Trial summary

Factors affecting the success of the treatment of infertility can evaluate before and after embryo transfer in two stages. Most of the patients reach the embryo transfer stage. Unfortunately, the investigators are able to intervene very few of the factors that will affect the success of the post-transfer. Read more about this study

About this study

Official title: A Comparative Analysis of Ovarian, Uterine and Spiral Arterial Blood Flow in Unexplained Infertility, Tubal Infertility and Fertile Groups

Factors affecting the success of the treatment of infertility can evaluate before and after embryo transfer in two stages. Most of the patients reach the embryo transfer stage. Unfortunately, the investigators are able to intervene very few of the factors that will affect the success of the post-transfer. All factors and treatments that affect the implantation is vital to identify. Basically, healthy vasculature is essential for a successful implantation. The investigators will try to understand relationship between vascular resistance and type of infertility. The investigators will examine whether the effect of the ovarian uterine and spiral artery resistance over infertility.

Read the detailed description

In this study the investigators will examine whether the alterations of doppler indices in the uterine, ovarian and spiral arteries can help to explain tubal or unexplained infertility as a standard screening method. Patients in unexplained-tubal infertility groups were treated in our IVF clinic. Patients will be invited to the hospital according to the criteria of the study. Fertile patients will be selected according to the criteria for patients who have come for the annual smear control. The study hypothesis is that the resistance in ovarian, uterine and spiral artery doppler will be higher in cases with tubal and unexplained infertility as opposed to low resistance in fertile women.Ovarian, uterine and spiral artery pulsatility index (PI = (peak systolic velocity - end diastolic velocity) / time averaged velocity and resistance index ( RI= (peak systolic velocity - end diastolic velocity) / peak systolic velocity ) will measure with doppler ultrasonography in the mid-luteal phase ( 21th day). Measured values are to be compared.

What is being measured

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

  1. The primary outcome measure of this study is to evaluate the possible difference in ovarian artery impedance to blood flow ( RI and PI) among unexplained infertility, tubal infertility and fertile group.

    Measured: 2-3 month

  2. The primary outcome measure of this study is to evaluate the possible difference in uterine artery impedance to blood flow (RI and PI) among unexplained infertility, tubal infertility and fertile group.

    Measured: 2-3 month

  3. The primary outcome measure of this study is to evaluate the possible difference in spiral artery impedance to blood flow ( RI and PI) among unexplained infertility, tubal infertility and fertile group.

    Measured: 2-3 month

Questions about this trial

What is this clinical trial studying?

An observational study of Infertility, run by Suleymaniye Birth And Women's Health Education And Research Hospital at 1 site in Turkey (Türkiye).

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 4 inclusion and 2 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 7 Jul 2015. 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 Turkey (Türkiye). 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?

The primary outcome measure of this study is to evaluate the possible difference in ovarian artery impedance to blood flow ( RI and PI) among unexplained infertility, tubal infertility and fertile group. (time frame: 2-3 month). The study lists 3 primary outcomes in all. 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 7 Jul 2015.
