research Search for New antineoplastic agents based on structural modifications of steroidal 5α-reductase, 17β-hydroxysteroid dehydrogenase, and 17α-hydroxylase/17,20-lyase inhibitors
Modifying steroidal inhibitors shows promise for developing new cancer treatments.
research Androgenic and anti-androgenic effects of progesterone derivatives with different halogens as substituents at the C-6 position
Different halogens on progesterone derivatives can either block or mimic male hormone effects, depending on their type and amount.
research 2-Substituted 4-(Thio)chromenone 6-O-Sulfamates: Potent Inhibitors of Human Steroid Sulfatase
New compounds were made that block an enzyme linked to breast cancer better than existing treatments.
research Molecular Interactions of New Pregnenedione Derivatives
The new progesterone derivatives effectively inhibit 5α-reductase and bind to the androgen receptor.
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 Steroidogenesis of the testis – new genes and pathways
New genes and pathways are important for testosterone production and male sexual development.

The method accurately measures certain steroids in human hair, showing different levels in males and females.
research Effect of finasteride on adrenal steroidogenesis in men.
Finasteride, when taken daily, lowers dihydrotestosterone levels but doesn't noticeably affect adrenal steroid production, except by blocking the 5 alpha-reductase enzyme.

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.
