Study Details

Study Description

Brief Summary

The relation between the timing of COC denudation and oocyte /embryo quality is controversial. The aim of this study is to examine whether timing of denudation of sibling oocytes has any effect on embryo quality.

Condition or Disease Intervention/Treatment Phase
  • Other: early denudation
  • Other: late denudation

Detailed Description

Retrieved sibling cumulus-oocyte complexes (COCs) will be randomly divided into two groups, in the first group denudation will be in 30 minutes after oocyte retrieval, in second group denudation will take place after 2 hours of incubation.

Arms and Interventions

Arm Intervention/Treatment
early denudation

Cumulus-oocyte complexes will be denudated in 30 min after oocyte retrieval

Other: early denudation
COCs will be denudated in 30 min after oocyte retrieval

late denudation

Denudation will be done 2 hr after oocyte retrieval

Other: late denudation
COCs will be denudated 2 hr after oocyte retrieval

Outcome Measures

Primary Outcome Measures

  1. Number of good quality cleavage embryos [3 days after microinjection]

    Quality of embryos will be assessed morphologically on day 3

  2. Embryo utilization rate [1 week after microinjection]

    Embryo utilization rate is defined as the number of embryos utilized (transferred or cryopreserved) per number of 2PN zygotes.

Secondary Outcome Measures

  1. Fertilization rate [16-18 hour after microinjection]

    Proportion of injected oocytes with 2PN the day after injection

  2. Cleavage rate [2 days after microinjection]

    Proportion of cleaved zygotes on day 2

  3. Blastulation rate [1 week after microinjection]

    Blastocyst rate per oocyte
