Technologies to improve sperm retrieval in men undergoing micro-TESE for NOA

Asian Journal of Andrology
Nonobstructive azoospermia (NOA) is considered the most challenging clinical scenario for infertile men and current treatments leave many men unsuccessful at being able to achieve a pregnancy with their partner using their own sperm.

Outcomes of Micro-Dissection TESE in Patients with Non-Mosaic Klinefelter’s Syndrome without Hormonal Treatment [PDF]

International Journal of Fertility and Sterility, 2015
Background Klinefelter syndrome (KS) is the most common sex chromosomal disorder in males and historically patients have been labeled as sterile. After the introduction of microdissection testicular sperm extraction (micro-TESE), successful sperm ...

Role of testicular fine‐needle aspiration in the modern male reproductive urologist′s practice

UroPrecision, EarlyView.
Abstract Background Azoospermia affects 10%–15% of infertile men, with non‐obstructive azoospermia (NOA) most often managed by microdissection testicular sperm extraction (mTESE). Despite AUA/ASRM guidelines recommending mTESE, some urologists employ testicular fine‐needle aspiration (TFNA) mapping as a diagnostic adjunct.

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Machine Learning‐Based Prediction of Sperm Retrieval Outcomes in Patients With Klinefelter Syndrome: A Multicenter Study With External Validation

Andrology, EarlyView.
ABSTRACT Background The Klinefelter syndrome is a common genetic cause of male infertility, and testicular sperm extraction (TESE) enables sperm retrieval in a subset of affected patients. However, predicting TESE success remains challenging due to the heterogeneous clinical and endocrinological presentation of the Klinefelter syndrome.

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 ...

Predictive factors of successful microdissection testicular sperm extraction [PDF]

, 2013
Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm in men with obstructive azoospermia approaches >90%, the chances ...

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 ...
