Brief summary

A Prospective cohort study including couples with poor responder females who undergoing ICSI

Detailed description

Purpose: To determine the optimal embryonic stage for transfer in poor responders. Method: Patients were divided into day 3 transfer group and day 5 transfer group. All cases had the same stimulation protocol and planning to do fresh embryo transfer. Assessments will be at Day 1, Day 3 and Day 5/6 according to Gardner's criteria 1999. Embryological and clinical data were recorded and then analyzed using SPSS (version 23) statistical software.

Interventions

OTHERCleavage stage transfer

transferring embryos through ICSI procedures for poor responders on cleavage stage of embryonic development.

OTHERBlast stage transfer

transferring embryos through ICSI procedures for poor responders on blast stage of embryonic development.

Design outcomes

Primary

MeasureTime frameDescription
Live birth ratedelivery of healthy neonate after 37 weeks of pregnancypercentage of cycles started with the intent of egg retrieval that led to a live birth.
Implantation rate6 weeks of pregnancyPercentage of the implanted embryos number for each group / number of transferred embryos.

Secondary

MeasureTime frameDescription
Fertilization rate16:19 hours after intracytoplasmic injection(ICSI)Percentage of fertilized oocyte (appearance of two pronuclei) / Number of injected oocytes
Cleavage rate72 hours after ICSIPercentage of cleaved embryos / Number of fertilized oocytes
Clinical pregnancy rateafter 6 weeks of embryonic transferPercentage of pregnant cases with fetal heart / transferred cases for each group
Blast rate5:6 days of ICSIPercentage of total blastocysts / Total cleaved embryos
High quality blast rate5:6 days of ICSIMorphological grading of trophectoderm and Inner cell mass using Gardner's criteria 1999, from grade A and B ( A is the highest quality). Total high grade embryos/ total blast embryos.
High quality day 3 embryos72 hours after ICSIHigh quality D3 embryos according to Gardner's criteria / total cleaved embryos
Cancellation rate5:6 days of ICSIpercentage of blast transfer cases who did not achieve blast stage (cancelled cases) / total number of blast stage cases
