The Impact of Metformin on Plasma Prolactin Levels in Antipsychotics‐Treated Men With Hyperprolactinemia and Early‐Onset Androgenic Alopecia

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Metformin decreases elevated levels of pituitary hormones. Little is known about the association between the reproductive axis and hormonal effects of this drug. The purpose of our study was to investigate whether activity of the hypothalamic‐pituitary‐gonadal axis determines metformin action on prolactin levels in men with prolactin

Decoding the Molecular Landscape of Prepubertal Oocyte Maturation: GTPBP4 as a Key Driver of In Vitro Developmental Competence

Cell Proliferation, EarlyView.
Transcriptional and translational characteristics during goat oocyte maturation and identification of key factors, including GTPBP4, for prepubertal goat oocyte maturation. ABSTRACT The intricate mechanisms driving oocyte maturation remain only partially understood, especially within the domains of domestic animal reproduction and translational ...

Aetiopathogenesis of infantile epileptic spasms syndrome and mechanisms of action of adrenocorticotrophin hormone/corticosteroids in children: A scoping review

Developmental Medicine &Child Neurology, EarlyView.
Why does infantile epileptic spasms syndrome (IESS) occur with a variety of underlying conditions and why does it respond to adrenocorticotrophin hormone (ACTH)/corticosteroids? Our scoping review summarizes five hypotheses from the literature: gene/epigenetic regulation, stress/HPA axis activation, neuroinflammation/immune function, altered neuronal ...

Erectile dysfunction in dermatology and venereology: From aetiopathogenic mechanisms to practical considerations for dermato‐venereologists

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Multiple inflammatory, infectious and autoimmune dermato‐venereological conditions are associated with erectile dysfunction (ED) due to underlying intricate vasculogenic, neurogenic, endocrine and psychogenic mechanisms. It is recommended that practitioners screen dermatology patients for ED and associated comorbidities, provide personalized lifestyle ...

Vernal growth of vocal control nucleus Area X, but not HVC, precedes gonadal recrudescence in wild black‐capped chickadees (Poecile atricapillus)

Journal of Neuroendocrinology, EarlyView.
According to the longstanding model of vernal recrudescence of the songbird vocal control system, upregulation of the hypothalamic‐pituitary‐gonadal axis, and specifically testosterone (T), promotes growth first of HVC, and then Area X. In this study, we show that in black‐capped chickadees, Area X is already fully recrudesced ahead of HPG axis ...

The gut‐microbiota‐brain axis: Focus on gut steroids

Journal of Neuroendocrinology, EarlyView.
Abstract There are over 1000 varieties of steroids that have been reported in nature, including the endogenous sex steroid hormones (i.e., progesterone, testosterone, and 17β‐estradiol) and corticosteroids which are mainly synthesized by gonads and adrenals, respectively.

Neuroactive steroid exposure impacts neurodevelopment: Comparison of human and rodent placental contribution

Journal of Neuroendocrinology, EarlyView.
Abstract The placenta is a fetal endocrine organ that secretes many neuroactive factors, including steroids, that play critical roles in brain development. The study of the placenta‐brain axis and the links between placental function and brain development represents an emerging research area dubbed “neuroplacentology.” The placenta drives many ...

Pituitary gonadotropin‐releasing hormone II as a possible mediator of positive estrogen feedback

Journal of Neuroendocrinology, Volume 37, Issue 4, April 2025.
Abstract It has previously been shown that rhesus macaques express two forms of gonadotropin‐releasing hormone (GNRH1 and GNRH2) in the hypothalamus and that both forms can stimulate the release of luteinizing hormone (LH) in vivo. However, while much has been published about the role of GNRH1 in reproduction, very little is known about the ...

Hypotheses in light detection by vertebrate ancient opsin in the bird brain

Journal of Neuroendocrinology, EarlyView.
Abstract Extra‐retinal photoreception is common across fish and avian species. In birds, the hypothalamus contains non‐visual photoreceptors that detect light and regulate multiple endocrine systems. To date, light‐dependent control of seasonal reproduction is one of the most well‐studied systems that require deep brain photoreception.
