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 ...

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

Andrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

Choriocarcinoma-like human chorionic gonadotrophin (HCG) and HCG bioactivity during the first trimester of pregnancy.

, 2000
The objective of this study was to evaluate the distribution of choriocarcinoma-like human chorionic gonadotrophin (HCG) isoforms during first trimester pregnancy and their relationship with in-vitro HCG bioactivity.

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

Andrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Neoplastic Risk in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Besides gonadal involvement (hypogonadism, male factor infertility, and testicular hypotrophy), patients with Klinefelter syndrome (KS) may suffer from several extra‐gonadic complications, including neoplastic events. Objective The aim of this review is to summarize all major clinical evidence dealing with the association between KS

Parallel Liquid Biopsy Analysis of miR‐371a‐3p and Cell‐Free DNA in an Unselected Cohort of Patients With Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background Despite robust data showing strong potential to improve diagnosis and disease monitoring in testicular germ cell tumors (TGCTs), miR‐371a‐3p testing has not yet been implemented in routine clinical practice. Cell‐free DNA (cfDNA) represents another promising liquid biopsy biomarker that may provide complementary molecular ...

Sex Steroids Measurement by Mass Spectrometry in Hypogonadal Men in a Real‐World Setting: Serum Estradiol (E2) and E2 to Total Testosterone Ratio Do Not Differ Between Patients With Klinefelter Syndrome and Non‐Klinefelter Syndrome Hypogonadism

Andrology, EarlyView.
ABSTRACT Background Traditionally, Klinefelter syndrome (KS) was considered a clinical condition associated with hyperestrogenism. Aim To compare circulating sex steroids, particularly estrogens, in a cohort of KS and non‐KS hypogonadal men. Materials and Methods A cohort of hypogonadal men, treated and untreated, was prospectively enrolled in a real ...
