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,
