Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The culturing human embryo in vitro is a process of myriad contributing elements. From these factors is the pH of embryo culture media, which is crucial for embryo development. The investigators plan to examine three different pH values of the culture media on the live birth rate of in vitro cultured human embryos.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In vitro fertilisation laboratory is the black box in which early human embryo development of infertile couple occurs. This laboratory holds many variables such as incubator type, air quality, brands of culture media, culture temperature and the pH of culture medium. Despite the importance of the culture medium pH, there is no single RCT has examined its effect on live birth rate post in vitro fertilisation. The investigators of this study believe that leaving this crucial element to the wishes of large companies and media designers is unwise. This RCT aims to provide a conclusive answer on pH effect on live birth rate of in vitro cultured human embryos.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transfer embryos from 7.20±0.02 pH

In this arm, the intervention is to culture the inseminated oocytes in vitro in a pH of 7.2±0.02 from day 0 to 5/6 post IVF/ICSI. Then according to the result of the randomization, women will receive their embryos that will be cultured in this pH on either Day 3 or Day 5/6 post IVF/ICSI.

Group Type EXPERIMENTAL

Transfer embryo from pH 7.20±0.02 on either Day 3 or day 5/6

Intervention Type OTHER

Post IVF/ICSI and according to the result of the randomization process, women will receive embryo from their oocytes that will be cultured in pH of 7.20±0.02.

Transfer embryos from 7.3±0.02 pH

In this arm, the intervention is to culture the inseminated oocytes in vitro in a pH of 7.3±0.02 from day 0 to 5/6 post IVF/ICSI. Then according to the result of the randomization, women will receive their embryos that will be cultured in this pH on either Day 3 or Day 5/6 post IVF/ICSI.

Group Type EXPERIMENTAL

Transfer embryo from pH 7.3±0.02 either Day 3 or day 5/6

Intervention Type OTHER

Post IVF/ICSI and according to the result of the randomization process, women will receive embryo from their oocytes that will be cultured in pH of 7.3±0.02.

Transfer embryo from 7.4±0.02

In this arm, the intervention is to culture the inseminated oocytes in vitro in a pH of 7.4±0.02 from day 0 to 5/6 post IVF/ICSI. Then according to the result of the randomization, women will receive their embryos that will be cultured in this pH on either Day 3 or Day 5/6 post IVF/ICSI.

Group Type EXPERIMENTAL

Transfer embryo from pH of 7.4±0.02 on either Day 3 or day 5/6

Intervention Type OTHER

Post IVF/ICSI and according to the result of the randomization process, women will receive embryo from their oocytes that will be cultured in pH of 7.4±0.02 from day 0 to 5/6
