TESA, TESE, Micro TESE for Azoospermia
TESA (Testicular Sperm Aspiration) and TESE (Testicular Sperm Extraction) are procedures used to retrieve sperm from the testicles of men who have azoospermia or very low sperm count. Both TESA and TESE are typically performed as outpatient procedures and are used to collect sperm for use in assisted reproductive techniques such as in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
TESA is a minimally invasive procedure in which a fine needle is used to aspirate (remove) sperm directly from the testicle. It is typically used in men who have azoospermia due to a blockage in the vas deferens (the tube that carries sperm from the testicle to the urethra) or in men who have had a vasectomy.
TESE, on the other hand, is a more invasive procedure in which a small piece of testicular tissue is removed and examined under a microscope for the presence of sperm. It is typically used in men who have azoospermia due to a problem with sperm production in the testicles.
Both TESA and TESE are usually performed under local anesthesia and the success rate of these procedures depend on the underlying cause of azoospermia and the quality of the sperm retrieved.
What is Micro TESE ?
MICROTESE is an advanced technique to retrieve sperms particularly with non obstructive azoospermia. This technique has certain advantages compared to other techniques with some complications too. Dr Arun Muthuvel uses this technique when other simple techniques like TESA fail.
