Epigenetic Safety of Assisted Reproductive Technology

August 21, 2019 updated by: Dan Zhang, Women's Hospital School Of Medicine Zhejiang University

Epigenetic Safety of Various Protocols in Assisted Reproductive Technology

The primary purpose of the study is to investigate the relationship between different protocols of assisted reproductive technology and the epigenetic safety of the offspring. Different interventions of assisted reproductive technology include controlled ovarian hyperstimulation (COH), in vitro embryo culture, in vitro fertilization(IVF), intracytoplasmic sperm injection(ICSI), frozen-thawed embryo transfer(FET), preimplantation genetic testing(PGT). The investigators are also interested in the relationship between pregnancy outcomes in ART or natural conception and environmental, nutritional and lifestyle factors.

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.

Ages Eligible for Study

20 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

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
birth weight
Time Frame: 1 day after delivery
Weight of newborns at delivery.
1 day after delivery
implantation rate
Time Frame: 11-12 weeks after embryo transfer
Implantation rate was defined as the percentage of fetal heart beat among total transferred embryos at 12 weeks' gestational age.
11-12 weeks after embryo transfer
clinical pregnancy rate
Time Frame: 6 weeks after embryo transfer
Clinical pregnancy was defined as an observation of gestational sac via ultrasonography.
6 weeks after embryo transfer
live birth rate
Time Frame: 1 day after delivery
Number of women with live births / number of women randomized to the specific group.Live birth is defined as the delivery of any viable infant at 28 weeks or more of gestation after our interventions.
1 day after delivery
congenital anomalies rate
Time Frame: 1 day after delivery
Congenital anomaly included deformity and development abnormality of any organs or systems.

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: 28 gestational weeks to 37 gestational weeks
preterm birth is defined as gestational weeks between 28 to 37.
28 gestational weeks to 37 gestational weeks
