Comparison of Human Embryo Development Using Sequential and Single Media With Time-lapse Imaging

Not Applicable

Completed

• Conditions: Infertility

• Registration Number: NCT01939626
• Lead Sponsor: Vitrolife

Brief Summary

The purpose of this study is to compare human embryo in vitro development in sequential and single-step culture medium using time-lapse imaging.

Detailed Description

Objective: To study whether a culture medium that allows undisturbed culture supports human embryo development to the blastocyst stage equivalently to a well-established sequential media.

Design: Randomized, double-blinded sibling trial. Setting: Independent in vitro fertilization (IVF) clinics. Patient(s): One hundred twenty-eight patients, with 1,356 zygotes randomized into two study arms.

Intervention(s): Embryos from each patient were randomly allocated into two study arms to compare embryo development on a time-lapse system using a single-step medium or sequential media.

Primary Outcome Measures

Name	Time	Method
Percentage of good quality blastocysts	5 days of in vitro embryo culture	A cohort of human embryos will be divided into two different media. The ability of the media to support human embryo development will be determined using the standard assessment of the percentage of embryos that achieve a defined embryo grade.

Secondary Outcome Measures

Name	Time	Method
% GQE DAY 3	Measured 3 days after oocyte pick-up	Percentage of good quality embryos on day 3 of development
Blast. rate	Measured 5 and 6 days after oocyte pick-up.	Number of embryos reaching the blastocyts stage on either day 5 or day 6.
Blast. Utilization rate	Measured 5 and 6 days after oocyte pick-up	Number of blastocyst that are cryopreserved or transfered on either day 5 or 6 of embryo development.
