About Microsurgical Testicular Epididymal Sperm Extraction (Micro TESE)/ Sperm Retrieval

Micro TESE is a process performed when the sperm count is low and so cannot be thus ejaculated. The procedure of micro TESE is for men who are azoospermic or have a problem with sperm production. By using general anaesthesia, in an operating room under the operating microscope, the procedure is carefully performed. Micro TESE is coordinated with that of the egg retrieval of the female partner. It allows them to be with each other as it is however done a day before egg retrieval. It is a safer procedure because fewer testicular tissues are removed from it. 

Patients who have NOA, might not be able to detect sperm on a semen analysis, there might be primary areas to produce sperm within the testis. Typically, a surgeon spends numerous hours in search of sperm with the help of an operating microscope. However, the surgical field makes the process 10 to 15 times more magnificent. The sperm collected can be directly used in case of availability of fresh and frozen oocytes or else sperm can be frozen. Intracytoplasmic sperm injection or ICSI is the procedure for directly injecting sperm into the eggs or fertilization of eggs. The process poses a financial barrier as it is costly and rates of sperm retrieval are 40-60% for micro TESE.
