Hegar's sign

From Wikipedia, the free encyclopedia

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 possibility to compress the connection between the cervix and the fundus.[1] The uterine fundus is palpable.

The sign is usually present from 4–6 weeks[1] 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.[2]
