TESR/PESA (Surgical Sperm Retrieval)

PESA is known as Percutaneous Epididymal Sperm Aspiration (PESA). With the advent of intracytoplasmic sperm injections, the use of non-ejaculated sperm and azoospermic male partners seeking biological children has become a global procedure. In such patients, spermatozoa can be retrieved surgically from the epididymides and testes. 

Testicular Sperm Extraction (TESE) - Testicular tissue is usually removed for sperm search and isolation in patients who have failed PESA and have proven obstructive azoospermia. A standard open surgical biopsy technique is used to remove the testicular tissue without the use of optical magnification in conventional TESE. This is an outpatient procedure that is minimally invasive.

There are numerous surgical sperm retrieval methods available. Pre-procedure testing is required to determine the best method for sperm retrieval. It is also necessary to test whether the testicles produce sperm. The following are examples of cases in which sperm can be extracted surgically from the testicles:

• Physical impediments impede sperm production.
• The man had a vasectomy that could not be undone.
• The man lacks vas deferens.
• There is a blockage in the tube that transports sperm from the testicles to the penis, which could be the result of testicular cancer. In such cases, the sperm must be extracted before cancer treatment can begin.
