  Purpose
The purpose of this study is to explore a method to identify the viability of day-3 poor quality embryos

Condition
Infertility

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Availability of Poor Quality Embryos in Frozen-thawed Embryo Transfer Cycles

Further study details as provided by Yang Jie, The Second Affiliated Hospital of Kunming Medical University:

Primary Outcome Measures:
  • pregnancy rate [ Time Frame: 5 weeks ]

Enrollment: 481
Study Start Date: January 2011
Study Completion Date: October 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
day-3 poor quality embryos
developmental stage
day3 poor quality embryos day4 morular day-5/6 blastocyst

Detailed Description:
Day-3 poor quality embryos are related to significant lower clinical pregnancy,so freezing numerous poor quality embryos are clinical impractical. To ensure the successful pregnancy and to enhance the availability of the poor quality embryos, day-3 poor quality embryos are further cultured to different developmental stage and then cryopreserved. The viability of these embryos are tested in frozen-thawed transfer.
