This review discusses the biology of spermatogenesis and male reproductive toxicology but reports no new research findings.

This case study observed that long-term itraconazole and budesonide use in a cystic fibrosis patient led to iatrogenic Cushing's syndrome due to inhibited metabolic clearance of budesonide, suggesting a need for regular adrenal insufficiency monitoring in such treatments.

This paper reviews Ayurveda and Yoga as holistic approaches for managing PCOS, highlighting their potential efficacy in restoring hormonal balance and improving reproductive health but reports no new clinical results.

In this study, a patient with cystic fibrosis developed iatrogenic Cushing's syndrome due to impaired clearance of budesonide from concurrent itraconazole use, highlighting the need for regular monitoring in such combination therapies.

This case report details a diagnosis of adult-onset isolated hypogonadotropic hypogonadism in a 23-year-old African American female, highlighting its genetic basis and treatment approach.

This review compiles the anatomical, histological, and physiological characteristics of various human body follicles, highlighting potential avenues for future research, but does not report new clinical results.

Finasteride affects prostate weights and pituitary activity differently with age.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This study found that dihydrotestosterone treatment in female rats altered anterior pituitary gland gene expression, with significant repression of prolactin and inhibition of GnRH receptor gene expression, suggesting specific hormone production changes.

In this study, plasma levels of MSH and cortisol in patients with alopecia areata did not show significant changes compared to healthy controls.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This study found that trilostane was effective in resolving symptoms such as polyuria and polydipsia in many dogs with pituitary-dependent hyperadrenocorticism, with significant hormone level reductions observed.

This study found trilostane to be an effective and generally safe treatment for improving symptoms in dogs with pituitary-dependent hyperadrenocorticism.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This study suggests that chronic stress can lead to decreased skin pigmentation in mice by disrupting the skin's HPA axis, potentially making stress a risk factor for depigmentation.

This research highlighted that the gut microbiota may influence ovarian health, suggesting it could be used as a biomarker for early diagnosis and treatment of diseases like PCOS, ovarian insufficiency, and ovarian cancer due to its impact on hormone levels.

This study found that gonadal dysfunction is very common in premenopausal women with acromegaly and may be caused by hyperprolactinemia, GH/IGF-I excess, or tumor effects.

This study found that while isotretinoin lowered levels of female hormones in patients with severe acne, it did not significantly impact ovarian reserve function.

This review discusses the negative health impacts of testosterone deficiency and the potential adverse effects of 5α-reductase inhibitors, emphasizing the need for patient-physician discussions regarding these treatments.

This review describes recent advances in regenerating functional 3D organs from stem cells, particularly ectodermal organs, but reports no new clinical findings and highlights future research directions for organ replacement therapy.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This review highlights the efficacy of transdermal testosterone therapy in improving sexual function in women with hypoactive sexual desire disorder, though approved formulations and long-term safety data are limited.

This study found that women with PCOS who have an exaggerated 17-hydroxyprogesterone response to buserelin exhibit more severe hyperandrogenemia, increased insulin secretion, and reduced insulin sensitivity.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.

This study suggests that targeting olfactory receptors in the lung epithelium might help treat odorant-induced asthma in cases without type 2 inflammation, as these receptors could play a role in airway sensitivity to smells.

This study discusses the complex roles and effects of brain-synthesized sex neurosteroids, highlighting sex differences in their concentrations and their varied impacts on synaptic plasticity, cognitive behavior, and aging-related cognitive decline.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.
