The harvesting of sperm by the use of surgical techniques is done for several reasons. Some of these include:

    • If a man is unable to ejaculate successfully

    • If there is an obstruction present in the tubes that carry the sperm outwards

    • A case of a failed Vasectomy reversal

There are two techniques that exist for Surgical Sperm Retrieval – PESA and TeSA. These techniques are routinely performed and allow the patient to return to work the following day.

Percutaneous Epididymal Sperm Aspiration (PESA)

If a blockage in the epididymis or congenital absence of the vas deferens (the drainage tube for sperm from the testis to the penis), is the cause for Azoospermia (no sperm in the semen), then this procedure is indicated for obtaining sperm

Testicular Sperm Aspiration (TeSA)

In some men, the production of sperms in the testis is very low and no sperms are seen in the semen. TeSA is a way of obtaining the few sperms that are available in the testis.
