A new method accurately measures nine steroid hormones in human serum with high sensitivity.
research Hyperandrogenic eumenorrheic NON-PCOS women versus women with PCOS after the GnRH-agonist stimulation test preceded by suppression of adrenal steroidogenesis with dexamethasone
PCOS women have more severe metabolic issues and higher androgen levels than hyperandrogenic women without PCOS.
research New Aromatic Esters of Progesterone as Antiandrogens
New progesterone-based compounds can block male hormones.
research Validation of hair estradiol immuno-assays across the menstrual cycle in emerging adults

research 6 Peripheral androgens and the role of androstanediol glucuronide
Androstanediol glucuronide is a reliable marker for hirsutism in women.
research Inhibition of skin 5α-reductase by oral contraceptive progestinsin vitro
Norgestimate is the most effective birth control progestin for reducing an enzyme linked to acne and excessive hair growth in women.
research Decreased allopregnanolone induced by hormonal contraceptives is associated with a reduction in social behavior and sexual motivation in female rats
Hormonal contraceptives may reduce social behavior and sexual motivation by lowering allopregnanolone levels.
research Progestogens with Antiandrogenic Properties
research Antiandrogen Treatment with Spironolactone and Linestrenol Decreases Bone Mineral Density in Eumenorrhoeic Women with Androgen Excess
Taking spironolactone and linestrenol for androgen excess can lead to lower bone density in young women.

Polymers increased skin permeation and stability of steroid hormones in liposomal formulations.
research Effects of depot medroxyprogesterone acetate, the copper IUD and the levonorgestrel implant on testosterone, sex hormone binding globulin and free testosterone levels: ancillary study of the ECHO randomized clinical trial
The levonorgestrel implant increases free testosterone and lowers SHBG more than DMPA-IM and the copper IUD.
research The role of estrogen in cutaneous ageing and repair
Estrogen helps improve skin aging and healing, especially in post-menopausal women.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
