Predictors of testicular sperm retrieval in patients with non-obstructive azoospermia: a review
Journal of International Medical Research, 2021 Azoospermia is divided into two categories of obstructive azoospermia and non-obstructive azoospermia. Before 1995, couples with a male partner diagnosed with non-obstructive azoospermia had to choose sperm donation or adoption to have a child. Currently,

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]
Einstein (São Paulo), 2009 Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ...
