Frequently Asked Questions

Testicular Sperm Aspiration (TESA) is a fertility procedure used to retrieve sperm from the testicles in cases where there is no sperm present in the ejaculate. Fertility experts perform this minimally invasive procedure under local anaesthesia, and it is a first-line approach in cases of male infertility.

Testicular Sperm Aspiration (TESA) is recommended when there is a complete absence of sperm in the ejaculate, a condition known as azoospermia. Various factors can result in this condition, including blockages in the reproductive pathway or a lack of sperm production. TESA is also favourable in cases where previous attempts at sperm retrieval, such as PESA or TESE, have been unsuccessful.

The TESA procedure involves the use of a fine needle to aspirate sperm directly from the testicles. This method is generally performed under local anaesthesia to minimise discomfort. After retrieving the sperm, fertility experts can use it for ICSI or cryopreserve it for future use. TESA is a relatively quick and straightforward procedure performed on an outpatient basis.

As with any medical procedure, TESA carries certain risks and potential complications. These can include bleeding, infection, pain, and swelling at the site of the needle aspiration. In rare cases, damage to the testicular tissue or surrounding structures may occur. Therefore, it is necessary to discuss the potential complications with your fertility specialist before undergoing the TESA procedure.

The success rates of using sperm retrieved through TESA can vary depending on various factors, including the underlying reason for male infertility and the couple’s overall health. On average, the success rates of using TESA-retrieved sperm in conjunction with ICSI range from 30% to 40%. It is essential to counsel your fertility specialist to understand your chances of success with TESA.
