Microscopic Testicular Sperm Extraction (Micro TESE)
Micro TESE is the most advanced microsurgical sperm retrieval technique for men with non-obstructive azoospermia, offering the best chance of finding usable sperm [web:6][web:7][web:10].
What is Micro TESE?
Micro TESE (Microscopic Testicular Sperm Extraction) is an advanced surgical procedure recommended for men with non-obstructive azoospermia - where sperm are absent in semen due to production problems rather than blockages [web:10].
During the procedure, a surgical microscope is used to accurately locate and remove only the testicular tissue most likely to contain sperm, thus minimizing damage and preserving healthy tissue [web:6][web:7][web:10]. This microsurgical approach has a precise and targeted methodology with minimal risk [web:10].
When is Micro TESE Recommended?
Micro TESE is the treatment of choice for:
- Non-obstructive azoospermia - problems with sperm production [web:10]
- Very low or zero sperm count [web:6]
- Failed previous sperm retrieval attempts (TESA, PESA)
- Testicular failure or dysfunction
- Sertoli cell-only syndrome
- Maturation arrest
- Genetic conditions affecting sperm production (e.g., Klinefelter syndrome)
Micro TESE provides the best chance at finding usable sperm in these challenging cases [web:7].
Micro TESE Procedure Steps
- Anesthesia: General or local anesthesia is administered [web:7]
- Surgical incision: A small incision is made in the scrotum to expose the testis
- Microscopic examination: A high-powered surgical microscope (up to 25x magnification) is used to identify tubules most likely to contain sperm [web:7]
- Selective tissue extraction: Only promising tissue is carefully removed, preserving maximum testicular tissue [web:7]
- Real-time laboratory analysis: Extracted tissue is immediately examined for sperm presence
- Cryopreservation: Found sperm are frozen for use in IVF/ICSI
- Closure: The incision is closed with absorbable sutures
The procedure can take 2-4 hours depending on the case complexity [web:6].
Advantages of Micro TESE
- Highest sperm retrieval rates for non-obstructive azoospermia (50-60%)
- Precise visualization minimizes testicular tissue damage [web:6]
- Preserves healthy tissue and testosterone production [web:10]
- Best option when other retrieval methods have failed [web:7]
- Lower complication rates compared to blind biopsies
- Sperm can be frozen for multiple IVF/ICSI cycles
- Provides hope for men with severe sperm production issues
Recovery and Aftercare
Recovery from Micro TESE typically takes 1-2 weeks. Post-procedure care includes:
- Rest for 48-72 hours after surgery
- Ice packs to reduce swelling
- Scrotal support garment for 1-2 weeks
- Pain medication as prescribed
- Avoid strenuous activity for 2-3 weeks
- Follow-up appointments to monitor healing
Most men recover well with minimal complications. The procedure has a very low complication rate, and recovery is usually efficient [web:7].
Success Rates and Expectations
Micro TESE offers the highest sperm retrieval rates for non-obstructive azoospermia:
- Overall sperm retrieval rate: 50-60%
- Success varies by underlying condition
- Higher success in cases with scattered sperm production
Even finding a small number of sperm can lead to successful pregnancy through ICSI. Your fertility specialist will discuss realistic expectations based on your specific diagnosis.
Why Micro TESE Over Other Methods?
- vs TESA: Micro TESE uses microscope for precise identification; TESA is blind needle aspiration
- vs Conventional TESE: Micro TESE removes less tissue with higher success rates
- For non-obstructive azoospermia: Micro TESE is the gold standard with best outcomes
- Tissue preservation: Minimizes damage to testicular tissue and hormone production

FAQs
How is Micro TESE different from regular TESE?
Micro TESE uses a high-powered surgical microscope to precisely identify and extract tissue most likely to contain sperm, while preserving healthy tissue. Regular TESE removes tissue blindly without microscopic guidance.
What are the chances of finding sperm with Micro TESE?
For non-obstructive azoospermia, Micro TESE has a sperm retrieval success rate of 50-60%, which is significantly higher than conventional methods. Success depends on the underlying cause of azoospermia.
Will Micro TESE affect my testosterone levels?
Micro TESE is designed to minimize tissue removal and preserve testosterone-producing cells. Most men maintain normal hormone levels after the procedure.
Can Micro TESE be repeated if unsuccessful?
Yes, Micro TESE can be repeated after adequate healing time (typically 6-12 months). However, success rates may be lower in repeat procedures.
When is Micro TESE performed in relation to IVF?
Micro TESE is usually performed before the IVF cycle, and retrieved sperm are cryopreserved. The frozen sperm are then thawed and used for ICSI when the female partner's eggs are retrieved.
