research The Neurosteroidogenic Enzyme 5α-Reductase Mediates Psychotic-Like Complications of Sleep Deprivation
This study found that acute sleep deprivation enhanced 5α-reductase expression and activity in the rat prefrontal cortex, and finasteride treatment reduced associated psychosis- and mania-like behaviors.
research Steroidogenesis in steroid related cancers
This study suggests that the adrenal gland may contribute to prostate cancer treatment resistance and indicates potential steroid production or dependency in ovarian cancer.
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.
research Hormonal status of male reproductive system: androgens and estrogens in the testis and epididymis. In vivo and in vitro approaches.
This article summarizes findings on the role of androgens and estrogens in male reproductive tissues across species, highlighting the roles of hormone metabolism, receptor distribution, and stress-induced changes.
research ENHANCEMENT OF FOLLICULAR DELIVERY OF FINASTERIDE IN NIOSOMALAND PRONIOSOMAL GEL FORM FOR TREATING ANDROGENETIC ALOPECIA
This study found that a proniosomal gel formulation of finasteride increased anagen hair count in male volunteers with androgenic alopecia by 42.85% compared to the control group.
research Use of high dose cyproterone acetate and risk of intracranial meningioma in women: cohort study
This study found a strong dose-related increase in the risk of intracranial meningiomas associated with high doses of cyproterone acetate, with some reduction in risk after stopping the treatment.
research Women Also Use 5α-Reductase Inhibitors
This letter to the editor states that the titles of two recent pieces in JAMA Internal Medicine should have included "in Men.
research Steroidogenesis inhibitors alter but do not eliminate androgen synthesis mechanisms during progression to castration-resistance in LNCaP prostate xenografts
This study found that despite the presence of steroidogenesis inhibitors, CRPC tumor cells adapt to continue synthesizing androgens, suggesting a need for more effective androgen axis targeting.
research Effect of finasteride on the ovulatory function of normal women
In this pilot study, finasteride increased testosterone/dihydrotestosterone and progesterone/dihydroprogesterone ratios in normal ovulatory women but did not alter ovulation or gonadotropin secretion.
research <i>In-Vitro</i> Effect of Sex Steroids on Mouse Melanoma (B16F10) Cell Growth
Sex steroids, especially progesterone, can slow down the growth of mouse melanoma cells.
research Women's midlife health Reframing menopause
This review examines menopause's endocrinology, treatment history, and associated changes, noting key issues for midwife management but reports no new clinical results.
research [Studies on androsterone and dehydroepiandrosterone levels in hair under endogenic and exogenic stress].
research Sequential estrogen-progestin addition to gonadotropin-releasing hormone agonist suppression for the chronic treatment of ovarian hyperandrogenism: a pilot study.
This study concluded that a regimen of transdermal estradiol and oral medroxyprogesterone acetate effectively reduces hirsutism while minimizing side effects in women with polycystic ovary syndrome.
research Foreword
This study reports that incomplete information in a reverse supply chain can lead to efficiency losses, but a two-part tariff contract for the remanufacturer may improve performance by eliciting private information from collectors.
research Meibomian Gland Dysfunction: Endocrine Aspects
This study found that increased serum testosterone and dehydroepiandrosterone sulphate levels may serve as diagnostic markers for seborrheic meibomian gland dysfunction in both genders.
research Anabolic-androgenic steroids. Mechanism of action and clinical effects
This study provides a comprehensive analysis of anabolic-androgenic steroids, reporting that their use enhances muscle mass but is associated with significant health issues including cardiac muscle hypertrophy, liver disease, and changes in gender characteristics, emphasizing the need for patient awareness of these risks.
research Studies on Neurosteroids XXV. Influence of a 5.ALPHA.-Reductase Inhibitor, Finasteride, on Rat Brain Neurosteroid Levels and Metabolism
In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.
research [Anti-androgens. Their use in dermatology].
This study found that cyproterone acetate with ethynyl estradiol improved acne and seborrhea within 3–6 months in women, but had less satisfactory results for alopecia and hirsutism.
research ODP021 A Feminizing Adrenocortical Carcinoma Presenting with Marie-Antoinette Syndrome
This case study reports a rare instance of an estradiol-secreting adrenocortical carcinoma in a 58-year-old male, causing feminization and Marie-Antoinette syndrome, with potential paraneoplastic aortitis.
research Regulation of the metabolic phenotype of human hepatocytes by glucocorticoids and androgens
This study found that manipulating 5αR2 activity in human hepatocytes in vitro can regulate lipogenesis, with potential clinical implications for patients taking 5αR inhibitors.
research Sex Steroid Hormones
This study reviews the roles of sex steroid hormones, like estrogens, progestins, and testosterone, in influencing reproductive health and overall well-being, highlighting their impact on conditions such as polycystic ovary syndrome and hypogonadism through their regulation by the hypothalamic-pituitary-gonadal axis.
research Bioidentical Hormone Replacement Therapy at a Hormone Clinic Causing Significant Virilization in a Post-Menopausal Women
This case report highlights the adverse effects of unmonitored bioidentical hormone replacement therapy, emphasizing the need for patient education about its safety and efficacy compared to FDA-regulated hormones.
research In vitro and In vivo Effects of 17β-N-(4-phenylcarbamoyl) androst-4-en-3- one Derivatives as 5a-reductase Inhibitors on Androgen-dependent Glands
In this study, researchers found that steroidal 17β-carboxamides 1-4 significantly inhibited 5α-reductase enzyme activity and reduced prostate weight more effectively than finasteride in a hamster model, without toxic side effects, suggesting potential for treating benign prostatic hyperplasia.
research Biological activity of novel progesterone derivatives having a bulky ester side chains at C-3
This study found that pregnane derivatives with higher lipophilicity, like compound 9d, had stronger androgen receptor binding and greater antiandrogenic effects in rats, correlating relative binding affinity with log P values.
