Overview
Microsurgical Testicular Sperm Extraction, or Micro-TESE, is a specialized surgical procedure to retrieve sperm directly from the testicles in men who do not have sperm in their ejaculate due to non-obstructive azoospermia. This condition occurs when the testicles are unable to produce enough sperm naturally, often due to genetic, hormonal, or developmental issues.
Facing male infertility can be emotionally challenging, but Micro-TESE provides hope for men who want to become fathers, by allowing highly skilled surgeons to locate and extract viable sperm for use in advanced fertility treatments like ICSI (Intracytoplasmic Sperm Injection).
What is Micro-TESE?
Micro-TESE is a microsurgical sperm retrieval technique where a urologist examines the testicular tissue under a high-powered operating microscope to find areas producing sperm. This approach maximizes sperm recovery while minimizing tissue damage, making it the preferred method for men with very low or no sperm production in ejaculate.
Unlike TESA or PESA, which target the epididymis or testicular tissue blindly, Micro-TESE uses magnification and precision to identify microscopic sperm pockets.
Why is Micro-TESE Done?
Micro-TESE is recommended for men with:
- Non-obstructive azoospermia (testicular failure)
- Previous failed sperm retrieval attempts using TESA or PESA
- Genetic conditions like Klinefelter syndrome
- Hormonal or developmental issues affecting sperm production
- Desire to use ICSI for assisted reproduction when ejaculated sperm are unavailable
Preparation for Micro-TESE
- Complete medical evaluation, including semen analysis, hormonal tests, and genetic screening
- Abstain from ejaculation for 2–3 days prior to the procedure
- Avoid alcohol, smoking, and medications that affect clotting
- Emotional counseling to discuss expectations and potential outcomes
- Follow routine pre-operative instructions, including fasting if general anesthesia is used
Process of Micro-TESE
- Anesthesia: Usually performed under general or local anesthesia for comfort.
- Testicular Exposure: A small incision is made in the scrotum to expose the testicular tissue.
- Microsurgical Exploration: Using an operating microscope, the surgeon carefully examines the testis to locate sperm-producing regions.
- Sperm Extraction: Tiny amounts of tissue containing sperm are selectively removed.
- Sperm Processing: Extracted tissue is processed in the lab to identify and isolate viable sperm.
- Closure: The incision is sutured with minimal scarring; usually absorbable sutures are used.
- Duration: Procedure generally takes 1–3 hours, depending on complexity.
Results / What to Expect
- High-quality sperm suitable for ICSI or IVF
- Minimal post-operative discomfort: mild swelling, bruising, or tenderness
- Recovery time is generally a few days to a week
- Micro-TESE significantly increases chances of successful sperm retrieval in men with non-obstructive azoospermia
- Retrieved sperm can be used fresh or cryopreserved for future fertility treatments
Risks / Considerations
- Mild pain, swelling, or bruising at the surgical site
- Rare infection or hematoma formation
- Slight risk of testicular tissue damage, though minimized by microsurgical precision
- Temporary discomfort during healing
- Low complication rates with experienced surgeons
When Should You See a Fertility Specialist?
- No sperm detected in multiple semen analyses (azoospermia)
- History of genetic, hormonal, or testicular disorders
- Difficulty conceiving despite regular unprotected intercourse
- Previous unsuccessful attempts at sperm retrieval
Common Signs You May Need Fertility Testing
- Azoospermia or very low sperm count
- History of testicular trauma, infection, or surgery
- Hormonal imbalances affecting fertility
- Family history of genetic disorders affecting testicular function

Frequently Asked Questions (FAQs)
- Is Micro-TESE painful? No. Anesthesia ensures the procedure is pain-free. Mild swelling or tenderness is expected during recovery.
- How long does Micro-TESE take? Typically 1–3 hours, depending on testicular tissue and sperm production.
- Will Micro-TESE affect testosterone levels or testicular function? No. Microsurgical precision preserves healthy tissue and generally does not impact hormone production.
- Can Micro-TESE sperm be frozen? Yes, viable sperm can be cryopreserved for future use in ICSI cycles.
- What is the success rate? Micro-TESE provides the highest success rate for sperm retrieval in men with non-obstructive azoospermia, often exceeding 50% depending on individual testicular function.
