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 Epitestosterone—An Endogenous Antiandrogen?
Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.
research Optimization of LC Method for the Determination of Testosterone and Epitestosterone in Urine Samples for Biomedical and Anti-Doping Research
Researchers developed a reliable method to measure testosterone and epitestosterone in urine for medical and anti-doping use.
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 Testosterone and Doping Control
The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.
research Hormonal Profile of Men with Premature Balding
Men with early balding often have hormone levels similar to women with polycystic ovary syndrome.
research Effects of Subchronic Finasteride Treatment and Withdrawal on Neuroactive Steroid Levels and Their Receptors in the Male Rat Brain
Finasteride treatment changes brain steroid levels and receptors, affecting brain function even after stopping treatment.
research Hair Steroid Profiling Reveals Racial Differences in Male Pattern Baldness Between Korean and Caucasian Populations
Korean and Caucasian men with male pattern baldness have different hair steroid levels.
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 Male Gonadal Function in Coeliac Disease: Sex Hormones
Men with coeliac disease may have hormone imbalances that could affect sexual function, but these can improve with better gut health.
research Androgen Binding Profiles of Two Distinct Nuclear Androgen Receptors in Atlantic Croaker (Micropogonias Undulatus)
Different types of androgens bind differently to two receptors, AR1 and AR2, in Atlantic croaker's brain and ovarian tissues, suggesting these receptors may control different androgen actions in fish.
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 Persistent Erectile Dysfunction in Men Exposed to 5α-Reductase Inhibitors, Finasteride, or Dutasteride
Using finasteride or dutasteride may cause long-lasting erectile dysfunction.
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 Evidence-Based Approach to Cutaneous Hyperandrogenism in Women
The conclusion is that oral contraceptives and antiandrogens can treat hirsutism and acne in women with cutaneous hyperandrogenism, but more research is needed for effective treatments, especially for hair loss.
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 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 Revisiting Hyper- and Hypo-Androgenism by Tandem Mass Spectrometry
The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.
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 Allopregnanolone Promotes Proliferation and Differential Gene Expression in Human Glioblastoma Cells
Allopregnanolone increases growth and changes gene activity in human brain cancer cells.
research Evaluation of Androgens in the Scalp Hair and Plasma of Patients with Male-Pattern Baldness Before and After Finasteride Administration
Finasteride lowers scalp and blood DHT levels, potentially treating male-pattern baldness.
research The Androgen Receptor and Its Use in Biological Assays: Looking Toward Effect-Based Testing and Its Applications
Scientists have developed a new method to detect steroid abuse in athletes using cell-based tests, which could be the future of anti-doping methods.
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 Dihydrotestosterone Induces p27 Degradation via Direct Binding with SKP2 in Ovarian and Breast Cancer
Dihydrotestosterone causes p27 protein breakdown in ovarian and breast cancer cells by binding with SKP2.
research Forensics in Dermatology: Part II
Dermatologists play a key role in identifying and documenting signs of abuse and injury for forensic investigations.
