What is MicroTESE?
MicroTESE represents one of the most advanced surgical sperm retrieval techniques currently available in reproductive medicine. A fertility surgeon uses a high-powered operating microscope to carefully examines the testicular tissue to identify small areas that may still produce sperm in men. Once extracted our embryologists can isolate viable sperm for Intracytoplasmic Sperm Injection (ICSI) during IVF.
MicroTESE maximises sperm retrieval while minimising damage to the testicular tissue, helping men with severely compromised sperm production
MicroTESE is usually performed in specialised fertility centres with expertise in male infertility.
Who is MicroTESE For?
MicroTESE is often recommended for men with
- non-obstructive azoospermia – the complete absence of sperm in the ejaculate which affects 10% of infertile men.
- chromosomal conditions such as Klinefelter syndrome,
- genetic abnormalities including Y‑chromosome microdeletion,
- a history of undescended testicles,
- prior chemotherapy or radiotherapy, or previous testicular injury such as torsion.
- After unsuccessful sperm retrieval attempts using TESA or conventional TESE.
What is Azoospermia?
Azoospermia is a condition in which no sperm are found in a man’s semen. Importantly, most men have no symptoms, so the condition is usually discovered only after a semen analysis is performed. The test should always be repeated to confirm the diagnosis. In some cases, the sample is centrifuged at high speed to detect very small numbers of sperm, a condition called Cryptozoospermia. If sperm are found, they can be frozen and later used for Intracytoplasmic Sperm Injection during In Vitro Fertilization.

Risks and Considerations
As with all surgical procedures, MicroTESE carries potential risks and limitations.
MicroTESE is generally a safe procedure, particularly when performed by an experienced microsurgeon. Because the operation is done under a high-powered operating microscope, the surgeon can precisely identify blood vessels and minimise damage to surrounding tissue. Complications are therefore uncommon. Possible risks include bleeding, infection, temporary swelling or discomfort, and in rare cases a small reduction in testicular function. When performed by an experienced specialist for men with non-obstructive azoospermia, the likelihood of significant complications is very low.
Importance of Specialist Consultation
Given the complexity of MicroTESE and the significance of the underlying conditions for which it is indicated, it is essential that patients receive a thorough pre-operative evaluation and individualised counselling from a fertility specialist with expertise in male infertility. This ensures that the procedure is appropriately indicated and that patients have realistic and evidence-based expectations regarding potential outcomes.
