Tanner stages of thelarche in relation to anthropometric and ultrasound predictors in premenarcheal girls

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
We found a close correlation between thelarche and internal genital maturation on pelvic ultrasound, paralleling Tanner breast stages and supporting the concept of correlated external and internal pubertal development. Abstract Introduction Thelarche is often the first sign of puberty initiation in girls.

FSH regulation of sertoli cell functions and response

, 1982
International audienceAndrogens from the leydig cells in combination with FSH regulates spermatogenesis via the sertoli cell. FSH binding to specific membrane receptors activates adenylyl cyclase and protein kinase with subsequent influence on protein ...

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 ...

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.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

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.

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...
