TESA stands for Testicular Sperm Aspiration and PESA stands for Percutaneous Epididymal Sperm Aspiration. TESA is usually a little more complex as compared to PESA and is performed if there is no sperm found within the epididymis, thus prompting a needle to be inserted directly into the testicles.

Benefits of TESA and PESA

Most men who suffer from infertility usually assume that they are completely sterile and they can never father a child that is genetically their own. What most of them forget is that there could be a condition preventing sperm from getting out of their reproductive system during ejaculation. PESA and TESA will determine exactly where the issue is and solve it by retrieving sperm from the epididymis or testicles via a thin needle. TESA and PESA are performed under anaesthesia and are relatively painless techniques that make it possible for a couple to achieve pregnancy with their own sperm.



PESA involves passing a fine needle through the skin into the epididymis to obtain sperm. TESA involves passing a fine needle through the skin directly into the testes and retrieving a small number of the seminiferous tubules themselves. The tubules are then dissected in the laboratory and the contents searched for the presence of sperm.

Both of these surgical procedures can be performed under either local anaesthetic or sedation. You can Consult us to know which approach is suitable for you.
