TESA & Micro TESE in Chennai

Yes. Micro TESE is specifically designed for non-obstructive azoospermia and has a sperm retrieval rate of approximately 40 to 60 percent in published studies. The operating microscope allows identification of the rare tubules that may still contain active sperm production, even when overall testicular function is severely impaired.

TESA is a needle-based aspiration best suited for obstructive azoospermia, where sperm production is normal but a blockage prevents delivery. Micro TESE is a microsurgical approach used when the testis itself produces very limited sperm (non-obstructive azoospermia). Your hormone levels, genetic tests, and clinical history guide the decision.

Absolutely. We routinely coordinate TESA or Micro TESE with the egg retrieval so freshly obtained sperm can be used for ICSI on the same day. This avoids the need to freeze and thaw sperm, which can sometimes reduce viability.

TESA is performed under local anaesthesia and most patients describe mild discomfort similar to a blood draw. You can typically return to desk-based work the next day and resume all normal activities within two to three days. Mild swelling or tenderness is managed with standard pain relief.

Yes. When vasectomy reversal does not restore sperm to the ejaculate, TESA offers an effective way to retrieve sperm directly from the testis. Because the underlying sperm production is usually normal after vasectomy, TESA success rates in this scenario are very high.

While uncommon with proper patient selection, it is possible. If no sperm are found, the tissue samples may be further processed and examined over 24 to 48 hours. We also discuss alternative paths forward, including donor sperm or additional investigations, with full sensitivity and support.

Yes. Sperm retrieved through TESA or Micro TESE can be cryopreserved using advanced vitrification techniques. This is especially useful if your partner is not yet ready for ovarian stimulation or if you wish to store sperm as a backup for future cycles.

We recommend a karyotype analysis, Y-chromosome microdeletion testing, and cystic fibrosis carrier screening (especially if congenital absence of vas deferens is suspected). These tests help predict the likelihood of sperm retrieval and identify any genetic factors that could affect future offspring.

Sperm retrieved through TESA can be used for ICSI on the same day as the retrieval, which is the preferred approach when timing is coordinated with your partner's egg collection. Using fresh sperm typically offers the best viability, though frozen sperm from a prior TESA procedure can also be thawed and used successfully in a later IVF cycle. Dr. Rukkayal routinely plans same-day coordination between retrieval and fertilisation to maximise outcomes.

Recovery after Micro TESE is generally straightforward, though it involves a slightly longer healing period than TESA since it is performed under general anaesthesia with a small testicular incision. Most men can return to desk-based work within three to five days and resume normal physical activity within one to two weeks. Post-operative care includes ice application, scrotal support, and mild pain relief. Dr. Rukkayal provides detailed recovery instructions and schedules a follow-up to ensure healing is progressing well.
