,
February 2009 in “Drug Development Research” This article reviews the potential neuroprotective effects of 17α‐estradiol in neurodegenerative diseases and highlights its possibly lower toxicity compared to more feminizing hormones, but it reports no new clinical findings.
2 citations
,
September 1992 in “Steroids” The researchers reported that compounds 11 to 13 derived from Westphalen-type steroids showed strong antiandrogenic activity in vivo, though their effects could not be attributed to 5α-reductase inhibition or androgen receptor binding.
67 citations
,
January 2007 in “Climacteric” This article discusses the impact of estrogens on skin aging, highlighting the potential benefits and unresolved effectiveness of alternatives like phytoestrogens and selective estrogen receptor modulators; it reports no new clinical results.

January 2004 in “European journal of obstetrics, gynecology, and reproductive biology/European journal of obstetrics & gynecology and reproductive biology” This review discusses the use of ethinylestradiol combined with antiandrogenic progestin for treating androgenisation symptoms and improving metabolic and menstrual health in women, but it does not provide new clinical data.
December 2013 in “Estudo Geral (Universidade de Coimbra)” This research investigated the design and synthesis of steroid-based compounds as aromatase inhibitors for breast cancer, finding that certain structural modifications significantly enhance their inhibitory potency.
13 citations
,
January 2005 in “Chemical and Pharmaceutical Bulletin” This study reported that newly synthesized progesterone derivatives significantly reduced prostate weight in testosterone-treated hamsters, with 5alpha-reductase inhibitory activity dependent on the size of the substituent at C-17.
5 citations
,
September 2024 in “Maturitas” In this study, an ultra-low dose combination of estradiol and dydrogesterone significantly reduced hot flushes and improved health-related quality of life among a multi-ethnic population of postmenopausal women, with no notable difference in serious adverse events compared to placebo.
5 citations
,
January 2005 in “Journal of Enzyme Inhibition and Medicinal Chemistry” This study found that certain steroidal compounds, especially 10a–10c, demonstrated strong antiandrogenic activity by binding to the androgen receptor and reducing prostate weight in a hamster model.
78 citations
,
January 2000 in “Gynecological Endocrinology” This study found that the progestins norgestimate and dienogest may help treat clinical hyperandrogeny in women by inhibiting skin 5 alpha-reductase activity with minimal androgenic potential.

19 citations
,
June 1999 in “Steroids” This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.
31 citations
,
September 2020 in “Clinical endocrinology” This review found limited evidence on the effectiveness of different antiandrogens for feminization in transgender women, suggesting cyproterone acetate, leuprolide, and medroxyprogesterone acetate may better suppress testosterone than spironolactone or estradiol alone.
10 citations
,
January 2015 in “Przeglad Menopauzalny” This review discusses the effects and selection criteria of different progestogens in various treatments but reports no direct clinical comparisons of their metabolic effects.
