Secretory azoospermia or non-obstructive azoospermia? [PDF]
In the non-obstructive azoospermia versus the secretory azoospermia it is first necessary to have a clear assessment and definition and then takes care of the patient before the surgical sampling taking into account the age of the woman and in fine try ...
