Ring Chromosome 11 may be linked to conditions like early puberty, excessive hair growth, hair loss, and type 2 diabetes.
research Parathyroid adenoma with coeliac disease: primary or quaternary hyperparathyroidism? Gruczolak przytarczyc i choroba trzewna: pierwotna czy czwartorzędowa nadczynność przytarczyc?
A gluten-free diet and removing the parathyroid adenoma helped a girl with coeliac disease and high calcium levels start puberty.
research Insights learned from L457(3.43)R, an activating mutant of the human lutropin receptor
The L457(3.43)R mutation in the human lutropin receptor causes increased activity and hormone insensitivity, leading to precocious puberty.
research Acne: Transient Arrest in the Homeostatic Host–Microbiota Dialog?
Acne is a temporary skin imbalance during puberty that often resolves on its own.
research Epigenetic regulation of 5α reductase-1 underlies adaptive plasticity of reproductive function and pubertal timing
Environmental factors affect reproductive traits by altering the SRD5A1 gene.
research Glucocorticoid Receptor Mutants Demonstrate Increased Motility Inside the Nucleus of Living Cells: Time of Fluorescence Recovery After Photobleaching (FRAP) Is an Integrated Measure of Receptor Function
Certain defective glucocorticoid receptor mutants move faster inside cell nuclei and work less effectively.
research Premature adrenarche, polycystic ovary syndrome and intrauterine growth retardation: does a relationship exist?
Low birthweight and rapid weight gain after birth may increase the risk of developing polycystic ovary syndrome.
research Is there a role for dermatologists in eating disorders?
Dermatologists can help detect and manage eating disorders by recognizing skin changes.
research Disorders of ovulation
Ovulation disorders are a major cause of infertility and menstrual problems in women.
research Demonstrating individualisation in acne vulgaris: Evidence from homoeopathic case management
Individualized homeopathic treatment improved acne when conventional methods failed.
research Endocrinology Overview RSS
The document explains how male reproductive hormones work and affect the body.
research Androgenic and anti-androgenic effects of progesterone derivatives with different halogens as substituents at the C-6 position
Different halogens on progesterone derivatives can either block or mimic male hormone effects, depending on their type and amount.
research Developmental origin of polycystic ovary syndrome - a hypothesis
The hypothesis suggests that PCOS may start early in life due to genetic and environmental factors, influencing future reproductive and metabolic problems.
research External genitalia abnormalities in male rats exposed in utero to finasteride, a 5α-reductase inhibitor
Finasteride exposure in pregnancy causes genital abnormalities in male rats.
research Differences in Expression of Specific Biomarkers Distinguish Human Beard from Scalp Dermal Papilla Cells
Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.
research Hyperandrogenism in a set of triplets with modification of clinical course by hyperthyroidism
Hyperthyroidism can hide signs of high androgen levels in females.
research Stem Cell Heterogeneity and Plasticity in Epithelia
Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
research Neuroimmunoregulation of Androgens in the Adrenal Gland and the Skin
Cytokines and neuropeptides are key in controlling androgen levels, affecting skin and hair conditions.
research It’s X-Related: Biological Bases of Increased COVID-19 Morbidity and Mortality in Men
Men have worse COVID-19 outcomes than women due to genetic and hormonal differences.
research The Androgen Excess and PCOS Society criteria for the polycystic ovary syndrome: the complete task force report
The report concludes that PCOS is mainly a condition of excess male hormones and its definition may change as new information is discovered.
research The Keratins of the Human Beard Hair Medulla: The Riddle in the Middle
Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.
research Molecular signaling in feather morphogenesis
Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.
research Presence of polycystic ovary syndrome is associated with longer anogenital distance in adult Mediterranean women
Women with polycystic ovary syndrome tend to have a longer distance between the clitoris and anus.
research Becker's nevus associated with chromosomal mosaicism and congenital adrenal hyperplasia
High androgen levels and genetic factors likely cause Becker's nevus and related symptoms.
research Manifestation of Hyperandrogenism in the Continuous Light Exposure-Induced PCOS Rat Model
Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.
research Altered brain and pituitary androgen metabolism by prenatal, perinatal or pre- and postnatal finasteride, flutamide or dihydrotestosterone treatment in juvenile male rats
Treatment during development affects hormone balance and sexual behavior in male rats.
research Oligomenorrhoea in Exercising Women
Irregular menstrual cycles in exercising women may be linked to energy deficiency or hormonal imbalances, requiring careful diagnosis for proper treatment.
