Difference between TESA, TESE, MESA, PESA?

When it comes to male infertility, there are several treatment options available. Some of these options involve surgical procedures to retrieve sperm. In this blog, we will discuss the differences between four such procedures: TESA, TESE, MESA, and PESA. These procedures are performed at the New World Fertility Centre in Delhi by highly skilled fertility specialists.

What is TESA (Testicular Sperm Aspiration)?

TESA stands for Testicular Sperm Aspiration. It is a procedure in which a fine needle is used to aspirate sperm directly from the testicles. This procedure is typically performed when there is no sperm in the ejaculate (azoospermia) or when the sperm count is very low (oligospermia).

What is TESE (Testicular Sperm Extraction)?

TESE stands for Testicular Sperm Extraction. It is a procedure in which a small piece of testicular tissue is removed and then processed to extract sperm. This procedure is often performed when TESA is unsuccessful or when there is a complete absence of sperm in the ejaculate.

What is MESA (Microsurgical Epididymal Sperm Aspiration)?

MESA stands for Microsurgical Epididymal Sperm Aspiration. It is a procedure in which a fine needle is used to aspirate sperm from the epididymis, a coiled tube that sits on the top of the testicle. This procedure is often performed when there is no sperm in the ejaculate or when the sperm count is very low.

What is PESA (Percutaneous Epididymal Sperm Aspiration)?

PESA stands for Percutaneous Epididymal Sperm Aspiration. It is a procedure in which a fine needle is used to aspirate sperm from the epididymis. This procedure is similar to MESA, but it is often performed using a less invasive technique.

Choosing the Right Procedure

The choice of procedure will depend on several factors, including the cause of infertility, the quality of the sperm, and the patient's preferences. In some cases, a combination of procedures may be necessary.

FAQs

1. Are these procedures painful?

Both TESA and PESA are usually performed under local anesthesia, which minimizes discomfort. TESE, being more invasive, may involve some pain after the procedure, but this can be managed with pain relief medication. Most patients report only mild discomfort during and after the procedures.

2. How long does recovery take after these procedures?

Recovery time varies by procedure:

• TESA and PESA: Recovery is typically quick, often allowing patients to resume normal activities within a day or two.
• TESE and MESA: Recovery may take a bit longer, generally a few days to a week, depending on individual healing.

3. How successful are these sperm retrieval techniques?

The success rates of these techniques depend on various factors, including the underlying cause of infertility, the man’s age, and the quality of the retrieved sperm. Consulting with a fertility specialist can provide a better understanding of what to expect based on individual circumstances.

4. Can sperm retrieved using these methods be used for IVF?

Yes, sperm retrieved through TESA, TESE, MESA, and PESA can be used for In Vitro Fertilization (IVF) procedures. The retrieved sperm can be used to fertilize the eggs in the lab, making these techniques critical for couples facing male factor infertility.

5. How do I know which procedure is right for me?

The best way to determine the appropriate sperm retrieval technique is to consult with a fertility specialist at New World Fertility Centre. They will evaluate your medical history, perform necessary tests, and recommend the most suitable procedure based on your specific situation.
