Frequently Asked Questions

The Percutaneous Epididymal Sperm Aspiration (PESA) procedure helps retrieve sperm from the epididymis, a structure present at the back of the testicles, in cases where a blockage in the reproductive tract prevents the release of sperm during ejaculation.

PESA is recommended when there is a blockage in the reproductive tract that prevents the release of sperm during ejaculation. Various conditions can cause this prevention, including previous surgeries, congenital abnormalities, or infections. PESA is often performed in conjunction with ICSI to facilitate fertilisation in cases of obstructive azoospermia.

The PESA procedure involves the insertion of a fine needle directly into the epididymis to aspirate sperm. This procedure is typically conducted under local anaesthesia and can be done on an outpatient basis. The fertility experts use these retrieved sperm or ICSI or cryopreserved for future use. PESA is a relatively quick and straightforward procedure that can effectively treat couples with obstructive azoospermia.

As with any medical procedure, PESA 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 epididymis or surrounding structures may occur. It is essential to discuss the potential risks and complications with your fertility specialist before undergoing the PESA procedure.

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