Key takeaways

Cervical ripening is a natural process that prepares the cervix for labour. When additional support is needed, mechanical or pharmacological methods may be used. Mechanical methods such as DILAPAN-S offer a drug-free approach that works gradually while allowing women to remain mobile during the process.

  • Cervical ripening can begin naturally in the days or weeks before labour.
  • Assisted cervical ripening may be recommended when labour induction is needed and the cervix is not yet ready.
  • Pharmacological methods use medication, while mechanical methods such as DILAPAN-S work without medication.

Getting ready to meet your baby? Cervical ripening is a big part of the final stretch! If your doctor mentioned it and you're curious, dive into this little guide we prepared for you to break it down simply.

What is cervical ripening?

Cervical ripening softens and thins your cervix (the opening to your womb) to help it open for childbirth. It usually happens naturally in the days or weeks leading up to labour. However, if your body needs a little help getting ready, your doctor might recommend a safe method to assist this process.

Why it matters

When the cervix isn’t soft or open enough, labour can take longer or feel harder. Ripening helps your body prepare, making the process smoother and easier for both you and your baby.

When a little extra help might be needed

Every pregnancy is unique, and your healthcare provider will always consider what’s best for you and your baby. In some cases, they may suggest gentle support with cervical ripening—for example, if:

  • Your due date has passed.
  • Your water has broken, but contractions haven’t started yet.
  • There are health reasons why it may be safer to encourage labour.

Remember, these are just examples, and your doctor or midwife will guide you through your options with your well-being in mind.

Two main methods: drug vs. mechanical

There are two ways to help your cervix get ready for labour. Here’s a quick look at each:

Pharmacological methods

  • These contain medications that soften and ripen your cervix.
  • Based on clinical evidence, they can sometimes cause less predictable and more painful contractions, requiring monitoring.

Mechanical methods

  • Mechanical methods, like DILAPAN-S, gently encourage your cervix to soften and open while allowing you to move, rest, and stay as comfortable as possible.
  • They content no medications and their mode of action is purely mechanical, promoting natural processes in your body. Thank to this, they can offer a more natural-like, gentle and predictable experience.

Why choose mechanical methods?

If you’re looking for a non-hormonal approach, DILAPAN-S offers a reliable option. It’s a small device made from patented synthetic material – hydrogel that works by gently expanding, helping your cervix open.

Mechanical methods benefits:

  • Hormone-free.
  • Gentle and predictable.
  • Fits into many birth plans, including natural ones.
  • Allows you to stay mobile during the process, making it more comfortable.

Here’s how the process works, step by step:

  1. Getting started: Your doctor will carefully place the device. The procedure is quick and may cause some discomfort or mild pain, but it doesn’t last long.
  2. Letting it work: The device gently expands over a 12-24 hours, helping your body prepare naturally.
  3. Keeping an eye on things: Your healthcare team will check in to make sure everything is going smoothly.
  4. Ready to go: The device is carefuly removed, your cervix checked and if ready, labour can begin—either on its own or with a little help.

How to prepare

Here are a few tips to make the experience smoother:

  • Ask away: Don’t hesitate to ask your doctor any questions you have.
  • Share your wishes: Let your healthcare team know about your birth plan and preferences.
  • Bring support: Having someone you trust by your side can make all the difference.

Your birth, your way

Every birth is unique. Knowing your options helps you feel more confident and in control. Your healthcare team will be there to support you every step of the way.

FAQs
What Is DILAPAN-S?

‍DILAPAN-S is a synthetic osmotic cervical dilator used to soften and dilate the cervix. It's a non-hormonal method used, among others, to prepare the cervix for labour induction. Multiple national clinical guidelines, including NICE, recommend this non-hormonal approach.

Who may be offered DILAPAN-S for cervical ripening?

DILAPAN-S may be suitable for a wide range of women, including first-time mothers, women with post-term pregnancies and some women planning a vaginal birth after caesarean section (VBAC/TOLAC). Ask your healthcare provider whether DILAPAN-S could be an option for you.

Do I need to stay at the hospital for the cervical ripening period?

Not always—because DILAPAN-S is a drug-free method, outpatient cervical ripening may be an option for you. You can rest, sleep in your own bed, and come back the next day. Your midwife or physician will let you know whether this is right for you (and what to keep in mind while you wait at home).
