Multiple azoospermic patients with the non-obstructive azoospermia plan to undergo sperm aspiration as a part of In Vitro Fertilisation Treatment. As the sperms finds their presence in some of the parts of the testes of these infected men, numerous samples are required to perform the test so as to increase the chances of finding the sperms in non-obstructive patients.
What is Micro TESA?
Microscopic TESA also referred to as Micro dissection Testicular Sperm Extraction is the surgical procedure which is performed in the operating room under general anaesthesia in order to retrieve the sperms for IVF. It involves removal of tiny volume of the testicular tissue in the areas of sperm production using the microscope, thus improving the sperm yield. This procedure have the capability to improve the sperm retrieving capacity for men with the non-obstructive azoospermic in comparison to those achieved in past with standard testis biopsy techniques. This particular procedure increases the yield of spermatozoa on one side and on the other side decreases the amount of testicular tissues required and vascular injury created, by making process of identifying blood vessels easily. Sperms collected from the procedure are difficult to cryopreserve for future.
