Frequently Asked Questions

Testicular Sperm Extraction (TESE) is a fertility procedure used to directly retrieve sperm from the testicles in cases where there is no sperm present in the ejaculate. It is a more invasive technique than TESA and is commonly used in cases of non-obstructive azoospermia.

Fertility experts recommend the TESE procedure when there is a complete absence of sperm in the ejaculate due to non-obstructive azoospermia. This condition can develop due to various causes, including a lack of sperm production or testicular dysfunction. TESE is often performed in conjunction with ICSI to facilitate fertilisation in cases of non-obstructive azoospermia.

The TESE procedure involves surgically extracting small tissue samples from the testicles. These tissue samples are then carefully dissected and examined under a microscope to recognise and retrieve individual sperm. This procedure is typically conducted under general anaesthesia and may require a short hospital stay. The retrieved sperm is then used for ICSI or cryopreserved for future use.

As with any surgical procedure, TESE carries certain risks and potential complications. These can include bleeding, infection, pain, and swelling at the surgery site. In rare cases, damage to the testicular tissue or surrounding structures may occur. It is crucial to discuss these potential risks and complications with your fertility specialist before undergoing the TESE procedure.

The success rates of using sperm retrieved through TESE can vary and depend on various factors, including the underlying cause of male infertility and the overall health of the couple. On average, the success rates of using TESE-retrieved sperm in conjunction with ICSI range from 30% to 40%. It is essential to seek guidance from your fertility expert to understand your chances of success with TESE.
