Key requirements

  • Women only
  • Healthy volunteers accepted
  • Adult

Study population: In this study we want to conduct measurements of physiological data as well as hormonal and ultrasound measurements of growing follicles/ ovulation in a group of endocrinologically healthy women with a regular cycle, who aim for a spontaneous pregnancy. We choose these women to generate reliable data on changes of the measured physiological parameters in a healthy menstrual cycle, as well as to evaluate physiological changes associated with the initiation of pregnancy. We want to continue measurements in all pregnancies beginning during the study period to evaluate how the same nine physiological parameters are changing during pregnancy, how strong the variations of the parameters during pregnancy are, and whether they could be associated with early onsets of pregnancy complications such as premature birth or preeclampsia. This will be highly valuable to develop study protocols for the specific evaluation of the screening potential of one of the pregnancy complications.

Who may be able to join

  • women aged 20-40 years
  • regular menstrual cycle (28 days+/-)
  • no hormonal therapy
  • German-speaking
  • written informed consent to participate in the study

Who cannot join

  • any health-related issues that may affect menstrual cycle
  • any consumption of medication or other substances that may affect the menstrual cycle or any of the physiological parameters investigated
  • frequent travel between time zones
  • sleeping disorders
  • unsuccessfully trying to conceive for > 12 months

About this study

In this study physiological data is measured using wearable sensors as well as hormonal and ultrasound measurements of growing follicles/ ovulation in a group of endocrinologically healthy women with regular cycles, who aim for a spontaneous pregnancy. These women were recruited to generate reliable data on changes of the measured physiological parameters in a healthy menstrual cycle, as well as to evaluate physiological changes associated with early pregnancy.

All pregnancies beginning during the study period are to be monitored to their natural end, in order to evaluate how the same nine physiological parameters are changing during pregnancy, how strong the variations of the parameters during pregnancy are, and whether they could be associated with early onsets of pregnancy complications such as premature birth or pre-eclampsia. This will be highly valuable to develop study protocols for the specific evaluation of the screening potential of pregnancy complications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation between the physiology and the menstrual cycle dynamics

    Correlation between a the following physiological parameters (individually or in combination), pulse rate, respiration, skin conductance response, sleep duration and quality, and skin perfusion with the menstrual cycle dynamics

    Measured: November 2016 - November 2020

Secondary outcomes (2)
  1. Correlation between the physiology measured using a wearable device and the occurrence of pregnancy

    Correlation between the following physiological parameters (individually or in combination), pulse rate, respiration, skin conductance response, sleep duration and quality, and skin perfusion with the occurrence of pregnancy.

    Measured: November 2016 - November 2020

  2. Correlation between physiology and pregnancy complications

    Measured: November 2016 - November 2020

Questions about this trial

What is this clinical trial studying?

An observational study of Fertility Disorders and Early Pregnancy, run by University of Zurich at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation between the physiology and the menstrual cycle dynamics (time frame: November 2016 - November 2020). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2022.
