research Remarks on the Hormonal Background of the Male Equivalent of Polycystic Ovary Syndrome
Men might have a version of the female disease, polycystic ovarian syndrome, shown by changes in hormone levels and early baldness, but more research is needed to fully understand it.
research GhDET2, a steroid 5α‐reductase, plays an important role in cotton fiber cell initiation and elongation
GhDET2 is crucial for cotton fiber growth.
research Acne
Hormonal treatments can help with acne, especially in women, by lowering androgen levels or blocking their effects.
research Matriptase activation and shedding with HAI-1 is induced by steroid sex hormones in human prostate cancer cells, but not in breast cancer cells
Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.
research Protective cardiovascular and renal actions of vitamin D and estrogen
Vitamin D and estrogen may help protect heart and kidney health, and maintaining sufficient vitamin D levels could be especially beneficial for African Americans, postmenopausal women, and people with chronic kidney disease.
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 SAT-223 Insights into Ovarian Hyperandrogenism: Lessons from Two Unusual Cases
The study found that imaging might miss small ovarian tumors causing high testosterone, and suggested using certain testosterone levels and treatment responses to identify these tumors.
research New steps forward in the neuroactive steroid field
Neuroactive steroids could become safe, effective treatments with more understanding of their complex brain actions and metabolism.
research Indirect clinical markers for the detection of anabolic steroid abuse beyond the conventional doping control in athletes
New signs like changes in blood markers, physical symptoms, and behavioral shifts may help detect hidden steroid use in athletes.
research Untargeted Metabolomics and Steroid Signatures in Urine of Male Pattern Baldness Patients after Finasteride Treatment for a Year
Finasteride treatment changes urine metabolomics and steroid signatures, potentially monitoring effectiveness but may cause sexual side effects.
research Simultaneous Determination of Selected Steroids with Neuroactive Effects in Human Serum by Ultrahigh-Performance Liquid Chromatography–Tandem Mass Spectrometry
