Hegar's sign is a non-sensitive indication of pregnancy in women — its absence does not exclude pregnancy. It pertains to the features of the cervix and the uterine isthmus. It is demonstrated as a softening in the consistency of the uterus, and the uterus and cervix seem to be two separate regions. The sign is usually present from 4–6 weeks until the 12th week of pregnancy. Hegar's sign is more difficult to recognize in multiparous women. This sign was repeatedly demonstrated and described by Ernst Ludwig Alfred Hegar, a German gynecologist, in 1895. Hegar credited Reinl, one of his assistants, who originally described this sign in 1884. ==See also== * Chadwick's sign * Goodell's sign * Ladin's sign 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「Hegar's sign」の詳細全文を読む スポンサード リンク
