Uterine Dysfunction: Ineffective uterine contractions can fail to dilate the cervix adequately. Fetal Malposition: Abnormal positioning of the fetus, such as occiput posterior, can impede progress. Cephalopelvic Disproportion (CPD): A mismatch between the size of the babyâs head and the motherâs pelvis. Anomalies in the birth canal or maternal pelvis that restrict the passage of the fetus. Maternal Fatigue or psychological stress can also contribute to ineffective labor.
