Testicular Sperm Aspiration (TESA)

Overview

Testicular Sperm Aspiration, commonly known as TESA, is a minimally invasive procedure to retrieve sperm directly from the testes when natural ejaculation does not provide viable sperm. This procedure is often recommended for men with non-obstructive azoospermia or low sperm count, giving hope to couples struggling with male infertility.

Facing infertility can be emotionally taxing, but TESA provides a safe and effective solution to retrieve sperm for use in assisted reproductive techniques like ICSI, offering couples a chance to achieve their dream of parenthood.

What is TESA?

TESA is a surgical sperm retrieval technique in which a small needle is inserted into the testicle to aspirate sperm-containing tissue. Unlike more invasive procedures, TESA is quick, minimally invasive, and usually done under local anesthesia.

Other related sperm retrieval techniques include:

• PESA (Percutaneous Epididymal Sperm Aspiration) – sperm collected from the epididymis
• Micro-TESE (Microsurgical Testicular Sperm Extraction) – highly precise method for men with severe testicular failure

Why is TESA Done?

TESA is performed in cases such as:

• Non-obstructive azoospermia (low or no sperm in ejaculate due to testicular failure)
• Obstructive azoospermia where epididymal retrieval fails
• Men who have undergone vasectomy, trauma, or genital surgery
• Preparation for ICSI (Intracytoplasmic Sperm Injection)
• Couples seeking fertility solutions when conventional sperm retrieval is not possible

Preparation for TESA

• Complete medical history review and physical examination
• Blood tests and hormonal evaluation
• Abstain from ejaculation for 2–3 days before the procedure
• Avoid alcohol, smoking, or medications affecting blood clotting
• Counseling and emotional support to reduce anxiety about the procedure

Process of TESA

1. Anesthesia: Local anesthesia is administered to minimize discomfort.
2. Needle Aspiration: A fine needle is inserted directly into the testicular tissue to retrieve sperm.
3. Sperm Assessment: The aspirated sample is examined under a microscope to check sperm quality and viability.
4. Sperm Processing: Viable sperm is washed, prepared, and either used immediately for ICSI or cryopreserved for future use.
5. Duration: The procedure typically takes 15–30 minutes, with minimal downtime.

Results / What to Expect

• Immediate availability of viable sperm for fertilization
• Minimal post-procedure discomfort: mild swelling, bruising, or tenderness
• Short recovery time; most men can return home on the same day
• Enables couples to proceed with ICSI or IVF despite male infertility challenges

Risks / Considerations

• Mild pain, swelling, or bruising at the site
• Rare infection or hematoma
• Slight risk of testicular tissue damage, minimized with skilled surgeons
• Low complication rates; procedure is generally safe and well-tolerated

When Should You See a Fertility Specialist?

• No sperm detected in semen analysis (azoospermia)
• History of vasectomy, genital surgery, or trauma
• Difficulty conceiving despite regular unprotected intercourse
• Erectile or ejaculatory issues affecting sperm retrieval

Common Signs You May Need Fertility Testing

• Failure to conceive after 12 months of trying
• Abnormal semen analysis (low sperm count, poor motility, or azoospermia)
• Pain, swelling, or obstruction in the reproductive tract
• Prior genital trauma, infection, or congenital issues affecting sperm delivery

Frequently Asked Questions (FAQs)

1. Is TESA painful? No. Local anesthesia ensures minimal discomfort. Mild swelling or tenderness may occur for a few days.
2. Can TESA sperm be used immediately? Yes, TESA sperm can be used fresh for ICSI or frozen for future fertility treatments.
3. How long does the procedure take? Typically 15–30 minutes with same-day discharge.
4. Will TESA affect testicular function? No. TESA is minimally invasive and generally does not impact hormone production or testicular health.
5. What is the success rate? Success depends on sperm quality and female partner fertility, but TESA is effective for providing sperm for ICSI.
