauma, or prior surgeries

Steps Involved in PESA

Local Anesthesia: The scrotal area is numbed for comfort.
Needle Aspiration: A fine needle is inserted into the epididymis to aspirate fluid containing sperm.
Sperm Processing: The retrieved sample is processed in the lab to isolate viable sperm for ICSI or for freezing.

Benefits of PESA

Simple, quick, and minimally invasive
Performed under local anesthesia as a day-care procedure
Provides sperm for immediate use or future IVF/ICSI cycles
Effective for men with obstructive azoospermia

Possible Risks

Mild pain or swelling at the needle site
Minimal risk of bleeding or infection
Occasional need for repeat aspiration if sperm yield is low
