research 11α-Hydroxyprogesterone, a Potent 11β-Hydroxysteroid Dehydrogenase Inhibitor, Is Metabolized by Steroid-5α-Reductase and Cytochrome P450 17α-Hydroxylase/17,20-Lyase to Produce C11α-Derivatives of 21-Deoxycortisol and 11-Hydroxyandrostenedione In Vitro
11α-Hydroxyprogesterone is changed into different substances by certain enzymes and may play a role in prostate cancer.
research Basics of Androgen Synthesis and Action
Androgens like testosterone are important hormones for both men and women, made differently in each sex and affecting the body by regulating genes and quick interactions with cell components.
research The Diagnosis of Nonclassic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency Based on Serum Basal or Post-ACTH Stimulation 17-Hydroxyprogesterone Can Lead to False-Positive Diagnosis
Using 17-hydroxyprogesterone levels to diagnose nonclassic congenital adrenal hyperplasia can result in many incorrect diagnoses.
research Treatment of Hirsutism and Acne with Cyproterone Acetate

research Adrenal 21-Hydroxylase Gene Mutations in Slovenian Hyperandrogenic Women: Evaluation of Corticotrophin Stimulation and HLA Polymorphisms in Screening for Carrier Status
The study concluded that testing hormone levels after stimulation is not reliable for identifying carriers of 21-hydroxylase deficiency; genetic testing is necessary.
research The Laboratory in the Multidisciplinary Diagnosis of Differences or Disorders of Sex Development (DSD)
Diagnosing sex development disorders requires combining medical history, physical exams, imaging, lab tests, and genetic data.
research Role of Androgens in Female-Pattern Androgenetic Alopecia, Either Alone or Associated with Other Symptoms of Hyperandrogenism
Androgens significantly affect female hair loss, and hormonal treatments may help.
research CYP21A2 Genotypes Do Not Predict the Severity of Hyperandrogenic Manifestations in the Nonclassical Form of Congenital Adrenal Hyperplasia
The severity of symptoms in nonclassical congenital adrenal hyperplasia is not determined by CYP21A2 gene variations.
research Management of Endocrine Disease: Hyperandrogenic States in Women - Pitfalls in Laboratory Diagnosis
Diagnosing hyperandrogenism in women is complex and requires accurate testing methods and consideration of SHBG levels.
research Carriers of 21-Hydroxylase Deficiency Are Not at Increased Risk for Hyperandrogenism
People who carry the 21-Hydroxylase Deficiency gene are not more likely to have excessive male hormone levels.
research Hair Corticosterone Measurement in Mouse Models of Type 1 and Type 2 Diabetes Mellitus
New hair growth corticosterone levels are higher in diabetic mice, indicating long-term stress.
research 46,XY DSD Due to Impaired Androgen Production
Impaired androgen production in 46,XY DSDs causes ambiguous genitalia and requires long-term care.
research Hair Cycle and Alopecia X in Dogs
Alopecia X in dogs is a cosmetic issue, not a hormonal disorder, and harmful treatments should be avoided.
research The SAHA Syndrome: Overview and Classification
SAHA syndrome is a condition in women involving skin and hair issues, often related to hormonal imbalances, and is treated based on the underlying cause.
research Hair Cortisol in Sheltered Cows and Its Association with Other Welfare Indicators
High hair cortisol levels indicate stress in cows due to poor shelter conditions and health issues.
research Nonclassic Adrenal Hyperplasia: Clinical Features, Diagnosis, and Treatment
