30 / 1000+ results research Analysis of Methyltestosterone and Testosterone Propionate in Dried Blood Spots After Transdermal Application
The method effectively detects MeT and TP in dried blood spots after cream application.
research Evaluation of the rodent Hershberger assay using three reference endocrine disrupters (androgen and antiandrogens)
The assay effectively detects hormonal activity of certain chemicals.
research Testosterone-stimulated weanlings as an alternative to castrated male rats in the Hershberger anti-androgen assay
Using testosterone-stimulated weanling rats can effectively replace castrated rats for anti-androgen testing, reducing animal stress.
research Novel progestogenic androgens for male contraception: design, synthesis, and activity of C7 α-substituted testosterone
New testosterone analogs show promise for male contraception with better activity and potentially fewer side effects.
research Prostate-Sparing Effects in Primates of the Potent Androgen 7α-Methyl-19-Nortestosterone: A Potential Alternative to Testosterone for Androgen Replacement and Male Contraception1
MENT could be a better option than testosterone for male hormone therapy and birth control because it works well at lower doses and has fewer side effects on the prostate.
research Effects of Intramuscular Testosterone Undecanoate on Body Composition and Bone Mineral Density in Female-to-Male Transsexuals
Testosterone undecanoate increases lean mass and causes various physical changes in female-to-male transsexuals.
research Epitestosterone
Epitestosterone may counteract testosterone's effects and has roles in body processes like prostate growth and hair distribution.
research Anabolic effects of testosterone are preserved during inhibition of 5α-reductase
Testosterone can build muscle and bone without enlarging the prostate when a specific enzyme is blocked.
research 17α-Acetoxy-6-bromo-16β-methylpregna-4,6-diene-3,20-dione
A new compound with strong antiandrogenic effects was found, potentially useful for treating conditions like acne and prostate cancer.
research New Synthesis of Methyl 3β-Hydroxy-5-androstene-17β-carboxylate
A new method was developed to make a compound used in finasteride and epristeride with a 69% yield.
research Transmasculine Hormone Therapy
Testosterone therapy for transmasculine individuals is generally safe with medical supervision, improves mental health, and has mixed effects on physical health.
research A Randomized Double-Blind Placebo-Controlled Pilot Trial on the Effects of Testosterone Undecanoate Plus Dutasteride or Placebo on Muscle Strength, Body Composition, and Metabolic Profile in Transmen
Testosterone with dutasteride improves muscle strength and body composition in trans men.
research Testosterone metabolite nonessential for androgen effects
The body's change of testosterone into DHT is not necessary for testosterone's muscle and sexual effects.
research Epitestosterone—an endogenous antiandrogen?
Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.
research Finasteride/testosterone
research Sex-Chromosome-Related Dimorphism in Steroidogenic Enzymes and Androgen Receptor in Response to Testosterone Treatment: An In Vitro Study on Human Primary Skeletal Muscle Cells
Chromosomal differences affect how muscle cells respond to testosterone.
research Reproductive and Nonreproductive Actions of Testosterone
Testosterone is important for male sexual traits, reproduction, muscle and bone health, blood production, and metabolism, and works both directly and after being changed into other hormones.
research Compounded Testosterone Troches TO OPTIMIZE HEALTH AND THE TESTOSTERONE CONTROVERSY.
Properly administered testosterone therapy is safe and effective but often not covered by insurance.
research Epigenetic Effects of Gender-Affirming Hormone Treatment: A Pilot Study of the ESR2 Promoter’s Methylation in AFAB People
Testosterone treatment may change estrogen receptor methylation in AFAB individuals.
research Preparation of3H-labelled testosterone metabolites
The conclusion is that tritium-labeled testosterone metabolites can be made and are better converted into dihydrotestosterone in skin cells than in prostate tissue.
research New Progesterone Esters as 5.ALPHA.-Reductase Inhibitors.
Some new progesterone derivatives are better at blocking testosterone conversion than a common drug.
research The Antiandrogenic Action of 4–Androsten–3–one–17β– Carboxylic Acid and Its Methyl Ester on Hamster Flank Organ1
The chemicals 17βC and its methyl ester can block the effects of testosterone on hamster skin but not the effects of DHT.
research The use of testosterone after menopause
Testosterone therapy can improve sexual satisfaction and mood in surgically menopausal women when used with estrogen, but its long-term safety and effects on naturally menopausal and premenopausal women are unclear.
research Megestrol Acetate Increases the Proliferation, Migration, and Adipogenic Differentiation of Adipose-Derived Stem Cells via Glucocorticoid Receptor
Megestrol acetate helps fat-derived stem cells grow, move, and turn into fat cells through a specific receptor.
research 115 EXOGENOUS TESTOSTERONE ALONE OR WITH FINASTERIDE INCREASES PHYSICAL PERFORMANCE, GRIP STRENGTH, AND LEAN BODY MASS IN OLDER MEN WITH LOW SERUM TESTOSTERONE
Testosterone therapy improves strength and body composition in older men with low testosterone.
research Testosterone therapy for transgender men
Testosterone therapy in transgender men has both desired effects like increased muscle mass and potential health risks such as higher cardiovascular risk.
research Mechanisms of testosterone action
Testosterone works in different ways, including direct interaction with its receptor, conversion to other hormones for specific effects on genitalia, hair, bones, and muscle, and changes in body fat and sexual function when low.
research Advances in male hormone substitution therapy
New treatments for low male hormones improved sexual function and mood but had unclear risks, especially for older men.
research Pharmacokinetics of 2 Novel Formulations of Modified-Release Oral Testosterone Alone and With Finasteride in Normal Men With Experimental Hypogonadism
New oral testosterone formulations show potential for safer, effective hormone replacement in men with low testosterone.
