Testicular Extraction of Sperm For Azoospermia

Testicular sperm extraction, or TESE, is a surgical procedure to retrieve sperm directly from the testicles. Sperm extracted directly from testes are then used for In Vitro fertilization (IVF) [1].

This method is particularly helpful for couples trying to conceive but facing male infertility challenges. This procedure is effective for men with azoospermia, a condition where little to no sperm are present in ejaculate [2].

In this article, we will discuss different methods for testicular extraction of sperms. We will also see how effective TESE is for infertile males.

What is Testicular Sperm Extraction (TESE)?

As the name suggests, testicular sperm extraction is a procedure to extract sperm from the testes. It is helpful for men who are unable to ejaculate sperm due to various reasons.

Men with a blockage or absence of vas deferens often require TESE. Vas deference is the tube that carries sperm from the testicles. It is also effective for men with very low sperm counts.

A specialist performs TESE under general or local anesthesia. The choice depends on the specific technique used and the patient's comfort level.

Different TESE Techniques

There are several techniques for sperm retrieval or seman extraction. Which method will work best for you depends on your condition and the expertise of the doctor.

The three main TESE techniques are:

1. Conventional TESE
2. Microdissection TESE (Micro-TESE)
3. Percutaneous Epididymal Sperm Aspiration (PESA)

Let’s discuss the different aspects of TESE techniques in detail:

1. Conventional TESE

Conventional TESE is the most common technique [3]. In conventional TESE, the doctor makes a small incision in the testicles and extracts a small piece of tissue.

The tissue is then examined under a microscope to check the availability of live sperm. Once the live sperms are found, they can be used for In Vitro Fertilization.

Although conventional TESE is easy to perform, it is hard to find a greater number of sperms using this method.

2. Microdissection TESE (Micro-TESE)

Micro-TESE is a more advanced technique in which a high-powered microscope is used to reach the area in the testes where sperm can be present [4]. After finding the sperm-containing tissues, mainly seminiferous tubules, these tissues are extracted through micro-incisions.

Micro TESE procedure is less invasive and can retrieve more sperm cells than conventional TESE. A study by Andrology journal shows that microdissection TESE retrieves about 20% more sperm compared to conventional TESE [5].

Percutaneous Epididymal Sperm Aspiration (PESA)

Percutaneous Epididymal Sperm Aspiration, or PESA, is even less invasive than micro-TESE [6]. PESA involves inserting a needle into the epididymis for testicular sperm aspiration. Epididymis is the tube behind the testes that receive sperm from the testes.

The PESA procedure is convenient for patients but may not suit everyone. This method is commonly effective when sperm production is normal in the testes, but there is some blockage in the vas deferens, preventing the sperm from ejaculation.

3. How Does IVF Work For A Man?

For IVF, you need a live sperm to fertilize the egg in a lab. However, males with azoospermia may not have sperm in the ejaculate. This is where TESE sperm extraction plays a vital role in IVF. This method helps retrieve live sperm from inside the testes to be used for IVF.

For those undergoing fertility treatments, understanding the process of sperm collection for IVF is essential, as it plays a crucial role in ensuring viable sperm are available for fertilization. The extracted sperm through TESE is then combined with a partner's or donor's eggs in a lab. The sperm fertilizes the egg and forms an embryo, which is later implanted into the woman's uterus.

In this way, TESE enables men with specific fertility issues to have biological children.

For men looking to improve sperm health, Conceive Plus Motility Support provides essential nutrients like L-Carnitine and Coenzyme Q10 to enhance sperm motility, a crucial factor in achieving successful fertilization.

Preparing for TESE

Before TESE or surgical sperm retrieval procedure, the doctor will thoroughly evaluate your fertility status and overall reproductive health. This also includes laboratory tests to check hormone levels and imaging tests to examine testes.

For the day of the procedure, the doctor may recommend you eat or avoid a certain diet. You may also need to stop taking certain medications before the procedure, as some drugs can interact with anesthesia [7].

Is Testicular Sperm Extraction Risky?

Like any other surgical procedure, testicular sperm extraction has some risks, such as bleeding and infection. In some cases, it can also cause significant damage to the testicular tissues.

However, the side effects are minimal and can be avoided by following the safety guidelines. Most men recover within a few weeks after the TESE procedure [8].

FAQs

1. How to take out sperm from your body male?

There are different methods to extract sperm from the male body. However, Testicular sperm extraction is the most common method with effective results.

2. Is there any benefit of testicular sperm extraction for fertility?

Testicular sperm extraction provides live sperm that can be used for IVF. In IVF, the extracted sperm fertilizes the egg and makes an embryo.

3. Is TESE a painful procedure?

TESE is usually performed under local or general anesthesia, so you don’t feel pain during the procedure. Some discomfort or swelling can occur after the procedure but typically subsides within a few days.

The Bottom Line

Testicular extraction of sperm is a complex procedure for treating male infertility but has higher success rates. This sperm harvesting or cum extraction procedure involves extracting sperm cells from the testes through incisions or micro-dissections.

The sperm cells are then used for In Vitro Fertilization (IVF). TESE combined with IVF can help an infertile male father to a biological child.
