HPV and Pregnancy
How Does HPV Affect the Fetus?There is a very low risk for HPV transmission to the unborn baby during a vaginal delivery. Fortunately, even when the virus is passed, the baby is most often able to get rid of it on its own.
In rare cases, a baby that is exposed to HPV may develop warts in the throat or voice box (known medically as laryngeal papillomatosis). Although uncommon, this is a potentially life-threatening condition for the child, requiring frequent laser surgery to prevent obstruction of the breathing passages. These warts can occur up to five years after birth.
Because of the low risk of transmission, along with the increased risks with surgery (see Cesarean Complications), a C-section delivery is usually not recommended for a woman with an uncomplicated HPV infection.
