Embryo Aneuploidies and Morphokinetics in Ovarian Stimulated and Non Stimulated IVF Cycles (AMOS)

July 21, 2020 updated by: Instituto Valenciano de Infertilidad, IVI VALENCIA

Embryo Aneuploidies and Morphokinetics in Ovarian Stimulated and Non Stimulated Cycles. An Intrapatient Comparison Using Next Generation Sequencing in Biopsy of Blastocysts and Time Lapse Evaluation.

The purpose of this study is to compare the number of euploid embryos obtained per metaphase II oocyte in unstimulated (modified natural cycles) and stimulated IVF cycles.

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Effects of ovarian stimulation on human embryo quality is still a subject of study. When natural and stimulated cycles have been compared, no differences have been observed in terms of embryo cleavage capacity, oocyte and embryo aneuploidy rate or incidence of aneuploidy in aborted foetuses. When mild and conventional doses of gonadotropins have been compared, a higher proportion of good morphological quality embryos are observed in the former. On the contrary, we showed that ovarian stimulation does not increase significantly the embryo aneuploidy rate in IVF derived human embryos when unstimulated and stimulated cycles were compared in oocyte donors. In this study, we want to compare the embryo aneuploidy rate between unstimulated and stimulated cycles in infertile patients, subjected to both IVF cycles with blastocyst biopsy and NGS-PGS. A comparison of the morphokinetics will also be performed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Natural Cycle
The patient will not undergo hyperstimulation rather a natural cycle
Stimulated Cycle
The 80 patients will undergo hyperstimulation cycle as per the clinical practice planned for the patient.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of the number of euploid embryos from Metaphase II oocytes in different cohorts of embryos.
Time Frame: 30 days
Number of metaphase II oocyte per euploid embryo in unstimulated and stimulated cycles.
30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of embryo aneuploidies in two cohorts of embryos.
Time Frame: 30 days
Incidence of embryo aneuploidies between the unstimulated and stimulated cycle in the same patient
30 days
Morphokinetic evaluation of embryos in two different cohorts of embryos.
Time Frame: 30 days
Morphokinetic evaluation of the embryos obtained in an unstimulated and stimulated cycle
30 days

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 21, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
April 7, 2020

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
