Hegar sign

Softening of the lower part of the uterus, felt by the examiner in early pregnancy.

HAY-gar SINE noun

What it means

During a pelvic exam, the narrow lower part of the uterus (the isthmus) feels softer than usual, often from about 6 to 8 weeks of pregnancy. It is a probable sign of pregnancy, because other things can cause it too. It is named after Alfred Hegar, a German gynecologist of the late 1800s.
