Empowering biological fatherhood through state-of-the-art micro-surgical techniques (PESA, TESA, MESA, Micro-TESE) — even when sperm count is zero in the ejaculate.
Equipped with ultra-high magnification Carl Zeiss operating microscopes.
Retrieval Success in Obstructive Cases
For men diagnosed with Azoospermia (zero sperm in the ejaculate), surgical sperm retrieval offers a highly reliable opportunity to father biological children. By retrieving sperm directly from the epididymis or testes, our reproductive andrologists combine healthy gametes with ICSI (Intracytoplasmic Sperm Injection) for optimal fertilization.
Effective for both Obstructive (blockage) and Non-Obstructive (production) conditions.
Avoid complex re-anastomosis surgery with direct, swift sperm harvesting.
Enables couples to use the husband's own genetic material rather than donor sperm.
Day-care procedures with local/mild anesthesia and minimal post-op downtime.
Each case of male factor infertility is unique. Our expert andrology surgeons choose the most tailored technique depending on whether the condition is obstructive or non-obstructive.
PESA
A gentle needle aspiration technique performed directly on the epididymis under local anesthesia without skin incisions.
TESA / TESE
Direct needle aspiration (TESA) or tiny micro-biopsy (TESE) from the testicular tissue when epididymal sperm is insufficient.
MESA
An open microsurgical approach using an operating microscope to isolate dilated epididymal tubules for maximum sperm harvest.
Micro-TESE
High-magnification (20x-25x) optical search for active seminiferous tubules, maximizing retrieval while preserving tissue.
Understand the differences to make an informed clinical decision alongside our andrologists.
| Feature | PESA | TESA / TESE | MESA | Micro-TESE |
|---|---|---|---|---|
| Target Location | Epididymis | Testes (Seminiferous Tubules) | Epididymal Tubules | Specific Active Testicular Tubules |
| Primary Indication | Obstructive Azoospermia | Obstructive / Mild Non-Obstructive | Congenital Vas Agenesis / Obstruction | Severe Non-Obstructive Azoospermia |
| Incision Type | Needle Puncture (No incision) | Needle or Micro-punch incision | Small Open Microsurgical | Open Microsurgical Exploration |
| Microscope Needed | No | Lab Microscope Only | Operating Microscope | High-Power 25x Operating Microscope |
| Freezing Potential | Moderate | Good | Excellent (Multiple Vials) | Good for ICSI |
Even with severe male factor infertility, revolutionary surgical retrieval technologies make your dream of holding your biological baby possible. Talk confidentially with our leading andrologists today.
