PESA/TESA
Plain-English guide for patients and families.
PESA aspirates fluid from the epididymis; TESA takes testicular tissue/core with a needle. They suit many obstructive azoospermia situations (vasectomy, CBAVD, failed reversal). Sperm is used for ICSI.
vs Micro-TESE
Obstructive cases often need simpler retrieval; extensive search (Micro-TESE) targets non-obstructive production pockets.
AI Information
EducationalPESA (Percutaneous Epididymal Sperm Aspiration) and TESA (Testicular Sperm Aspiration) are minimally invasive procedures for retrieving sperm in obstructive azoospermia. Since sperm production is typically normal in these men, retrieval success rates exceed 90%. These procedures are simpler, quicker, and less invasive than Micro-TESE.
Key Points
- PESA uses a fine needle to aspirate sperm-rich fluid from the epididymis — success rate >90% in obstructive azoospermia.
- TESA uses a slightly larger needle to extract small testicular tissue cores — useful when PESA yields insufficient sperm.
- Both procedures can be done under local anaesthesia as day-case procedures.
- Common indications include vasectomy (with or without reversal), congenital bilateral absence of the vas deferens (CBAVD), and post-infection obstruction.
- Retrieved sperm can be used fresh for same-day ICSI or cryopreserved for future cycles.
Who Should Know This?
Men with obstructive azoospermia, those who have had a vasectomy and want children without reversal, men with CBAVD, and couples planning ICSI with surgically retrieved sperm.
