Male pattern hair loss could hint at androgens affecting COVID-19 severity.
research Testosterone alters iron metabolism and stimulates red blood cell production independently of dihydrotestosterone
Testosterone boosts red blood cell production and changes iron metabolism without needing dihydrotestosterone.
research Role of testosterone in SARS-CoV-2 infection: A key pathogenic factor and a biomarker for severe pneumonia
Low testosterone may indicate severe COVID-19 in men.
research The quantification of reproductive hormones in the hair of captive adult brown bears and their application as indicators of sex and reproductive state
Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.
research PLASMA C19 STEROID SULPHATE LEVELS AND INDICES OF ANDROGEN BIOAVAILABILITY IN FEMALE PATTERN ANDROGENIC ALOPECIA
Women with female pattern hair loss have higher levels of certain androgens, suggesting increased androgen exposure to hair follicles.

research Morphogenetic Mechanisms in the Cyclic Regeneration of Hair Follicles and Deer Antlers from Stem Cells
Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.
research Adolescent acne: association to sex, puberty, testosterone and dihydrotestosterone
Higher DHT levels are linked to more acne in adolescents, especially boys.
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Association of ACE2, Insulin Resistance, and Other Parameters in Obese Polycystic Ovary Syndrome Patients Infected with COVID-19
PCOS women with COVID-19 have higher cardiometabolic risks.
research Sexual dimorphism of COVID-19 inspires drug repositioning and host-targeting immunotherapy for viral pneumonia
Balancing testosterone may reduce COVID-19 severity.
research Measurement of Steroid Hormones in Hair: an Analysis of Hormone Dynamics in Hair Follicles
The method accurately measures steroid hormones in hair to study hormone dynamics related to hair loss.
research Determination of some sex hormones in health supplements by liquid chromatography with tandem mass spectrometry
The method detected sex hormones in some health supplements, with one containing banned testosterone.
research Androgen deprivation therapy and hormonal status in men with COVID-19
Hormonal status from androgen deprivation therapy may affect COVID-19 severity in men.
research The role of testosterone in SARS-CoV-2 infection
Low testosterone levels may lead to more severe COVID-19 outcomes.
research Factors Driving Unique Urination Phenotypes of Male and Female 9-week-old C57BL/6J Mice
Testosterone significantly affects urination differences between male and female mice.
research Hormones and Absence Epilepsy☆
Stress and hormones like progesterone can affect absence seizures, but their effects change with different life stages.
research Highly Sensitive Simultaneous Measurement of Steroid Hormone in Human Serum by Liquid Chromatography-electrospray Ionization Tandem Mass Spectrometry
