Epididymal Sperm Aspiration

What is Epididymal Sperm Aspiration?

Epididymal sperm aspiration is a procedure used to retrieve sperm directly from the epididymis in men with obstructive azoospermia. It allows biological fatherhood through assisted reproductive techniques such as IVF or ICSI.

Who is a Suitable Candidate?

• Men with obstructive azoospermia
• Men with prior vasectomy
• Congenital absence of vas deferens
• Blockage in the reproductive tract

Types of Epididymal Sperm Retrieval

• PESA (Percutaneous Epididymal Sperm Aspiration) – needle-based technique
• MESA (Microsurgical Epididymal Sperm Aspiration) – performed under microscope for precise sperm retrieval

How the Procedure is Performed

• Performed under local or general anesthesia
• A fine needle or microsurgical technique is used to retrieve sperm
• Sperm is immediately processed for fertility treatment or cryopreservation

The procedure usually takes 20–45 minutes.

Expected Benefits

• Direct sperm retrieval in obstructive infertility
• Avoids the need for donor sperm
• Enables IVF or ICSI treatment

Recovery

• Same-day discharge
• Mild scrotal discomfort or swelling
• Return to routine activities within a few days
