Percutaneous Epididymal Sperm Aspiration (PESA)

Overview

Percutaneous Epididymal Sperm Aspiration, commonly known as PESA, is a minimally invasive procedure to retrieve sperm directly from the epididymis when natural ejaculation does not provide viable sperm. This procedure is especially helpful for men with obstructive azoospermia, where a blockage prevents sperm from being present in the ejaculate.

Experiencing infertility can be emotionally challenging for men and couples. PESA offers hope, providing sperm for use in assisted reproductive techniques like ICSI, helping couples realize their dream of parenthood.

What is PESA?

PESA is a surgical sperm retrieval technique that involves using a fine needle to aspirate sperm directly from the epididymis, a small coiled tube near the testis where sperm mature. Unlike more invasive surgical procedures, PESA is quick, minimally invasive, and can be done under local anesthesia.

Other related sperm retrieval procedures include:

• TESA (Testicular Sperm Aspiration) – direct retrieval from testicular tissue
• Micro-TESE (Microsurgical Testicular Sperm Extraction) – highly precise surgical sperm extraction for men with severe testicular failure

Why is PESA Done?

PESA is performed in cases of:

• Obstructive azoospermia (blockage in the vas deferens or epididymis)
• Failed sperm retrieval through ejaculation
• Men with congenital absence of vas deferens, vasectomy, or scarring
• Preparation for ICSI (Intracytoplasmic Sperm Injection) in assisted reproduction
• Men who want a minimally invasive sperm retrieval option

Preparation for PESA

• Medical history review and physical examination
• Blood tests and fertility evaluation for both partners
• Abstain from ejaculation for 2–3 days to optimize sperm quality
• Avoid alcohol, smoking, or medications affecting clotting
• Emotional readiness and counseling to reduce stress and anxiety

Process of PESA

1. Local or general anesthesia is administered to ensure comfort.
2. A fine needle is inserted into the epididymis to aspirate sperm.
3. The aspirated fluid is examined under a microscope to check for sperm viability.
4. Viable sperm is processed, washed, and preserved for use in ICSI or IVF.
5. The procedure is typically completed within 15–30 minutes, with minimal discomfort.

Results / What to Expect

• Immediate availability of viable sperm for assisted reproductive procedures
• Short recovery time, usually same-day discharge
• Minimal post-procedure discomfort, mild swelling, or bruising
• Enables couples with male infertility challenges to proceed with ICSI successfully

Risks / Considerations

• Mild pain, swelling, or bruising at the puncture site
• Rare infection or hematoma
• Minor risk of damage to the epididymis or testis, minimized with experienced surgeons
• Typically safe with low complication rates

When Should You See a Fertility Specialist?

• No sperm detected in semen analysis (azoospermia)
• History of vasectomy, genital surgery, or infection
• Difficulty conceiving despite regular, unprotected intercourse
• Persistent erectile or ejaculatory issues

Common Signs You May Need Fertility Testing

• Partner unable to conceive after 12 months of trying
• Abnormal semen analysis (low sperm count or no sperm)
• Pain, swelling, or obstruction in the reproductive tract
• Prior genital trauma or congenital absence of vas deferens

Your Fertility Journey at Milann (Step-by-Step)

1. Initial Consultation: Discuss infertility concerns, medical history, and previous treatments
2. Assessment: Semen analysis, hormonal evaluation, imaging studies of testes and epididymis
3. Procedure Planning: Determine suitability for PESA or alternative sperm retrieval methods
4. PESA Procedure: Minimal anesthesia, sperm retrieval, immediate assessment
5. ICSI/IVF Integration: Retrieved sperm is used for fertilization and embryo transfer
6. Follow-Up: Monitor recovery, manage complications, and optimize fertility outcomes

Frequently Asked Questions (FAQs)

1. Is PESA painful? Most men experience minimal discomfort due to local anesthesia. Mild swelling or tenderness may last a few days.
2. Can sperm retrieved via PESA be used immediately? Yes, PESA sperm can be used fresh for ICSI or frozen for later use.
3. How long does the procedure take? Typically, 15–30 minutes with same-day discharge.
4. Does PESA affect testicular function? No. PESA is minimally invasive and rarely affects hormone production or testicular health.
5. What is the success rate? Success depends on sperm quality and female partner’s fertility, but PESA is highly effective for providing sperm for ICSI.
