Micro-TESE
Procedure Overview
Micro-TESE (Microsurgical Testicular Sperm Extraction) is an advanced technique that uses a high-magnification operating microscope to identify and retrieve sperm-producing areas within the testicle, offering the best chance of finding sperm in men with non-obstructive azoospermia.
By precisely targeting the areas most likely to contain sperm, Micro-TESE removes less tissue than older, blind extraction techniques while achieving higher success rates.
Who Needs It
Recommended for men with non-obstructive azoospermia, where sperm production itself is severely impaired rather than simply blocked.
Preparation
Preparation includes hormone testing, genetic counseling where indicated, and coordination with the partner's IVF/ICSI treatment cycle.
Step-by-Step Procedure
Anesthesia
General or spinal anesthesia is administered.
15–20 minTesticular Exposure
The testicle is carefully opened to allow microscopic examination.
20–30 minMicroscopic Examination
The operating microscope is used to identify the tubules most likely to contain sperm.
60–120 minTissue Retrieval
Small samples from identified areas are retrieved and examined by the embryology lab.
ConcurrentClosure
The testicle and surgical site are carefully closed.
20 minBenefits
- ✓Highest sperm retrieval success among techniques for non-obstructive azoospermia
- ✓Removes less tissue than older, non-microsurgical techniques
- ✓Enables biological fatherhood in many previously untreatable cases
Recovery Timeline
This is typically a day-care or overnight-stay procedure, with a return to light activity within a week and strenuous activity avoided for 2–3 weeks.
