Testosterone changes reduce thyroxin levels in rats.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research Diagnostic Thresholds for Androgen-Producing Tumors or Pathologic Hyperandrogenism in Women by Use of Total Testosterone Concentrations Measured by Liquid Chromatography-Tandem Mass Spectrometry
Total testosterone levels can help diagnose androgen-producing tumors and hyperandrogenism in women.
research Testosterone modulates vasodilation in mesenteric arteries of hypertensive rats
Testosterone affects blood vessel relaxation in hypertensive rats.
research High circulating oestrone and low testosterone correlate with adverse clinical outcomes in men with advanced liver disease
Men with advanced liver disease and high oestrone and low testosterone levels have worse health outcomes.
research Is semen analysis necessary prior to initiation of finasteride treatment?
research Tanshinone, a Natural NADPH Oxidase Inhibitor, Mitigates Testosterone-Induced Hair Loss
Tanshinone compounds can help prevent hair loss caused by testosterone.
research Male Accessory Sex Glands
Male accessory sex glands in rats rarely develop tumors and respond to hormones.
research Longitudinal association between saliva and hair cortisol concentration: A systematic comparison
Hair cortisol is a reliable marker of long-term cortisol levels and is linked to daytime saliva cortisol but not morning levels.
research Sex differences in COVID-19: the role of androgens in disease severity and progression
Male hormones like testosterone may make COVID-19 worse, and testing for sensitivity to these hormones could help predict how severe a patient's symptoms might be. Treatments that reduce these hormones are being explored.
research Comprehensive transcriptome data to identify downstream genes of testosterone signalling in dermal papilla cells
The research identified genes and non-coding RNAs in cells that could be affected by testosterone, which may help understand hair loss and prostate cancer.
research BH07: Testosterone deficiency in men with female pattern hair loss
Low testosterone levels may contribute to female pattern hair loss in men.
research Sex hormones and sarcopenia in older persons
Sex hormone treatments can increase muscle mass in older adults but have inconsistent effects on muscle function and may carry cardiovascular risks.
research The Utilization of Sex Hormone Antibodies for Screening and Separation of Trace Biological Mixtures
Sex hormone antibodies can help identify male and female contributors in forensic samples.
research Virilization from partner's use of topical androgen in a reproductive-aged woman
A woman's virilization symptoms were caused by her partner's use of testosterone cream, which resolved after they separated.
research Analysis of Methyltestosterone and Testosterone Propionate in Dried Blood Spots After Transdermal Application
The method effectively detects MeT and TP in dried blood spots after cream application.
research Long-Term Suppression of Testosterone After Treatment with a Gonadotropin-Releasing Hormone Agonist in a Woman with a Presumed Testosterone Secreting Ovarian Tumor
The treatment successfully lowered testosterone levels and reduced symptoms.
research 6450 Leydig Cell Tumor: A Rare Cause of Post-menopausal Hyperandrogenism
Leydig cell tumors can cause high testosterone and symptoms in postmenopausal women, and removing them improves symptoms.
research Clinical relevance of testosterone and dihydrotestosterone metabolism in women
Testosterone and dihydrotestosterone play a role in women's health issues like excess hair and baldness, and treatments blocking these hormones may help.
research [Clinical significance of testosterone and dihydrotestosterone metabolism in women].
Antiandrogens and finasteride may help treat excess hair and hair loss in women.
research Mendelian randomization studies of testosterone exposure: A systematic review
Testosterone's health effects are complex and not definitively understood.
research Testicular Steroidogenesis
Genetic defects in testosterone production can cause hormonal and developmental disorders, and more research is needed to understand androgen regulation and develop safer treatments.
research Morphology of the testis and the epididymis in rats with dihydrotestosterone (DHT) deficiency.
DHT deficiency in rats reduces sperm content and affects testis structure over time.
research Safety of testosterone use in women
Short-term testosterone therapy in women seems safe with few mild side effects, but long-term effects need more research.
research Efeitos do tratamento prolongado de testosterona associado ao uso de algestona acetofenida e enantato de estradiol sobre o ciclo menstrual de fêmeas cativas de Sapajus libidinosus (macaco-prego)
The treatment changed hormone levels and increased sexual behavior in female capuchin monkeys.
research Plasma androsterone/epiandrosterone sulfates as markers of 5α-reductase activity: Effect of finasteride in normal men
Finasteride effectively lowers specific hormone levels, helping monitor treatment progress.
research 7452 A Diagnostically Challenging Case of Hyperandrogenism in Postmenopausal Woman
The case highlights the complexity of diagnosing high testosterone in older women and the need for thorough testing.
