research Quantitative analysis of 34 sex (pro)hormones, conjugates and bioactive oxidation products thereof in human plasma by GC- and LC-MS/MS and systematic investigation of overestimations of analyte concentrations not accounted for by method validation
The method accurately measures sex hormones in human plasma but can have small errors.
research A preliminary study of the effect of 11a-hydroxyprogesterone on the hair growth in men suffering from androgenetic alopecia.
The treatment helped promote hair growth in men with androgenetic alopecia.
research Hyperandrogenism, Elevated 17-Hydroxyprogesterone and Its Urinary Metabolites in a Young Woman with Ovarian Steroid Cell Tumor, Not Otherwise Specified: Case Report and Review of the Literature
A young woman's symptoms suggested PCOS, but tests and surgery confirmed and treated a rare ovarian tumor, resolving her condition.
research Pharmacological Profile of 9,11-Dehydrocortexolone 17α-Butyrate (CB-03-04), a New Androgen Antagonist with Antigonadotropic Activity
CB-03-04 shows promise as a treatment for prostate issues due to its strong anti-androgen effects.
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 Allopregnanolone and Induction of Endogenous Opioid Inhibition of Oxytocin Responses to Immune Stress in Pregnant Rats
Allopregnanolone helps control oxytocin levels during pregnancy to prevent preterm labor.
research Pharmacology of different progestogens: the special case of drospirenone
Drospirenone is a unique progestin with anti-water retention and potential blood pressure benefits, used in birth control and hormone therapy.
research Clinical and metabolic effects of medroxyprogesterone acetate and ethinyl estradiol plus drospirenone in women with polycystic ovary syndrome
MPA improved hormonal imbalances and acne in women with PCOS without affecting metabolism.
research A Prospective Study of the Prevalence of Nonclassical Congenital Adrenal Hyperplasia among Women Presenting with Hyperandrogenic Symptoms and Signs
About 2.2% of women with symptoms of high male hormones have a mild form of congenital adrenal hyperplasia, and measuring a specific hormone level can accurately diagnose it.
research The First Syntheses of 16β-Chloro- and 16β-Bromo-cyproterone Acetate
Scientists made two new chemicals that might help treat diseases caused by male hormones.
research Comparison of resumption of ovulation after cessation of oral contraceptives and medroxyprogesterone acetate in women with polycystic ovary syndrome
Medroxyprogesterone acetate is as effective as oral contraceptives for resuming ovulation in women with PCOS.
research Effects of halogenated analogues of cortisol and progesterone upon hair growth in castrated mice.
Certain chemical changes to cortisol and progesterone can increase or decrease their ability to inhibit hair growth.
research Neuroactive Steroids: Functions, Mechanisms of Action and Physiologic Relevance
Allopregnanolone may enhance alcohol's effects on dopamine neurons, influencing addiction risk.
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.
research PROGRESSIVE SLEEP APNOEAS RESPOND TO MEDROXYPROGESTERONE ACETATE
Medroxyprogesterone acetate improved sleep apnea symptoms in some obese patients.
research Affect of a six months treatment regiment of metformin (MET) on 17-hydroxyprogesterone (17P) responses to GnRH agonist (GnRH Ag) in polycystic ovary syndrome (PCOS)
Metformin can start ovulation and may lower 17P response in PCOS, but six months is too short to improve hair growth or change body fat distribution.
research Respiratory regulation by steroids in newborn rats: a sex‐specific balance between allopregnanolone and progesterone receptors
Breathing in newborn rats is affected differently by hormones based on their sex.
research Decreased allopregnanolone induced by hormonal contraceptives is associated with a reduction in social behavior and sexual motivation in female rats
Hormonal contraceptives may reduce social behavior and sexual motivation by lowering allopregnanolone levels.
research The anxiolytic effect of pregnancy in rats is reversed by finasteride
Pregnancy reduces anxiety in rats, but finasteride reverses this effect.
research [Proliferation behavior of the anagen hair bulb in androgenetic alopecia before and after local administration of 17 alpha- propylmesterolone–DNA flow cytophotometry studies].
Topical 17 alpha-propylmesterolone increases hair cell growth in androgenetic alopecia.
research Central Opioid Inhibition of Neuroendocrine Stress Responses in Pregnancy in the Rat Is Induced by the Neurosteroid Allopregnanolone
