Sex steroids, especially progesterone, can slow down the growth of mouse melanoma cells.
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 Steroid 5α-reductases and 3α-hydroxysteroid dehydrogenases: key enzymes in androgen metabolism
Key enzymes control androgen levels, affecting hormone activity and potential treatments.
research [Analysis of steroids and binding proteins in the blood of women with androgenetic alopecia].
Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.
