How can kissing cause early labor?

Answer 1

Kissing cannot cause a woman to go into early labor. Even French kissing cannot force a woman into labor. Instead, changes in hormone levels begin several weeks before the first labor contractions. Many women experience Braxton-Hicks contractions, often called "false labor" for up to 2 to 3 weeks before real labor begins. During those last few weeks, the baby should turn head down, and begin to move toward the birth canal. That pressure helps to begin the dilation (opening) of the cervix so that many women are already 1-2 cm dilated when they arrive at the hospital. Sexual intercourse during the last couple weeks can in some cases start true labor; your doctor will advise you about whether you should have intercourse.
