Nipple stimulation can induce uterine contractions, which may cause preterm labor or miscarriage if the fetus is not full term, and requires prompt medical attention at the hospital.
Nipple stimulation will cause the release of hysteronin, causing uterine smooth muscle contractions. In late pregnancy by stimulating the nipple can induce contractions, accelerate the progress of labor, more suitable for mothers beyond the pre-pregnancy period to carry out.
Pregnant women who stimulate their nipples will induce contractions, which will lead to risks such as miscarriage and preterm labor if there are frequent contractions, so pregnant mothers should not feel free to stimulate their nipples during pregnancy. If nipple stimulation is needed because of inverted nipples or other problems, it must be done under the guidance of a professional doctor to avoid harming the fetus.
