Introduction The application of microdissection testicular sperm extraction (micro-TESE) to retrieve the sperm of patients with non-obstructive azoospermia (NOA) has greatly increased. Patients with NOA often have poor quality sperm. Unfortunately, there

Difficulties in differential diagnosis between obstructive and non-obstructive azoospermia
Introduction. The difference between obstructive and non-obstructive azoospermia (OA and NOA) is important for the choice of treatment tactics and adequate counseling of a married couple.Objective.

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]
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 ...
