What does the term "latency phase" refer to in labor?

The term "latency phase" in labor refers to the early phase of labor prior to active labor. During this initial stage, the body begins the process of cervical dilation and effacement, but contractions are typically irregular and not strong enough to be classified as active labor. This phase can last several hours or even days, and while it may involve some discomfort, it is characterized by a slower progression of labor compared to the more intense and regular contractions that mark the subsequent active labor phase.

Understanding this phase is important for healthcare providers to properly assess the progress of labor and provide appropriate support to the laboring individual. Recognizing the latency phase also helps in managing expectations regarding the onset of more active labor and allows for preparation for the more intense stages ahead.
