Effacement
Effacement describes how your cervix thins, softens, and shortens as labor approaches. Before effacement, the cervix is about 3 to 4 centimeters long and firm, like the tip of a nose. As labor nears, it gradually thins out and merges with the lower part of the uterus. This process is measured as a percentage: 0% means no effacement, while 100% means the cervix is fully thinned. Effacement and dilation usually happen together, but in first-time mothers the cervix often effaces before it dilates significantly. Your doctor or midwife will report both numbers together to give a clearer picture of how ready your body is for birth.
What This Means for You
Understanding Effacement is an important part of your labor journey. When preparing for birth, understanding this term helps you discuss your birth preferences with your midwife or OB-GYN and know what to expect in the delivery room.

In Singapore hospitals, effacement is routinely assessed alongside dilation and the baby's station during labor reviews. First-time mothers often experience more effacement before dilation begins, which is completely normal.
