Multidimensional Determinants of Quality of Life in Men With Klinefelter Syndrome: A Narrative Review of Workshop Evidence

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS), typically characterized by a 47, XXY karyotype, is the most common sex chromosomal aneuploidy in males, with a prevalence of approximately one in 600–660 individuals. Despite its frequency, the syndrome remains significantly underdiagnosed, with 50%–75% of affected individuals never receiving a clinical ...

The Therapeutic Effects of Crocus sativus L. and Its Constituents on the Improving Treatment of Azoospermia: A Narrative Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Azoospermia, defined as the complete absence of sperm in the ejaculate, is a major cause of male infertility and is classified into obstructive and non‐obstructive forms. While obstructive azoospermia is primarily mechanical in origin, non‐obstructive azoospermia (NOA) is characterized by impaired spermatogenesis and is ...

Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, Volume 14, Issue 6, Page 1859-1872, September 2026.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Semen Quality and DNA Fragmentation After Limited Testicular Sperm Extraction in Non‐Azoospermic Men With ART Failure: A Retrospective Matched Cohort Study

Health Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Testicular sperm extraction (TESE) is sometimes used in non‐azoospermic men with persistent infertility, particularly in cases of high sperm DNA fragmentation index (DFI) or repeated intracytoplasmic sperm injection (ICSI) failure.

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

Andrology, Volume 14, Issue 5, Page 1202-1208, July 2026.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Clinical predictors of successful outcomes for couples with nonobstructive azoospermic male partners undergoing micro-TESE

Asian Journal of Andrology
Nonobstructive azoospermia (NOA) is the most challenging and complex clinical scenario for infertile men. Besides circumstances such as hypogonadotropic hypogonadism, surgical sperm retrieval is typically necessary, and microdissection testicular sperm ...

Microsurgical Onco‐Testicular Sperm Extraction in a Patient With Testicular Cancer and Congenital Unilateral Testicular Absence: A Case Report

IJU Case Reports, Volume 9, Issue 3, May 2026.
ABSTRACT Introduction Testicular cancer primarily affects men of reproductive age. Therefore, fertility preservation is important in managing testicular cancer. In patients with a solitary testis, oncological testicular sperm extraction (onco‐TESE) is used to retrieve sperm from tumor‐bearing testis.
