Understanding Micro TESE / M-TESE Procedure

What is Micro TESE / M-TESE?

Microsurgical testicular sperm extraction (Micro TESE or M-TESE) is an advanced surgical technique used to retrieve sperm directly from the seminiferous tubules of the testicles. It is primarily indicated for men diagnosed with non-obstructive azoospermia (NOA)—a condition in which sperm production is so minimal that it is undetectable in semen.

Where is Micro TESE Indicated?

Micro TESE is most often recommended for men with:

• Non-obstructive azoospermia (NOA)
• Obstructive azoospermia (OA) where reconstruction is not possible or has failed
• As an option before assisted reproductive techniques like IVF/ICSI

In men with obstructive azoospermia, sperm retrieval can be done via various techniques such as:

• Percutaneous Epididymal Sperm Aspiration (PESA)
• Microsurgical Epididymal Sperm Aspiration (MESA)
• Open Fine-Needle Aspiration (OFNA)
• Single Open Testicular Biopsy

How Successful is Micro TESE?

Sperm retrieval success using micro TESE is reported in up to 63% of men. However, outcomes are significantly influenced by the presence and distribution of sperm in the testicles, which can be focal and challenging to locate in NOA cases. Microsurgical precision is essential in maximizing the chances of finding viable sperm.

How Long Does a TESE Procedure Take?

The time required for the procedure varies based on technique:

• Simple aspiration under local anesthesia: ~10 minutes
• Microsurgical sperm extraction for NOA: Can take several hours

Is the TESA/Micro TESE Procedure Painful?

Patients undergoing TESA or Micro TESE may experience mild discomfort, swelling, or pain post-procedure. These methods are considered minimally invasive and recovery is typically quick. PESA and TESA are suitable for men with both obstructive and non-obstructive oligozoospermia.
