Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

The Spectrum of Congenital Hypogonadotropic Hypogonadism: A 30‐Year Experience at a Tertiary Paediatric Centre

Clinical Endocrinology, EarlyView.
ABSTRACT Congenital hypogonadotropic hypogonadism (CHH) is a rare group of disorders of gonadotropin deficiency, either isolated or as a part of multiple pituitary hormone deficiencies (MPHD). We aimed to describe the spectrum of presentation, diagnosis, and management practices of CHH spanning 30 years at an Australian tertiary paediatric centre. This

Current Approaches to Support Patients to Withdraw From Image and Performance Enhancing Drugs

Clinical Endocrinology, EarlyView.
ABSTRACT Image and performance‐enhancing drugs (IPEDs) include agents such as androgens, growth hormone, and erythropoietin, which are used to enhance appearance and physical performance. Androgens, also known as anabolic‐androgenic steroids (AAS), are the most used IPEDs worldwide.

High Uric Acid Promotes Stem Leydig Cell Senescence by CCDC90B Mediates Mitochondrial Quality Control Imbalance

Cell Proliferation, EarlyView.
In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

Biochemical profiling and symptomatology of androgen deficiency in males with cluster headache: A prospective case–control study

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objectives/Background Cluster headache (CH) has historically been considered a male‐dominated disorder, suggesting a role for androgens in its pathophysiology. We aimed to evaluate hormone profiles and symptoms of androgen deficiency in CH.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.
