Azoospermia is the total absence of spermatozoa in the ejaculate. Azoospermia is found in 10% to 15% of male infertility cases and is caused by a testicular insufficiency in the majority of patients. Obstructive azoospermia is less frequent and arises in 15-20% of men with azoospermia. Most causes of male infertility are treatable, and many treatments restore the ability to father a children naturally. In case of vasal or epididymal obstruction, microsurgical reconstruction of the seminal pathways, if possible, remains the safest and most cost-effective treatment option for these patients, allowing natural conception in many cases. Not all men with obstructive azoospermia are tractable by microsurgical reconstruction. In such situations, various sperm-retrieval techniques can be employed to take sperm for use with in vitro fertilization via intracytoplasmic sperm injection.

Abstract
Azoospermia is the total absence of spermatozoa in the ejaculate. Azoospermia is found in 10% to 15% of male infertility cases and is caused by a testicular insufficiency in the majority of patients. Obstructive azoospermia is less frequent and arises in 15-20% of men with azoospermia. Most causes of male infertility are treatable, and many treatments restore the ability to father a children naturally. In case of vasal or epididymal obstruction, microsurgical reconstruction of the seminal pathways, if possible, remains the safest and most cost-effective treatment option for these patients, allowing natural conception in many cases. Not all men with obstructive azoospermia are tractable by microsurgical reconstruction. In such situations, various sperm-retrieval techniques can be employed to take sperm for use with in vitro fertilization via intracytoplasmic sperm injection.Pubblicazioni consigliate
