निल शुक्राणु वाले कैसे अपने शुक्राणु से बने पिता?

Sperm harvesting is entirely different from a diagnostic testicular biopsy because, in this setting, the goal is not to identify what is happening in the testis but instead it is to find sperm. Only men with no sperm in their ejaculate (azoospermia) need to have sperm retrieved directly from the testis or epididymis.
