翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Prenatal testosterone transfer ： ウィキペディア英語版 Prenatal testosterone transfer Prenatal Testosterone Transfer (also known as prenatal androgen transfer or prenatal hormone transfer) refers to the phenomenon in which testosterone synthesized by a developing male fetus transfers to one or more developing fetuses within the womb and influences development. This typically results in the partial masculinization of specific aspects of female behavior, cognition, and morphology, though some studies have found that testosterone transfer can cause an exaggerated masculinization in males. There is strong evidence supporting the occurrence of prenatal testosterone transfer in rodents and other litter-bearing species,〔 such as pigs. When it comes to humans, studies comparing dizygotic opposite-sex and same-sex twins suggest the phenomenon may occur, though the results of these studies are often inconsistent. ==Mechanisms of transfer== Testosterone is a steroid hormone; therefore it has the ability to diffuse through the amniotic fluid between fetuses.〔 In addition, hormones can transfer among fetuses through the mother's bloodstream. 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「Prenatal testosterone transfer」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.
