Analyzing hair with this method can help understand and monitor scalp conditions and treatment effects.
research Dehydroepiandrosterone (DHEA) and Testosterone Concentrations in Human Hair after Chronic DHEA Supplementation

Young girls whose mothers have PCOS may have higher activity of a specific enzyme that could lead to developing PCOS later.
research Steroid Sulfatase Deficiency and Androgen Activation Before and After Puberty
In STSD patients, the body compensates for low androgen levels by increasing another enzyme's activity.
research C19and C215β/5αMetabolite Ratios in Subjects Treated with the 5α-Reductase Inhibitor Finasteride: Comparison of Male Pseudohermaphrodites with Inherited 5α-Reductase Deficiency*

Korean women's hair thins, weakens, and greys with age, with mineral and sterol changes.
research Hirsutism, its pathogenesis
Hirsutism in females is caused by high male hormones or sensitive hair follicles.

Two teenage brothers had a rare, treatment-resistant form of female-pattern hair loss with unusual scalp changes.
research 5α-Reductase inhibitors alter steroid metabolism and may contribute to insulin resistance, diabetes, metabolic syndrome and vascular disease: a medical hypothesis
Some hair loss and prostate drugs might increase the risk of diabetes and heart disease.
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 11α-Hydroxyprogesterone, a potent 11β-hydroxysteroid dehydrogenase inhibitor, is metabolised by steroid-5α-reductase and cytochrome P450 17α-hydroxylase/17,20-lyase to produce C11α-derivatives of 21-deoxycortisol and 11-hydroxyandrostenedione in vitro
11α-Hydroxyprogesterone is changed into different substances by certain enzymes and may play a role in prostate cancer.
research Relationship Between Steroid Hormones and Metabolic Profile in Women With Polycystic Ovary Syndrome
Overweight women with PCOS have higher levels of certain hormones that could indicate a higher risk of heart and metabolic problems.
research Total testosterone to dihydrotestosterone ratio assessed by LC-MS/MS predicts a worse metabolic profile not only in PCOS patients
A higher testosterone to dihydrotestosterone ratio may indicate worse metabolic health in women.
research Hyperandrogenism, Elevated 17-Hydroxyprogesterone and Its Urinary Metabolites in a Young Woman with Ovarian Steroid Cell Tumor, Not Otherwise Specified: Case Report and Review of the Literature
A young woman's symptoms suggested PCOS, but tests and surgery confirmed and treated a rare ovarian tumor, resolving her condition.
research Effects of mitotane treatment on human steroid metabolism: implications for patient management
Mitotane changes steroid breakdown, affecting cortisol availability.
research In-vivo uptake and metabolism of testosterone by the skin and other tissues of the rat
Rat skin takes up and processes testosterone differently than other organs, with testosterone being more important for the skin than its metabolite 5α-DHT.
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 Gender-specific alteration of steroid metabolism and its impact on viral replication in a mouse model of hepatitis B virus infection
Hepatitis B virus alters steroid hormones in male mice, reducing dihydrotestosterone to inhibit viral replication.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Stress and alcohol affect brain chemicals differently in rats, mice, and humans, influenced by genetic differences.
research Ovine placental steroid synthesis and metabolism in late gestation†
Diet changes hormone levels in pregnant ewes by affecting metabolism, not placental synthesis.
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 Calcineurin-based immunosuppression in renal transplantation : focus on efficacy, the role of steroids, and the cardiovascular risk
Tacrolimus causes fewer acute rejections than cyclosporin A in kidney transplants but doesn't necessarily improve kidney function after one year; cardiovascular risks and side effects vary between the two drugs.
