This technique is recommended when the diagnosis confirms the absence of sperm in the ejaculate. The urologist will carry out a study to determine possible causes, a series of tests will be done, which include a genetic study and hormone testing.

If all these parameters are favorable, we will proceed to perform a testicular biopsy, in order to retrieve sperm from testicular tissue. Testicular biopsy is a procedure that removes a small portion of the testis to be examined. It is performed by making a small incision in the skin of the scrotum. It removes a small portion of testicular tissue through the incision thus obtaining a sample. The sperm obtained can be used in an In Vitro Fertilization cycle.
