research Effect of 5α-Dihydrotestosterone and Testosterone on Apoptosis in Human Dermal Papilla Cells
High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.
research Hyperandrogenic eumenorrheic NON-PCOS women versus women with PCOS after the GnRH-agonist stimulation test preceded by suppression of adrenal steroidogenesis with dexamethasone
PCOS women have more severe metabolic issues and higher androgen levels than hyperandrogenic women without PCOS.
research Curcumin derivatives inhibit testicular 17β-hydroxysteroid dehydrogenase 3
Curcumin and its derivatives can block an enzyme important for making testosterone, with one derivative being particularly strong.
research 1 Androgens
Testosterone is made by Leydig cells, is active when not bound to proteins, and works by binding to receptors in muscles and other tissues.
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 Generation of comparative pharmacophoric model for steroidal 5α-reductase I and II inhibitors: A 3D-QSAR study on 6-azasteroids
The study created a model to help design new inhibitors for steroidal 5α-reductase enzymes.
research FRI-02 FROM GIRLS TO BOYS TO OLDER MEN, THE INTERESTING TALE OF THE GUEVEDOCES AND 5-ALPHA REDUCTASE INHIBITORS
The discovery of 5α-reductase deficiency in guevedoces led to the development of important urologic medications.
research Palmitoylethanolamide Stimulation Induces Allopregnanolone Synthesis in C6 Cells and Primary Astrocytes: Involvement of Peroxisome-Proliferator Activated Receptor-α
PEA boosts allopregnanolone production and reduces oxidative stress in brain cells.
research The stimulation of hair growth in the flank organs of female hamsters by subcutaneous testosterone propionate and its inhibition by topical cyproterone acetate: dose-response studies
Testosterone increases hamster hair growth; cyproterone acetate reduces it.
research Serum androgens and risk of atrial fibrillation in older men: The Cardiovascular Health Study
Older men with low levels of a testosterone byproduct had a higher chance of developing an irregular heartbeat.
research Daily subcutaneous testosterone for management of testosterone deficiency
Daily subcutaneous testosterone effectively restores testosterone levels in men.
research Dihydrotestosterone inhibits hair growth in mice by inhibiting insulin-like growth factor-I production in dermal papillae
Dihydrotestosterone (DHT) stops hair growth in mice by lowering a growth factor important for hair.
research Effects of Androgen Treatment on Growth in Patients with 5-α-Reductase Type 2 Deficiency
Androgen treatment with dihydrotestosterone may help maintain height in patients with 5-α-reductase type 2 deficiency, especially before puberty.
research Nuclear and cytosol Androgen Receptor in Androgen Dependent Dermatoses in Female Patients
Nuclear AR levels give better insight into hormone effects in skin conditions.
research Structure of human steroid 5α-reductase 2 with the anti-androgen drug finasteride
Finasteride irreversibly affects human steroid 5α-reductase 2, providing insight into its catalytic mechanism and disease-related mutations.
