Comparing embryos from different conception methods

Ambispective Comparative Cohort Study to Assess the Differences in Development and Growth Patterns of Biopsied and Non-Biopsied ICSI Embryos and Natural Pregnancy Embryos[BNB-ICSI Study]

Observational Wael Elbanna Clinic · NCT04280757

This study looks at how embryos created through different methods, including a special sperm injection and natural conception, grow and develop to see if taking a small sample from them affects their progress.

What this trial studies

This observational study compares the growth and biochemical parameters of embryos conceived through intracytoplasmic sperm injection (ICSI) with and without preimplantation genetic screening (PGS) to those from natural pregnancies. It aims to determine if biopsying embryos affects their development and to analyze prenatal biochemical parameters across these groups. The study will collect and review medical records from participants and will involve blood tests and ultrasounds to gather relevant data. Participants will be grouped into three arms: biopsied ICSI embryos, non-biopsied ICSI embryos, and naturally conceived embryos.

Who should consider this trial

Good fit: Ideal candidates are singleton pregnant women aged 20 to 40 who are non-smokers and have a BMI between 19 and 40.

Not a fit: Patients with systemic diseases, uterine abnormalities, or confirmed hematological and immunological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effects of genetic screening on embryo development, potentially improving assisted reproductive techniques.

How similar studies have performed: While the approach of comparing biopsied and non-biopsied embryos is gaining interest, this specific comparative analysis is relatively novel and has not been extensively tested in prior studies.
