Why is ICSI the only technique that can be used in cases of testicular biopsy?

In cases of testicular biopsy, ICSI must be used as an oocyte insemination technique, because these are immature spermatozoa that have not matured physiologically on their way to the epididymis. Moreover, the sperm count after the biopsy is usually low, insufficient for artificial insemination or conventional IVF.
