The conversion rate is about 15.76%, almost triple that of Δ4-androstenedione, due to utilization of a different enzymatic pathway. There is also some conversion into estrogen, since testosterone is the metabolic precursor of the estrogens. Δ4-Androstenediol is closer to testosterone structurally than Δ5-androstenediol, and has androgenic effects, acting as a weak partial agonist of the androgen receptor. However, due to its lower intrinsic activity in comparison, in the presence of full agonists like testosterone or dihydrotestosterone (DHT), Δ4-androstenediol has antagonistic actions, behaving more like an antiandrogen.〔 ==Medical and commercial use== Patrick Arnold holds a 1999 patent on "Use of 4-androstenediol to increase testosterone levels in humans".〔http://www.patentstorm.us/patents/5880117/description.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「4-Androstenediol」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
