Measuring cervical stiffness -
A 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. Fortunately, they are mostly harmless. But the symptoms should always be assessed by a specialist, because for the health of mother and child it is important to recognise the few critical cases as early as possible.
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
A measuring device for the Cervical Stiffness
Until now, cervical stiffness could only be determined by vaginal palpation with the fingers and the associated subjective assessment. With the Pregnolia System, a reliable device is now available that can measure the stiffness precisely and quantitatively.
The Pregnolia measurement supports the assessment of premature birth risk:
safe for you and your baby
less intrusive and more hygienic than palpation
The "SoftCervix" study at 12 Swiss hospitals is investigating whether cervical insufficiency can be detected earlier. For this purpose, the stiffness and length of the cervix are
measured in the 5th month. The stiffness is determined with the Pregnolia measuring device. This examination is supplemented by two ultrasound measurements.

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.
