You might never see your own cervix in your lifetime, but that doesn’t mean you shouldn’t be clued up on all the weird and wonderful things there are to know about it.
With Jo’s Cervical Cancer Trust’s latest survey also finding that almost half of women don’t know what the cervix is – and one in six being unable to name a single function of the cervix – we thought now, during Cervical Screening Awareness Week – was a good time to remind ourselves of all the incredible things you probably didn’t know about your cervix.
1. It’s the neck of your womb
The cervix sits above the vagina and just below the womb and forms the neck of your womb. The word cervix comes from Latin and literally means ‘neck of the womb’ (the womb is also known as the uterus).
2. It produces mucus
Vaginal discharge is not often talked about so you probably don’t know that your cervix produces some of it.
Your cervix produces something called mucus that changes in consistency during your menstrual cycle, these changes are designed to either prevent or encourage pregnancy.
3. It helps menstrual blood to flow
During your period, the cervix opens a small amount to allow blood to flow out from the womb to the vagina.
4. It creates a seal
What is known as a cervical mucus plug forms inside the cervix during pregnancy to protect the womb and baby from any bacteria or viruses. As your body prepares for labour your cervix starts to soften and open up (dilate) slowly releasing the mucus plug.
5. It can open really wide
If you’ve ever watched a movie where a women gives birth you probably heard nurses chatting about something being dilated and that it hasn’t reached 10cm yet. Well, that’s the cervix they’re talking about.
During labour the cervix dilates (open up) to allow the baby to move from the womb to the vagina ready for birth. At the beginning the baby’s head rests on the cervix, but as labour goes on the cervix slowly starts to dilate, soften and shorten. In the end your cervix will be dilated to around 10cm (or more) to allow your baby’s head to move through to the vagina.
6. It can prevent or encourage pregnancy
Your hormone levels change during your menstrual cycle and a higher level of oestrogen makes the mucus produced by your cervix thinner, this allows sperm to pass through to the womb. At other times you have higher level of the hormone progesterone, which will make the mucus thicker and more acidic. This helps to prevent pregnancy.
Sounds impossible, because… well, where can it go?
Usually the cervix sits straight at the top of your womb, potentially leaning forward toward your belly. However, some women have a tilted womb making the cervix lean more towards the back which can make it harder to see during a cervical screening (sometimes called a smear test). Nurses sometimes suggest popping your hands underneath your bottom as this helps to tilt it forward.
8. Your cervix changes with age
Once you go through the menopause your ovaries slowly stop producing the hormones oestrogen and progesterone, which means that your cervix won’t be able to produce as much mucus and this can lead to vaginal dryness.
Vaginal dryness can make cervical screening more uncomfortable so please do speak to your nurse as they may prescribe you a vaginal oestrogen cream or pessary to use before your test which can help to make it more comfortable.
Hormonal changes also mean that the cervix can move higher up.
9. It looks like a doughnut
Yes, you heard that right. It’s thick and round with a hole in the middle. Just like your favourite snack.
