research Testosterone and doping control
The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.
research Epitestosterone
Epitestosterone may counteract testosterone's effects and has roles in body processes like prostate growth and hair distribution.
research Optimization of LC method for the determination of testosterone and epitestosterone in urine samples in view of biomedical studies and anti-doping research studies
Researchers developed a reliable method to measure testosterone and epitestosterone in urine for medical and anti-doping use.
research Biochemical Roles of Testosterone and Epitestosterone to 5α-Reductase as Indicators of Male-Pattern Baldness
High testosterone to epitestosterone ratio in hair could predict male-pattern baldness.
research Doping-Control Analysis of the 5α-Reductase Inhibitor Finasteride: Determination of Its Influence on Urinary Steroid Profiles and Detection of Its Major Urinary Metabolite
Finasteride affects urinary steroid profiles and can potentially hide steroid abuse in sports drug testing.
research Influence of Saw palmetto and Pygeum africana extracts on the urinary concentrations of endogenous anabolic steroids: Relevance to doping analysis
Taking Saw palmetto and Pygeum africana can change the levels of certain steroids in urine, which could cause confusion in doping tests.
research Testosterone-like immunoreactivity in hair measured in minute sample amounts - a competitive radioimmunoassay with an adequate limit of detection
The new test can measure very small amounts of testosterone in hair, and grinding the hair up first gives more accurate results.
research Untargeted Metabolomics and Steroid Signatures in Urine of Male Pattern Baldness Patients after Finasteride Treatment for a Year
Finasteride treatment changes urine metabolomics and steroid signatures, potentially monitoring effectiveness but may cause sexual side effects.
research Male gonadal function in coeliac disease: 2. Sex hormones.
Men with coeliac disease may have hormone imbalances that could affect sexual function, but these can improve with better gut health.
research Gender Differences in Skin Aging and the Changing Profile of the Sex Hormones with Age
The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.
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 Liquid Chromatography-Mass Spectrometry-Based In Vitro Metabolic Profiling Reveals Altered Enzyme Expressions in Eicosanoid Metabolism
The method reliably profiles eicosanoids and shows epitestosterone reduces their levels, similar to common anti-inflammatory drugs.
research Simultaneous determination of androgens and prostaglandins in human urine using ultra-high-performance liquid chromatography–tandem mass spectrometry
Researchers developed a reliable way to measure hormones in urine, showing that a baldness treatment doesn't change hormone levels.
research Prostate-Specific Antigen as a Marker of Hyperandrogenism in Women and Its Implications for Antidoping
PSA levels could help detect illegal steroid use in female athletes but face challenges like cost and PCOS prevalence.
research Plasmaproteinbindung endogener Glucocorticosteroide und deren Einfluss auf Haar- und Speichelkonzentrationen
Plasma protein binding significantly affects glucocorticosteroid concentration in blood, saliva, and hair.
research Clinical biochemistry of dihydrotestosterone
Understanding how DHT works is important for diagnosing and treating hormone-related disorders.
research Does a male polycystic ovarian syndrome equivalent exist?
Early onset baldness in men may indicate a condition similar to PCOS, linked to heart disease, diabetes, and prostate issues.
research Female Hirsutism: Pathophysiological Considerations and Therapeutic Implications*
Excessive hair growth in women often has no known cause and is not linked to race or other hormonal symptoms.
research Enzyme-linked immunosorbent assays for doping control of 5α-reductase inhibitors finasteride and dutasteride
New tests detect finasteride and dutasteride in urine quickly and easily.
research Serial Hydrolysis for the Simultaneous Analysis of Catecholamines and Steroids in the Urine of Patients with Alopecia Areata
A new method was created to analyze certain chemicals in the urine of alopecia areata patients, revealing they have higher metanephrine content. This method can also be used for other related diseases.
research Androgen antagonists in androgen target tissues
Antiandrogens have important biological effects, but more research is needed to understand them fully and compare their effectiveness and side effects to other treatments.
research Pharmacology of anabolic steroids
Anabolic steroids can build muscle and strength but have risks and need more research on their clinical benefits and side effects.
research High resolution full scan liquid chromatography mass spectrometry comprehensive screening in sports antidoping urine analysis
The method effectively detects banned substances in urine for sports antidoping.
research Persistent erectile dysfunction in men exposed to the 5α-reductase inhibitors, finasteride, or dutasteride
Using finasteride or dutasteride may cause long-lasting erectile dysfunction.
research Long-term physiological trends and their drivers: linking hair hormone concentrations with telemetry data in GPS-collared Serengeti wildebeest
Wildebeest stress and hormone levels are influenced by food availability, human presence, and reproductive cycles.
research Review of the effects of 17α-estradiol in humans: a less feminizing estrogen with neuroprotective potential
17α-estradiol is a safe estrogen that might protect the brain and doesn't cause feminization, needing more research for treating brain diseases.
research Intracrine androgen biosynthesis, metabolism and action revisited
The document concludes that blocking the internal pathways that create androgens might help treat cancers that depend on sex hormones.
