Venereal warts are caused by the human papilloma virus (HPV), which is passed during intercourse. Venereal warts are skin tags or warts that are transmitted by sexual contact. They are called condylomata acuminatum.
Venereal warts may cause a problem during pregnancy, but usually don't. These warty skin tags can become enlarged during pregnancy. If a woman has extensive veneral warts, a Cesarean delivery may be necessary to avoid heavy bleeding and other complications. Infants delivered through a birth canal infected with venereal warts have been known to get small benign tumors on the vocal cords (laryngeal papillomas) after delivery.
Venereal warts usually aren't treated during pregnancy. If warts become large enough to interfere with delivery, your physician may recommend removing them. If the warts must be removed, excision is the only treatment used during pregnancy.
