Micro-TESE (Microscopic Testicular Sperm Extraction) is a surgical procedure that uses a high-power microscope to find and extract healthy sperm directly from inside the testis.
- It is done in an operating theatre, under magnification.
- The goal is to locate the tiny areas inside the testis that are most likely to contain sperm.
- The sperm retrieved can later be used to help a couple conceive a biological child.
This procedure is mainly recommended for men diagnosed with Non-Obstructive Azoospermia (NOA). In this condition, no sperm is found in the semen because the testis is not producing enough sperm.
Common reasons behind this condition include:
- Low natural sperm production
- Genetic reasons
- Hormonal imbalance
- Varicocele (swollen/enlarged veins in the scrotum)
- Radiation exposure
How Does the Micro-TESE Procedure Work?
A surgeon uses a high-power microscope to examine the seminiferous tubules — the thin, coiled tubes inside the testis where sperm is naturally produced.
Here is the step-by-step process:
- The surgeon opens the testis under magnification.
- Using the microscope, they identify the seminiferous tubules that look most likely to contain sperm.
- These specific tubules are carefully extracted.
- The extracted tissue is sent to a lab.
- In the lab, sperm is separated from the tissue sample.

What Happens to the Sperm After Extraction?
The sperm retrieved through Micro-TESE is not used for natural conception — it is used through assisted reproduction techniques.
- It can be used with IVF (In Vitro Fertilization).
- It can be used with ICSI (Intracytoplasmic Sperm Injection), where a single sperm is injected directly into an egg.
- Both routes aim to help the couple achieve a biological pregnancy.
Why Is Micro-TESE Considered a Better Option?
The biggest advantage of Micro-TESE is that it improves the chances of finding sperm while keeping damage to the testis to a minimum.
- The microscope allows precise targeting of the tubules most likely to have sperm.
- Because the surgeon can see clearly, less healthy tissue needs to be disturbed.
- This means lower risk to the patient compared to a blind extraction approach.
- It significantly increases the odds of successfully locating sperm in men with Non-Obstructive Azoospermia.

Frequently Asked Questions
No. Micro-TESE uses a high-power microscope to target specific sperm-producing tubules, unlike standard extraction methods that don't use this level of magnification.
Men diagnosed with Non-Obstructive Azoospermia, where sperm is not found in the semen due to low production, genetic causes, hormonal imbalance, varicocele, or radiation exposure.

The procedure is designed to minimize tissue damage. Because the surgeon can see clearly under the microscope, only the most relevant tissue is targeted, which lowers risk compared to a blind approach.
