Warts in pregnancy and childbirth...

Sometimes gential warts get larger during pregnancy, making it difficult to urinate.

If the warts are in the vagina, they can make the vagina less elastic and cause obstruction during child birth.

Rarely, infants born to women with genital warts develop warts in their throats (laryngeal papillomatosis). Although uncommon, it is a potentially life-threatening condition for the child, requiring frequent laser surgery to prevent obstruction of the breathing passages. Research on the use of interferon therapy in combination with laser surgery indicates that this drug may show promise in slowing the course of the disease.
