Relevance of testicular histopathology on prediction of sperm retrieval rates in case of non-obstructive and obstructive azoospermia

, 2018
Introduction: The aim of our research was to establish the relevance of testicular histopathology on sperm retrieval after testicular sperm extraction in patients with non-obstructive azoospermia and in patients with obstructive azoospermia, who already ...

A comparison of the expression patterns and diagnostic capability of the ncRNAs NEAT1 and miR-34a in non-obstructive azoospermia and severe oligospermia

Human Genomics
Infertility is a major global health problem, affecting 8–12% of couples worldwide, with male causes contributing to approximately 50% of cases. Notably, around 15% of infertile men are azoospermic.

Cryopreservation of testicular and epididymal sperm: techniques and clinical outcomes of assisted conception

Clinics, 2013
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of

Azoospermia

, 2015
Azoospermia is defined as the complete absence of sperm in the ejaculate even after centrifugation. With a prevalence of 1 % among the general male population and 10-15 % among infertile men, it can be classified in two large groups: Obstructive and non ...

[Obstructive azoospermia and malformations of seminal tract].

Archivio italiano di urologia, andrologia : organo ufficiale [di] Societa italiana di ecografia urologica e nefrologica, 1996
About 10% of the cases of male infertility is represented by the obstruction of the seminal tract, which may be congenital or secondary to inflammatory events or surgery. The most frequent obstructive malformation of the seminal tract is the bilateral agenesia of the vas deferens.

Cyto- and Histopographic Assessment of CPA3-Positive Testicular Mast Cells in Obstructive and Non-Obstructive Azoospermia

Infertility is an important personal and society disease, of which the male factor represents half of all causes. One of the aspects less studied in male infertility is the immunological testicular microenvironment.
