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 ...
