Antiandrogens have important biological effects, but more research is needed to understand them fully and compare their effectiveness and side effects to other treatments.
research A rational approach to the diagnosis of polycystic ovarian syndrome during adolescence
Diagnosing PCOS in teenagers should focus on signs of excess male hormones and not rely solely on ovarian ultrasound or irregular periods, and should be reassessed in adulthood.
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 Hair Growth Activity of Crataegus pinnatifida on C57BL/6 Mouse Model
