PESA and TESA

Q: How are these procedures performed

The procedures for PESA and TESA are very similar PESA: PESA is performed under local anesthesia i.e. anesthetics are injected directly into the scrotum to make the area numb. The vas deferens is located.A small needle is inserted into the vas deferens or epididymis and the plunger is pulled to extract the seminal fluid.The testis is examined to locate any abnormality or blockage in the vas deferens. Before examination, the scrotum is swabbed with a warm antiseptic to prevent infection. The retrieved seminal fluid is checked for sperm motility and shape.The process is repeated until enough sperms are collected. TESA: If no sperm is retrieved through PESA, it indicated that the vas deferens did not have any sperm and TESA is performed to extract the sperms directly from the testis. A small needle is inserted into the testicles and testicular tissue is aspirated. Sufficient amount of sperm is required for further procedures.

Benefits of PESA AND TESA

Most of the men suffering from infertility assume that they are completely sterile and they can never become a father. However, this is not completely true. Most of the (so called infertile) males do not have complete azoospermia. There are various causes of infertility. It may be blockage of ducts (Vas deferens, epididymis), insufficient number of healthy sperms, low motility of sperms, dilated veins in scrotal area, retrograde ejaculation etc.

With the help of some tests, sperms can be collected directly from epididymis (PESA) or testes (TESA) and it can be decided more accurately where exactly the problem lies. In case of issues like motility, low count of healthy sperms, retrograde ejaculation or hormonal cause, IVF or in vitro fertilization maybe be helpful.

Success of PESA AND TESA

PESA and TESA are treatment options available for males suffering from obstructive or non-obstructive oligozoospermia. The success rates of these procedures depend on the individual males. The associated success rate is about 25% for every cycle of treatment.

HOW PESA AND TESA IS PERFORMED?

The procedure of TESA and PESA are given below:

PESA

PESA is performed under local anesthesia i.e. anesthetics are injected directly into the scrotum to make the area numb. This is done to avoid any pain during the procedure.
The vas deferens is located.
A small needle is inserted into the vas deferens or epidydimis and the plunger is pulled to extract the seminal fluid.

TESA

If no sperm is retrieved through PESA, it indicated that the vas deferens did not have any sperm. And hence TESA needs to be performed to extract the sperm directly from the testis.
A small needle is inserted into the testicles and testicular tissue is aspirated. Sufficient amount of sperm is required for further procedures.
