TESA PESA Treatment

TESA PESA Treatment are the ideal treatment options for men suffering from azoospermia, Vasectomy, or a testicular tube blockage. These TESA and PESA techniques help in retrieving sperm.

It is painless and takes about 30 minutes to collect the sample. In this surgical treatment, general anesthesia is given to the male. Then a tiny needle is inserted into the reproductive organ to collect the sperm cells from the testicles or epididymis.

What is TESA?

TESA stands for Testicular Sperm Aspiration. It is an assistive reproductive procedure performed for men to retrieve sperm for IVF or ICSI. A needle attached to a syringe is inserted in the testicles, and sperms are aspirated. Compared to PESA, TESA is more complex. It is usually performed when there is no sperm found within the epididymis.


What is PESA?

PESA stands for Percutaneous Epididymal Sperm Aspiration. It is less complicated than TESA as in this treatment doctor directly inserts a needle into a man’s epididymis, the tube connecting the testicles to retrieve the sperm. It is done with local anesthesia in the operating room or clinic and is coordinated with the female partner’s egg retrieval.

When TESA PESA Treatment are Performed?

TESA and PESA are usually performed when men are not able to release sperm via ejaculation naturally. It may be because of the blockage of the vas deferens or epididymis. In TESA, sperm is collected directly from the testicles, and in PESA, it is collected from the epididymis.

Following are the conditions in which TESA PESA Treatment are performed: –


Azoospermia is a condition in which men’s ejaculation contains no sperm. It is 10 to 15% of the cause of male infertility. It can be because of the blockage in the men’s reproductive system or maybe because of the low production of sperm in the testes.

Azoospermia can be of two types obstructive or non-obstructive. Whatever azoospermia obstructive or non -obstructive men are suffering, depending on the severity, sperm can be retried using TESA PESA Treatment.

  • Vasectomy
  • Infections
  • Inflammation
  • Trauma or Injury in these areas
  • Previous Surgeries in the Pelvic Area
  • Development of a Cyst
  • Cystic Fibrosis Gene Mutation

Testicular Failure

Klinefelter’s syndrome or other abnormalities of the y chromosome leads to testicular failure. It reduces the ability of the testicles to produce and store enough sperm that can go into the women’s uterus during sexual intercourse. In such conditions, these TESA and PESA can be used to collect sperm from the epididymis or testicles.


Varicocele is a condition characterized by benign testicular cysts. A group of varicose veins growing within the epididymis can give rise to varicocele. It may cause a blockage that obstructs the flow of sperm out of the epididymis and testicles. TESA and PESA work best for a man suffering from this condition.

Steps Involved in PESA

1. Administration of Anesthesia

PESA is performed by giving local anesthesia directly into the scrotum. This numbs the area and prevents the pain sensation during the whole procedure.

2. Examine the Testes

The doctor will then do antiseptic swabbing of the scrotum to disinfect the area before the procedure. Then will examine the testes and locate the vas deferens to detect any blockage or abnormalities.

3.Sperm Extraction

After locating the vas deferens, the doctor inserts a small needle into the vas deferens or epididymis. Then using a syringe doctor aspirates the seminal fluid from the epididymis.

4. Examine the Sperm

After retrieving the seminal fluid doctor examines for healthy and motile sperm. Doctors can repeat the complete PESA procedure till they do not find adequate sperm.

What is the TESA Procedure?

TESA is performed if, after the PESA process doctor cannot retrieve sperms from the vas deference or epididymis.

In this TESA procedure, a small needle is inserted directly through the testes into the testicular tissue and aspirates the tissue. Sufficient quantity and quality of sperms are retrieved just like PESA. And the doctor may repeat the procedure till he recovers an adequate number of healthy sperm for fertilization.

Benefits of TESA PESA Treatment

TESA and PESA are excellent treatments for men’s infertility. The process may be a little painful, but these can make it possible for a man to get their woman pregnant through IVF and have their genetic baby. PESA and TESA also determine precisely where the issue is and solve it by retrieving sperm from the epididymis or testicles via a thin needle.

Recovery time for TESA PESA Treatment

A male who has undergone a TESA or PESA usually takes a day to recover fully, as both are outpatient procedures. After the procedure doctor may advise you to wear tightly fitted pants to support your scrotum. You may also be given painkillers if there is any pain.

Success Rate of TESA PESA Treatment

TESA and PESA technique is a unique fertility treatment for men suffering from azoospermia. The success rate of TESA is 80 to 90%, and PESA is 70 to 80%. However, PESA is most preferred by patients because they can return home within an hour and return to work the next day.
