Hegar's sign

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.[1]

The sign is usually present from 4–6 weeks[2] 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.[3]
