Genital Warts in Pregnancy: Safe Treatment

Why Warts Can Change in Pregnancy

During pregnancy the immune system adapts and blood flow to the genital area increases, so existing warts can grow or new ones can appear, sometimes more quickly than usual, and occasionally into larger clusters. This is a normal response to pregnancy, not a sign of anything wrong, and it doesn’t mean the infection is more serious. Genital warts are caused by low-risk HPV (types 6 and 11) that don’t cause cancer, and warts often shrink or settle again in the months after delivery as things return to normal.

It’s worth getting any new genital lumps in pregnancy checked to confirm what they are, because a few other things can look similar and reassurance is valuable at this time. Mention them at a routine antenatal appointment, or have them assessed separately. What doesn’t fit simple warts — significant pain, an ulcer, heavy bleeding, or a single firm, rapidly growing or hardened lump — should be looked at promptly rather than assumed to be a wart.

Treat or Wait?

For many women, watchful waiting is the sensible default in pregnancy — because warts frequently improve after birth and there’s no urgency to remove harmless growths while you’re expecting. Treatment is considered when warts are troublesome: uncomfortable, bleeding, growing rapidly, or extensive enough to be a practical concern. The decision is always individual and made together with your maternity team, who know your full picture. Whatever you decide, having the diagnosis confirmed is worthwhile, because a few other things can look like warts.

Which Treatments Are Safe (and Which Aren’t)

• Avoided in pregnancy: the prescription creams podophyllotoxin (Warticon) and imiquimod are not used, as they aren’t considered safe in pregnancy.
• Generally suitable where treatment is needed: physical methods — cryotherapy, or removal by cautery — performed carefully, are the usual choices.
• Watchful waiting: often reasonable, as many warts settle after delivery.

Always tell any clinician you’re pregnant so the plan is adjusted accordingly, and coordinate treatment with your midwife or obstetrician. The methods themselves are described in the complete genital wart removal guide, and the background on the virus in understanding genital warts & HPV.

Your Baby and Birth

This is what most worries expectant parents, and the reassurance is genuine: passing HPV to the baby is very rare, and genital warts usually don’t change how you give birth. A vaginal delivery is normally still possible and appropriate. Caesarean is only rarely indicated — reserved for the uncommon situation where warts are very large and physically obstruct the birth canal. Any such decision is made by your obstetric team, who weigh up your complete circumstances rather than the warts alone.

After the Birth and Breastfeeding

Warts that grew in pregnancy often shrink or clear in the weeks and months after delivery as immunity and blood flow return to normal. If any remain and you’d like them treated, that can be arranged once you’re recovered, using the standard options. Breastfeeding is not affected by genital warts, and if treatment is needed afterwards the method is chosen with any breastfeeding in mind. In short: pregnancy changes the timing and the choice of treatment, not your long-term outlook, which is very good.

Your Questions, Answered

Why have my genital warts got worse in pregnancy?

Pregnancy changes immunity and increases blood flow to the area, so warts can grow or multiply faster than usual. It’s a normal response, not a sign of anything more serious, and they often settle again after the birth.

Can genital warts be treated during pregnancy?

Yes, if needed. The prescription creams podophyllotoxin and imiquimod are avoided, but physical methods like cryotherapy or cautery can be used carefully, coordinated with your maternity team. Often, though, watchful waiting is chosen because warts settle after delivery.

Can I pass HPV or warts to my baby?

Transmission to the baby is very rare. Genital warts usually don’t affect the baby or the birth, and the wart-causing HPV types are low-risk and don’t cause cancer.

Will I need a caesarean because of genital warts?

Almost never. A vaginal delivery is normally still possible. Caesarean is only rarely indicated, for the uncommon case where very large warts physically obstruct the birth canal — a decision made by your obstetric team.

Will the warts go away after I give birth?

Often, yes — warts that grew in pregnancy frequently shrink or clear in the weeks and months afterwards. Any that remain can be treated once you’ve recovered, using the standard options.

Is it safe to have warts treated while breastfeeding?

Breastfeeding isn’t affected by genital warts, and if treatment is needed afterwards, a physical method such as cautery or cryotherapy can be used with your breastfeeding in mind. As always, tell the clinician you’re breastfeeding so the plan is adjusted accordingly.

Should I get new lumps checked during pregnancy?

Yes — it’s worth confirming what any new genital lump is, because a few other things can look similar. Mention it at a routine antenatal appointment or have it assessed separately; the diagnosis is straightforward and usually reassuring.
