A review published in 2020 looked at the effects of dates on labor and delivery. For example, the researchers found that eating dates may reduce the period of the active phase of labor. That’s when the cervix, or the lowermost part of the uterus, dilates from six to 10 millimeters. During labor, the cervix dilates or expands, allowing the fetus to pass through the vagina.
Dates may improve the Bishop score, which measures how ready the cervix is for labor. In contrast, the researchers noted that dates do not affect the length of the rest of the labor or the frequency of C-sections.
