Effects of Antioxidant Supplementation of Culture Media on IVF Embryos

Status Completed

Clinical Trial Summary

The goal of this clinical trial is to investigate the impact of repeated antioxidant supplementation on blastocyst utilization and expansion rates in embryos under different oxygen concentrations. The study aims to answer the following main questions: - Does adding antioxidants every 12 hours to embryo culture media improve usable and expanded blastocyst utilization rates on days 5 and 6? - How are the O2 concentrations related to the effect of different methods of antioxidants supplementation on blastocysts utilization and expansion rates? Participants in this study are infertile couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. - Zygotes will be incubated at either 5% or 20% oxygen tension until the blastocyst stage. - Sibling zygotes will be divided into four groups: Group 1A and 1B: Antioxidants every 12 hours at either 5% or 20% O2 tension, respectively. Group 2A and 2B: Antioxidants only once at the beginning of embryo culture at either 5% or 20% O2 tension, respectively. Researchers will compare the four groups to determine if the repeated antioxidant supplementation of the culture media leads to improved blastocyst utilization and expansion rates compared to the baseline group.

Clinical Trial Description

This study is focused on the role of antioxidants (AOXs) in mitigating reactive oxygen species and oxidative stress, which have been associated with failure in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). The research aimed to evaluate the effect of two different methods of antioxidants supplementation at two O2 tensions on blastocyst utilization and expansion rates. To achieve this, 3603 zygotes from infertile couples undergoing IVF or ICSI were included in the study. The zygotes were divided into two groups: Group 1A and 1B: Antioxidants every 12 hours at either 5% or 20% O2 tension, respectively. Group 2A and 2B: Antioxidants only once at the beginning of embryo culture at either 5% or 20% O2 tension, respectively. . ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
