November 2009 in “Journal of steroid biochemistry and molecular biology/The Journal of steroid biochemistry and molecular biology” This study found that bolandiol increased lean body mass and bone mineral density in castrate adult male rats, exhibiting tissue selectivity and acting through multiple receptor pathways with less potency compared to other androgens.
6 citations
,
June 2006 in “International Journal of Gynecological Pathology” This study reports that in a case of benign Brenner tumor, elevated androgens may originate from luteinized stromal cells, as these cells do not convert androgen to estrogen due to suppressed aromatase biosynthesis.
44 citations
,
March 2004 in “Journal of Investigative Dermatology” This study observed that in vitro treatment of male frontotemporal scalp hair follicles with 17-β-estradiol stimulated hair shaft generation and hair matrix keratinocyte proliferation, suggesting potential anagen-prolonging effects.
15 citations
,
October 2003 in “Annals of Oncology” Hair loss can occur as a side effect of certain breast cancer treatments, but minoxidil can help regrow hair.
In this review, the authors highlight that drugs promoting androgenic activity or inhibiting estrogenic activity may unmask or worsen androgenetic alopecia in genetically predisposed individuals, indicating the need for careful management in clinical settings.
January 2026 in “Journal of Education Health and Sport” This review assesses whether using letrozole alongside physical activity and nutrition is clinically beneficial for enhancing ovulation outcomes in women with PCOS-related infertility, but it doesn't report specific results from the evaluation.
65 citations
,
May 2006 in “Journal of Investigative Dermatology” This study found that dexamethasone significantly reduced ERα mRNA levels and increased aromatase mRNA and activity in cultured human hair follicle dermal papilla cells, suggesting a glucocorticoid-dependent mechanism for estradiol action.
24 citations
,
January 2011 in “Sexual Development” This study observed that chemically-induced intersex frogs displayed altered brain mRNA profiles, with finasteride increasing certain hormone-related gene expressions and fadrozole reducing aromatase activity without affecting gene transcript levels.
This study observed that using only a 5 alpha-reductase inhibitor was ineffective for treating androgen-dependent hair loss in women, possibly due to differing copper levels influencing enzyme activity.
19 citations
,
July 2018 in “Medicines” This review highlights the pharmaceutical potential of secondary metabolites from Juniperus species, noting promising antitumor, antibacterial, and antiviral activities, but reports no new experimental findings.
34 citations
,
December 1991 in “Annals of the New York Academy of Sciences” This study found that while the steroid mechanisms influencing androgenetic alopecia may be similar for men and women, differences in enzyme activity and receptor content could explain their varied clinical presentations.
50 citations
,
December 2006 in “Bone” This study found that the steroidal aromatase inhibitor exemestane stimulated proliferation of human osteoblast cells, suggesting both androgen receptor-dependent and independent pathways are involved.
19 citations
,
May 2013 in “Annals of Oncology” This study observed that aromatase inhibitors caused hair loss in menopausal women with breast cancer, mimicking male pattern baldness rather than female androgenetic alopecia.
100 citations
,
September 2017 in “Molecular and Cellular Endocrinology” This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.
