World first in pregnancy care
Many pregnancies are accompanied by certain symptoms: a pulling sensation in the abdomen, abdominal pain or downward pressure. Especially in early pregnancy, these can be worrying symptoms - associated with concerns or even fears of a premature birth. Pregnolia gives professionals a new tool to detect critical cases early or to reassure the expectant mothers - the measurement of cervical stiffness.
Contact the centres that already use the Pregnolia System or ask your trusted doctor.
The ETH spin-off Pregnolia is taking an innovative step into the future with its measuring device for the stiffness of the cervix. Pregnolia provides gynaecologists with a new device for prenatal care  and gives pregnant women a safe feeling for a healthy pregnancy. Current studies also give hope for effective, early detection of premature births .
in the pregnancy care
Until now, gynaecologists have been faced with a mystery: half of premature births occur quite suddenly without any prior symptoms or causes . One of the reasons for a premature birth can be a cervical insufficiency. Softer cervical tissue or shortening can be signs of an impending premature birth . Therefore, the condition of the cervix is examined during pregnancy. Pregnolia now makes it possible to measure cervical stiffness with an uncomplicated procedure - a world first in prenatal diagnostics .
The following health insurances cover the examination through their supplementary insurances:
myFlex Outpatient Insurance
Supplementary insurance Classic, Family, Jump
For all self-paying women, the examination costs 150 - 200 CHF
the cervix softens
before it shortens
During pregnancy, the cervix becomes softer and shorter. Eventually, the cervix will open completely at birth . A very soft cervix can be a sign of an impending premature birth.
A clinical study by ETH Zurich and the University Hospital Zurich has shown that the cervix first softens during pregnancy and only then shortens . This means that the Pregnolia System can identify a change in the cervix earlier than an ultrasound exam may detect a change in length. This is possible only with an objective and sensitive measurement device like the Pregnolia System, which is much more precise than the subjective method of palpation .

Questions and answers about Preventive examination with the Pregnolia System
Why should I have cervical stiffness determined?The determination of cervical stiffness provides additional information about the cervix and supports the assessment of the risk of premature birth.
Does my baby feel anything from the cervical measurement?No, the baby does not feel anything from the measurement. The determination of cervical stiffness is gentle, localised and does not require ultrasound waves .
Is the examination with the Pregnolia System suitable for me?The Pregnolia measurement can be carried out in most pregnancies during a regular pregnancy examination.
Who covers the costs of the examination?The supplementary outpatient insurances of CSS, Helsana and Sanitas cover the examination with the Pregnolia measuring device. For all self-paying women, the examination costs 150-200 CHF.
In which week of pregnancy (GW) can the measurement be taken, at the earliest?It makes most sense to take a measurement from the 18th gestational week (GW).
What possible symptoms of premature birth should I make an appointment with my gynaecologist for?Always! Symptoms can be: Abdominal pain, pulling in the abdomen, downward pressure, spotting, leakage of fluid, or a “here we go” feeling.
Which screening examinations are usually carried out or are part of the standard?The following examinations are frequently carried out: General condition, disorders, ultrasound, vaginal examination, swab tests, blood/urine examinations, blood pressure, pulse, weight check, fundal status/abdominal girth, fetal heart tones, fetal movements, oedema, varicose veins, and prenatal tests.
When is a child a premature baby?A pregnancy lasts about 40 weeks. Children who are born before the 37th week are considered premature babies . In Switzerland, this is every 15th child . Premature babies are often too light and too small and need medical support to maintain their circulation .
What can I do if my gynaecologist does not yet have the Pregnolia device?Talk to her/him! Download the brochure for your next consultation here. Your doctor can contact us at any time.
What is there to consider specifically for the measurement of cervical stiffness in a high-risk pregnancy?The measurement can also be performed in high-risk pregnancies. If there is a risk (e.g., high/very young maternal age, twins, IVF, previous premature births, diabetes, previous caesarean sections, miscarriages, etc.) the pregnant woman is monitored closely, and more measurements of cervical stiffness may also be useful, for example.
What are the chances of survival in the case of premature birth and how can the risk be reduced?The prognosis usually depends on the week of pregnancy in which the child is born. The later in pregnancy a premature birth occurs and the heavier the child is, the better its chances of survival . The earlier a risk can be identified, the earlier the risk of premature birth can be treated.
What measures are taken if the results of the measurement of cervical stiffness indicate a soft cervix?Your gynaecologist will discuss the best measures with you. These could be, for example: magnesium, bryophyllum, progesterone, physical rest, or pessary, etc.
