What is Micro-TESE?
💡 Micro-TESE is microsurgical testicular sperm extraction performed under an operating microscope at 6–25x magnification. It identifies dilated seminiferous tubules with active spermatogenesis in non-obstructive azoospermia. Sperm retrieval rate: 30–60%. Retrieved sperm are used exclusively with ICSI.
Micro-TESE (microsurgical testicular sperm extraction) is the gold-standard surgical procedure for retrieving sperm from testicular tissue in men with non-obstructive azoospermia. It uses operating microscope magnification to identify seminiferous tubules with active sperm production.
🇮🇳 India Context: Micro-TESE is widely assessed and treated across major Indian fertility centres including Chennai, Mumbai, Bangalore, Delhi, and Hyderabad.
What are the key characteristics of Micro-TESE?
- Indicated for non-obstructive azoospermia (NOA) — where sperm production is impaired but focal areas may remain active
- Performed under operating microscope at 6–25x magnification — identifies dilated, pale tubules with active spermatogenesis
- Sperm retrieval rate: 30–60% in NOA — varies by diagnosis (Klinefelter: 30%; maturation arrest: 40–60%; hypospermatogenesis: 60–80%)
- Higher yield than conventional TESE — microscope identifies productive areas, reducing testicular damage
- Performed under general anaesthesia — day-case surgery, 2–3 hours
- Retrieved sperm used exclusively with ICSI — quantities too small for conventional IVF fertilisation
- Unused sperm cryopreserved for future ICSI cycles — avoiding repeat surgery
- Requires reproductive urologist and coordinated IVF embryology team simultaneously
What does Micro-TESE involve?
Why does Micro-TESE matter in fertility?
Micro-TESE provides the only path to biological fatherhood for 30–60% of NOA men using their own sperm. Without it, these men require donor sperm or remain childless. Compared to conventional TESE, micro-TESE achieves significantly higher retrieval rates while preserving more functional testicular tissue — reducing post-operative testosterone deficiency risk. Testosterone levels should be rechecked 3–6 months post-procedure. In India, micro-TESE is available at specialist andrology and IVF centres in major cities; costs range from ₹50,000–₹1,50,000.

FAQs about Micro-TESE
Who needs Micro-TESE?
Micro-TESE is indicated for non-obstructive azoospermia (NOA) — where sperm production is severely impaired. Causes include Klinefelter syndrome, maturation arrest, Sertoli-cell-only syndrome, and hypospermatogenesis. It is not needed for obstructive azoospermia (use PESA or MESA).
What is the success rate of Micro-TESE?
Sperm retrieval rate in Micro-TESE is 30–60% overall in non-obstructive azoospermia. Rates vary by diagnosis: Klinefelter syndrome 30%, maturation arrest 40–60%, hypospermatogenesis 60–80%. Results cannot be predicted before surgery.
Is Micro-TESE painful?
Micro-TESE is performed under general anaesthesia — no pain during surgery. Post-operative scrotal discomfort, bruising, and swelling are common for 3–7 days. Most men return to light activity within 1 week. Paracetamol and scrotal support manage post-op discomfort.
What is the difference between TESE and Micro-TESE?
Conventional TESE is a blind biopsy — tissue taken without microscopic guidance. Micro-TESE uses operating microscope magnification to identify dilated, sperm-producing tubules specifically. Micro-TESE achieves higher retrieval rates and causes less testicular damage than conventional TESE.
How much does Micro-TESE cost in India?
Micro-TESE costs ₹50,000–₹1,50,000 in India depending on the centre and surgeon. This does not include the concurrent ICSI cycle cost (₹1,00,000–₹2,50,000). Specialist andrology centres in major cities offer the procedure.
Can sperm found in Micro-TESE be frozen?
Yes. Sperm retrieved during Micro-TESE are routinely cryopreserved in multiple vials after completing the same-day ICSI requirement. Frozen testicular sperm can be used for future ICSI cycles — avoiding repeat surgery.
