January 2004 This study found that while some extracts from DanGuiBoHyulTangGami-Bang showed potential in inhibiting 5-reductase type Ⅱ and had antioxidant activity, they were not effective in extending the hair growth period.
43 citations
,
November 1975 in “Archives of Dermatology” This review discusses testosterone metabolism in human skin and its link to androgenetic alopecia, acne vulgaris, and idiopathic hirsutism, but it presents no new results.
This study found that testosterone enhances glucose-stimulated insulin secretion in male and female human islets, requiring conversion to DHT and E2 via SRD5A1 and aromatase.
56 citations
,
November 2007 in “Molecular and cellular endocrinology” This study identified enzymes responsible for regulating androgen action in the human prostate, suggesting that inhibiting AKR1C2 or RL-HSD may have therapeutic potential in androgen insufficiency or benign prostatic hyperplasia, respectively.
26 citations
,
September 1999 in “Canadian Journal of Botany” This study found that a recessive mutation in the RHD4 gene of Arabidopsis thaliana leads to slower and more variable tip growth in seedling root hairs, resulting in shorter and wider hairs than in wild-type plants.
3 citations
,
October 2021 in “Clinica Chimica Acta” This study found that higher levels of dihydrotestosterone in the parietal region of the scalp may correlate with the clinical presentation of androgenetic alopecia.
