MRI in the evaluation of the azoospermic male
Diagnostic and Interventional Radiology, 2020 PURPOSEWe aimed to show the usefulness of magnetic resonance imaging (MRI) in the evaluation of infertile men and its ability to distinguish obstructive from nonobstructive azoospermia.

Prognostic factors for sperm retrieval in non-obstructive azoospermia [PDF]
, 2013 Testicular sperm retrieval techniques associated with intracytoplasmic sperm injection have changed the field of male infertility treatment and given many azoospermic men the chance to become biological fathers.

Value of Serum Inhibin B as a Prognostic Factor in Patients with Non-obstructive Azoospermia [PDF]
, 2023 Background: Non-obstructive Azoospermia (NOA) mean absence of sperm in the ejaculate due to testicular failure. The sole treatment till now for them is testicular sperm retrieval and ICSI.

Isodicentric Y Chromosomes and Sex Disorders as Byproducts of Homologous Recombination that Maintains Palindromes [PDF]
, 2009 Massive palindromes in the human Y chromosome harbor mirror-image gene pairs essential for spermatogenesis. During evolution, these gene pairs have been maintained by intrapalindrome, arm-to-arm recombination.

Andrologia, 2023 Azoospermia is a severe problem that prevents couples from having their own children through natural pregnancy. In nonobstructive azoospermia (NOA), microdissection testicular sperm extraction (micro-TESE) is required to collect sperm and, at 40%–60 ...

Mutations in SOHLH1 gene associate with nonobstructive Azoospermia
Human Mutation, 2010 In a previous study, we found SOHLH1 (spermatogenesis and oogenesis-specific basic helix-loop-helix 1) as the first testis-specific basic helix-loop-helix transcription factor essential for spermatogonial differentiation. SOHLH1 therefore represents an excellent candidate gene for testicular failure such as nonobstructive azoospermia (NOA). We analyzed

The epidemiology and etiology of azoospermia [PDF]
, 2013 The misconception that infertility is typically associated with the female is commonly faced in the management of infertile men. It is uncommon for a patient to present for an infertility evaluation with an abnormal semen analysis report before an ...

Emerging trends in the management of non‐obstructive azoospermia
UroPrecision, Volume 3, Issue 2, Page 88-97, June 2025.Abstract Ten percent of infertile males have azoospermia, classified into obstructive and nonobstructive types, which require specific medical or surgical treatments. In nonobstructive azoospermia, advancements in microsurgery allow for effective sperm retrieval in about half of cases.
