Trial summary

Transabdominal ultrasound guidance is the golden standard for embryo transfers. Transvaginal ultrasound guidance was proposed recently to provide better visualization and reduce patient discomfort as embryo transfer can be performed with an empty bladder in this case. Read more about this study

About this study

Transabdominal ultrasound guidance is the golden standard for embryo transfers. Transvaginal ultrasound guidance was proposed recently to provide better visualization and reduce patient discomfort as embryo transfer can be performed with an empty bladder in this case. The purpose of this study is to determine whether there are any differences between transvaginal and transabdominal ultrasound-guided embryo transfer in terms of ease of use, patient satisfaction, and treatment outcome.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transvaginal ultrasound-guided embryo transferProcedure or surgery

    Also called Kitazato Long ET catheter (Kitazato Medical Co. Ltd., Tokyo, Japan)

    Embryo transfer of two day-3 embryos performed with the Kitazato Long ET catheter (Kitazato Medical Co. Ltd., Tokyo, Japan), guided by transvaginal ultrasound

  • Transabdominal ultrasound-guided embryo transferProcedure or surgery

    Also called Cook Soft-Trans ET catheter (Cook Medical Inc., Bloomington, IN, USA)

    Embryo transfer of two day-3 embryos performed with the Cook Soft-Trans ET catheter (Cook Medical Inc., Bloomington, IN, USA), guided by transabdominal ultrasound

What is being measured

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

  1. Pregnancy rate

    Proportion of patients with a positive pregnancy test

    Measured: At performing the pregnancy test 11 days post-embryo transfer

Secondary outcomes (8)
  1. Clinical pregnancy rate

    Proportion of patients with at least one gestational sac at first pregnancy ultrasound

    Measured: At first pregnancy ultrasound (3 weeks post-embryo transfer)

  2. Ongoing pregnancy rate

    Proportion of patients with at least one live intrauterine fetus at 10 weeks post-embryo transfer

    Measured: At 10 weeks post-embryo transfer

  3. Menstruation-like pain

    Measured on a three-level scale (none/mild/strong)

    Measured: At embryo transfer

  4. Discomfort related to vesical distension

    Measured on a three-level scale (none/mild/strong)

    Measured: At embryo transfer

  5. Overall discomfort

    Measured on a three-level scale (none/mild/strong)

    Measured: At embryo transfer

  6. Difficulty using the assigned technique faced by operators

    Measured on a three-level scale (easy/moderately difficult/very difficult)

    Measured: At embryo transfer

  7. Catheterization time

    Measured: At embryo transfer

  8. Conversion to the opposite technique

    Proportion of cases in which embryo transfer was performed using the technique of the opposite randomization arm (i.e., proportion of patients randomized to have transabdominal ultrasound-guided transfer in whom transvaginal ultrasound-guided was performed, and the other way around)

    Measured: At embryo transfer

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Transvaginal ultrasound-guided embryo transfer and Transabdominal ultrasound-guided embryo transfer in people with Infertility, run by IVI Madrid at 1 site in Spain.

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 1 inclusion and 3 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: stopped early, as of the sponsor's last update on 7 Mar 2017. 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 Spain. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: slow recruitment rate). Results are not available in the source record.

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?

Pregnancy rate (time frame: At performing the pregnancy test 11 days post-embryo transfer). 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 Mar 2017; AzTrials last refreshed its copy on 7 Nov 2026.
