Testicular Sperm Aspiration

Testicular Sperm Aspiration

Testicular Sperm Aspiration and biopsy refer to a specialized technique for sperm extraction that is utilized to treat severe issues relating to male-factor infertility. However, depending on the diagnosis and tests, the doctor or healthcare specialist may suggest a variety of infertility techniques to help and treat the issue.

Methods of Surgical Sperm Retrieval

When it comes to some infertility problems, there are a couple of methods for surgical sperm retrieval that are available and these include the following:

1. MESA – which is generally called Microsurgical Epididymal Sperm Aspiration.

2. PESA – or Percutaneous Epididymal Sperm Aspiration.

3. TESE – or also known as the Testicular Sperm Extraction Microdissection

4. Testicular Sperm Aspiration – Testicular Sperm Aspiration; this procedure includes the TFNA or the Testicular Fine Needle Aspiration.

5. TESE – Perc biopsy; which is a percutaneous biopsy of the testis.

Which method to use will all depend on the nature of the issue, and this needs to be thoroughly examined and tested by the healthcare specialist or doctor first.

Testicular Sperm Aspiration

TESA or Testicular Sperm Aspiration can be utilized as a form of diagnostic measure that can detect a condition in males that is called azoospermia – a problem when males do not have any sperm in his seminal fluid. TESA can also be used to help in the recovery of sperm from a man’s testicles, especially if he has ejaculatory problems or obstructions that cannot really be treated by any other available methods.

During the Testicular Sperm Aspiration, an extremely fine needle will be slipped into the testicles (of course, under anesthesia) to retrieve a very small amount of material from the male’s seminiferous tubules – little tubes where sperms are mainly created. After the extraction, the tubules will be processed thoroughly in a lab then examined for any presence of sperm which can either be used to fertilize eggs or to be kept frozen for future use.

Extracted sperm via the Testicular Sperm Aspiration procedure are considered less motile and mature compared to sperm in ejaculated seminal fluid; as such, ICSI or Intracytoplasmic Sperm Injection is necessary to achieve proper fertilization with the sperm acquired through Testicular Sperm Aspiration.

Testicular Sperm Aspiration Procedures

ICSI has generally transformed the treatment process of male infertility which is why the sperm necessities for egg fertilization have plummeted; the drop ranged from hundreds of thousands for the IVF procedure to a single viable sperm needed for the ICSI and IVF procedure. This has led to the creation of new surgical techniques that are aggressive enough to offer quality sperm to use for egg fertilization. This is best for men who have little to no sperm count.

Testicular Sperm Aspiration methods usually involve the utilization of minor surgical procedures to gather sperm from organs located in the genital tract. The methods are generally for men who are unable to transport sperm since the ductal system that usually brings the sperm to the ejaculate is missing.

It is vital to know that during the IVF procedure, it is necessary to achieve pregnancy via most of these extraction methods; this is the reason why success rates are generally connected to a complementary and complicated set of programs for assisted reproduction for the couples.

Side Effects of Testicular Sperm Aspiration

Just like every other type of surgery that is available, there will always be a possibility that one may experience forms of side effects, problems, and complications; some of these side effects may include pain, bleeding, discomfort, bruising, and even the risk of getting an infection. Remember that if the sperm retrieval procedures are more invasive, these are more susceptible to various side effects and may require the patient to stay overnight in the hospital. The patient will be provided with some antibiotics to avoid further occurrences of infections while pain medications or relievers can aid in the management of any type of soreness of the treated area.


A lot of azoospermic males that go through NOA or non-obstructive azoospermia are possible candidates for sperm aspiration which is part of the process of IVF. Since sperm may possibly be present in a few, but not all parts of the testes, multiple samples of the testicular tissues are carried out to boost the chances of finding sperm in the NOA individuals.

The samplings can be executed via two methods and these include the TESA or theTESE (testicular sperm extraction); sperm extraction is performed more often by andrologists and a lot of these specialists prefer Testicular Sperm Aspiration, given that these individuals are not trained surgically.
