Testicular Biopsy and Vasography
Testis biopsy is performed to identify the quality of spermatogenesis in patients who may have obstructive male infertility or to identify the presence of testicular sperm cells, which may be aspirated and used for intracytoplasmic sperm injection (ICSI). Testis biopsy may also be used to identify the presence of round spermatids, which may be aspirated and used for round spermatid nuclear injection (ROSNI).
