Definition of Uterine contraction
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Uterine contraction: The tightening and shortening of the uterine muscles.
During labor, contractions accomplish two things: (1) they cause the cervix to thin and dilate (open); and (2) they help the baby to descend into the birth canal.
Uterine contractions also occur during the monthly menstrual cycle and are recognized as menstrual cramps.
