240-270 / 1000+ results research AB032. Development of new treatment modality for male infertility by using phytopharmaceuticals
MOTILIPERM may help treat male infertility by reducing stress in cells.
research Pharmacokinetic and Therapeutic Dose Comparison of Diane-35 and IVF-C Inj 5000 IU in Common Quail
Both steroids, especially cyproterone acetate, harm quail's vital organs.
research 17-Oximino-5-androsten-3β-yl esters: synthesis, antiproliferative activity, acute toxicity, and effect on serum androgen level
Some synthesized compounds were more effective than Finasteride in reducing prostate cancer cell growth and androgen levels.
research Mixture effects of endocrine disrupting compounds in vitro
Weak endocrine disruptors in mixtures can have significant effects and should be considered in risk assessments.
research Pharmacology of antiandrogens
Antiandrogens affect androgen-dependent body functions and are used for various medical conditions, with some risks like fetus feminization, but new forms like 17α-propylmesterolone show promise for acne without systemic effects.
research More about X‐linked testicular feminization of the mouse as a noninducible (is) mutation of a regulatory locus: 5α‐androstan‐3α‐17ß‐diol as the true inducer of kidney alcohol dehydrogenase and ß‐glucuronidase
A specific metabolite, not a receptor protein, triggers the production of certain kidney enzymes, but this process is disrupted in mice with a mutation causing testicular feminization.
research Counterfeit drugs and pharmaceutical preparations seized from the black market among bodybuilders
Many black market drugs for bodybuilders are fake and mislabeled.
research Mechanism of action of bolandiol (19-nortestosterone-3β,17β-diol), a unique anabolic steroid with androgenic, estrogenic, and progestational activities
Bolandiol, a synthetic steroid, builds muscle and bone without greatly affecting sex glands, and works differently from other hormones.
research Testosterone up-regulates vacuolar ATPase expression and functional activities in vas deferens of orchidectomized rats
Testosterone increases acidification in the vas deferens by up-regulating V-ATPase.
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 Progestogens with Antiandrogenic Properties
research An unusual circulating steroid profile in a virilized postmenopausal woman
A 68-year-old woman developed male traits due to a tumor in her ovary, which was removed, returning her hormone levels to normal.
research From bench to babies – drug development for male subfertility
New methods may speed up drug development for male subfertility.
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 A Review of Androgen‐Progestin Regimens for Male Contraception
Hormonal male contraception is effective and could be market-ready, but more research is needed to ensure safety for all ethnic groups.
research Long-term detection of methyltestosterone (ab-) use by a yeast transactivation system
A yeast-based test can detect the steroid methyltestosterone in urine longer than traditional methods.
research Disruptors of Androgen Action and Synthesis
Certain pesticides and fungicides can interfere with male hormone functions, potentially causing reproductive issues in male rats.
research Ausgeprägte Virilisierung in der Postmenopause - eine Falldarstellung
A postmenopausal woman had high testosterone from her right adrenal gland, leading to recommended surgery.
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 A new method for synthesis of finasteride
A new, safer method to make finasteride from progesterone is effective for industrial use.
