Micro-TESE in Delhi
Microsurgical Sperm Retrieval for Azoospermia — Pravi IVF
Even with a zero sperm count, biological fatherhood may still be possible. Pravi IVF's expert urologists use high-powered operating microscopes to precisely locate and extract viable sperm directly from the testis — giving you the highest possible chance of success.
What is Micro-TESE?
Micro-TESE — short for Microsurgical Testicular Sperm Extraction — is the most advanced and effective surgical technique available for retrieving sperm in men diagnosed with non-obstructive azoospermia (NOA). Unlike conventional sperm retrieval methods, Micro-TESE uses a high-powered surgical microscope to magnify the testicular tissue up to 25 times, enabling the urologist to visually identify the specific tubules most likely to contain active sperm production.
Developed and refined over the past two decades, Micro-TESE is now the internationally recognised gold standard for NOA management. At Pravi IVF, Lajpat Nagar, Delhi, our urology team performs this procedure with exceptional precision — preserving as much healthy testicular tissue as possible while maximising the chance of finding viable sperm for use in ICSI-IVF.
Who Should Consider Micro-TESE?
Micro-TESE is specifically indicated for men where conventional sperm retrieval has failed or is unlikely to succeed. Our specialists will review your full diagnostic history to confirm candidacy, particularly for those facing:
Micro-TESE vs. Conventional TESA
Conventional TESA (Needle Extraction)
A blind needle biopsy that extracts tissue from random areas of the testis. Since sperm production is focal, it yields lower retrieval rates (20-30%) and risks damaging blood vessels and healthy hormone-producing Leydig cells.
Micro-TESE (Microsurgical Extraction)
An advanced microsurgical procedure using an operating microscope magnified up to 25x. The urologist visually identifies and targets only the active, healthy tubules producing sperm, achieving 40-60% retrieval with minimal tissue loss.
The Micro-TESE Process at Pravi IVF
Pre-Surgical Evaluation
A thorough assessment including semen analysis, hormonal profile (FSH, LH, testosterone), genetic karyotyping, and scrotal ultrasound to confirm the diagnosis of non-obstructive azoospermia and plan surgery.
Anaesthesia & Setup
Micro-TESE is performed under general anaesthesia in a fully equipped operating theatre. The procedure typically takes 2–3 hours and is performed on an outpatient or day-care basis.
Microsurgical Exploration
Using a high-powered operating microscope (×15–25 magnification), the surgeon identifies dilated, opaque tubules in the testis that are most likely to contain active spermatogenesis.
Targeted Sperm Extraction
Small tissue samples from only the most promising tubules are excised — preserving maximum healthy testicular tissue and minimising damage to blood supply and hormone-producing Leydig cells.
Embryology Lab Processing
Our embryologists immediately process each sample under the microscope to identify and isolate viable, motile sperm for use in ICSI (Intracytoplasmic Sperm Injection).
ICSI & IVF Cycle
Retrieved sperm are used fresh or cryopreserved for a future ICSI-IVF cycle with the partner's eggs, offering the best possible chance of fertilisation and a healthy pregnancy.
Why Micro-TESE is a Life-Changing Procedure
The Science of Focal Spermatogenesis
In men with NOA, sperm production doesn't simply stop everywhere — instead, it may persist in isolated, microscopic pockets within the testis known as areas of focal spermatogenesis. These active tubules are indistinguishable from inactive ones to the naked eye. The operating microscope changes everything. Dilated, opaque-white tubules indicate active sperm production, while flat, translucent tubules do not. This visual intelligence is what gives Micro-TESE its decisive edge over blind-needle TESA techniques.
Preserving Testicular Function Long-Term
A major concern with any testicular surgery is the impact on testosterone production by Leydig cells and the long-term health of remaining testicular tissue. Micro-TESE's targeted, microscope-guided approach removes the smallest amount of tissue necessary, causing significantly less damage than conventional TESE or multiple-needle TESA. Studies show that testosterone levels in men after Micro-TESE recover faster and with less overall decline compared to conventional techniques.
Klinefelter Syndrome & Micro-TESE
Men with Klinefelter Syndrome (47,XXY) — the most common genetic cause of NOA — were previously told fatherhood was impossible. Micro-TESE has transformed this reality. Published data shows sperm retrieval rates of 30–70% in Klinefelter patients undergoing Micro-TESE, depending on hormonal status and age at the time of surgery. Our team also assesses the role of prior prior hormonal optimisation (testosterone normalisation) to further improve retrieval outcomes.

Frequently Asked Questions About Micro-TESE
QWhat is Micro-TESE and who needs it?
Micro-TESE (Microsurgical Testicular Sperm Extraction) is the gold-standard surgical procedure for men with non-obstructive azoospermia — a condition where no sperm are present in the ejaculate due to a production failure within the testes. Using an operating microscope, the surgeon identifies and extracts sperm directly from the most productive tubules of the testis.
QWhat are the success rates of Micro-TESE?
At experienced centres like Pravi IVF, Micro-TESE achieves sperm retrieval rates of 40–60% in men with NOA — significantly higher than conventional TESA (20–30%). Success varies with the underlying diagnosis; certain conditions like hypospermatogenesis yield higher rates than Sertoli Cell Only Syndrome.
QIs the procedure painful? What is the recovery like?
Micro-TESE is performed under general anaesthesia, so you feel nothing during the surgery. Post-operatively, mild scrotal discomfort and swelling are normal for 3–5 days. Most men return to desk work within a week. Strenuous activity is restricted for 3–4 weeks.
QCan sperm be frozen after Micro-TESE?
Yes. Any sperm retrieved that are not used immediately for a fresh ICSI cycle are cryopreserved for future use. This means the surgery doesn't need to be repeated if additional IVF cycles are required.
QHow is Micro-TESE combined with IVF for my partner?
Micro-TESE is coordinated with your partner's IVF ovarian stimulation cycle. Retrieved sperm are used in ICSI, where a single sperm is injected directly into each mature egg. The resulting embryos are cultured and the healthiest are transferred to the uterus.
