research Polymorphisms in Androgen and Estrogen Receptor Genes: Effects on Male Aging
Changes in testosterone and estrogen receptor genes can affect how men age, influencing body fat, hair patterns, and possibly leading to skin disorders.
research Inhibitory Effects of Serenoa Repens on the Kinetics of Pig Prostatic Microsomal 5α-Reductase Activity
Saw palmetto extract can block the enzyme that converts testosterone in pig prostate cells.
research Association Between Severity of Depression and Clinico-Biochemical Markers of Polycystic Ovary Syndrome
Depression severity is not linked to PCOS markers like BMI, insulin resistance, or testosterone levels.
research A Case of Androgen-Secreting Adrenal Carcinoma with Non-Classical Congenital Adrenal Hyperplasia
A woman with a rare adrenal tumor and hormonal disorder had improved testosterone levels after surgery, but her menstrual irregularities continued.
research Hyperandrogenism from an Ovarian Interstitial-Cell Tumor in an Alpaca
An alpaca acted like a male and couldn't have babies because of a benign tumor in its ovary that caused high testosterone levels.
research Kinetic Analysis of LY320236: Competitive Inhibitor of Type I and Non-Competitive Inhibitor of Type II Human Steroid 5α-Reductase
LY320236 is a strong blocker of two enzymes that change testosterone into dihydrotestosterone and might help treat conditions related to male hormones.
research Age-Dependent Regulation by Androgens of Gene Expression in the Anterior Hypothalamus and Stress-Induced Release of Adrenal Hormones in Adolescent and Adult Male Rats
Testosterone affects stress hormone levels differently in adolescent and adult male rats.
research Androgens in Women: Critical Evaluation of Methods for Their Determination in Diagnosing Endocrine Disorders
The conclusion is that standardizing testosterone measurement methods is essential for better diagnosis accuracy in women.
research Development of Prostate Cancer in a Patient with Primary Hypogonadism: Intratumoral Steroidogenesis in Prostate Cancer Tissues
Prostate cancer can progress even with low testosterone due to internal hormone production in the tumor.
research Mitochondria Dysfunction and Inflammation in Traumatic Brain Injury: Androgens to the Battlefront
Androgens like testosterone may help treat traumatic brain injury by reducing mitochondrial stress and inflammation.
research Strumal Carcinoid Tumor of the Ovary
A woman's ovarian tumor causing high testosterone was successfully removed, and her symptoms improved.
research Androgen Receptor-Mediated Inhibition of Cutaneous Wound Healing
Blocking testosterone speeds up wound healing in males.
research Effects of the Anti-Androgen Finasteride on 5α-Reduction of Androgens in the Presence of Progesterone in Human Gingival Fibroblasts: Modulatory Actions of the Alkaline Phosphatase Inhibitor Levamisole
Finasteride reduces testosterone conversion, progesterone lessens this, and levamisole enhances finasteride's effect.
research Transcriptomic Profiling in Silurana Tropicalis Testes Exposed to Finasteride
Finasteride affects frog testes by increasing testosterone, decreasing 5α-DHT, and impacting genes related to reproduction and other functions.
research The Differences Between Aromatizable And Non-Aromatizable Androgens In Relation To Body Composition And Metabolic Syndrome Risk Factors In Men
Testosterone and dihydrotestosterone have similar effects on body composition and metabolic health in men.
research 5α-Metabolism in Finasteride-Treated Subjects and Male Pseudohermaphrodites with Inherited 5α-Reductase Deficiency
Finasteride lowers DHT levels and raises testosterone in a dose-dependent way.
research Preponderance of Serum and Intra-Hepatic 5α-Dihydrotestosterone in Males with Hepatocellular Carcinoma Despite Low Circulating Androgen Levels
Men with liver cancer have higher levels of a specific testosterone byproduct in their liver and blood, despite overall lower male hormone levels.
research Hair Loss Among Transgender and Gender-Nonbinary Patients: A Cross-Sectional Study
Transgender and nonbinary individuals experience hair loss, with transmen on testosterone seeing more severe hair loss, while feminizing hormones may stabilize hair loss in transwomen.
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 Pharmacodynamic Modeling of Finasteride, a 5 Alpha-Reductase Inhibitor
Finasteride, a drug that changes testosterone to a different hormone, was studied and its effects over time were modeled successfully.
research A Case of Familial Male-Limited Precocious Puberty with a Novel Mutation
A boy with a rare form of early puberty caused by a new gene mutation responded well to treatment aimed at reducing testosterone and preserving adult height.
research Hormonal Control of Vas Deferens Fluid Volume and Aquaporin Expression in Rats
Testosterone increases fluid secretion and aquaporin expression in the vas deferens, which is important for male fertility.
research Hormonal Evaluation of Hyperandrogenism in Women
The woman's high testosterone levels indicated PCOS, leading to treatment that improved her symptoms.
research Markers of Hyperandrogenism in South Asians with Polycystic Ovary Syndrome
The FG score is better at detecting hyperandrogenism in PCOS patients than testosterone levels or FAI, but testosterone is the recommended test for diagnosis.
research Virilizing Ovarian Tumor in a Woman with an Adrenal Nodule
A woman with high testosterone and an adrenal nodule had an ovarian tumor causing her symptoms, which improved after the tumor was removed.
research Androgens in SARS-CoV-2 Coronavirus Infections
Men, particularly those with hair loss, are more likely to get the virus, and those with prostate cancer may have milder symptoms. Testosterone's role in the disease is unclear, and the virus doesn't seem to harm male fertility. Women with PCOS might be at higher risk. More research is needed.
