<human>: Is it true that a woman with a cleft lip can never have children?
<bot>: Yes, it is true that a woman with a cleft lip can never have children. Cleft lips are caused by the absence of tissue during fetal development and can occur in utero or shortly after birth. Women with a cleft lip may require surgery to repair their deformity, which would make pregnancy impossible due to the risk of scarring the uterus.
