  Purpose
The aim of this study is to examine whether incubation of human oocytes until pronuclear stage, in different culture media containing high and low concentrations of glucose affect fertilization differently, not only in standard IVF cycles, but also after intracytoplasmatic sperm injection.In addition, we wish to determine whether exposure of oocytes to different concentrations of glucose until pronuclear stage has further effect on embryo quality and development until the blastocyst stage.

Primary Outcome Measures:
  • Fertilization rate and embryo quality [ Time Frame: 6 days ]

Estimated Enrollment: 100
Study Start Date: February 2008
Estimated Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: I
IVF Procedure-IVF Medium
Other: Universal IVF Medium + ISM1 Medium
Sibling oocytes will be equally divided and incubated separately in different 4-well culture dishes containing either IVF medium or ISM1 Medium and while ICSI will be returned to the same culture dish following injection. Fertilization assessment will be performed approximately after 15-20 hours for standard IVF and 12-18 hours post ICSI performance. After assessment, fertilized oocytes from different culture media will be transferred separately into fresh culture dishes containing ISM1 medium only. The zygotes will be incubated until embryo transfer on day 2 or 3. Embryo quality will be assessed according to the morphology of blastomeres as well as it's developmental stage.
Active Comparator: II
IVF Procedure - ISM1 Medium
Other: Universal IVF Medium + ISM1 Medium
Sibling oocytes will be equally divided and incubated separately in different 4-well culture dishes containing either IVF medium or ISM1 Medium and while ICSI will be returned to the same culture dish following injection. Fertilization assessment will be performed approximately after 15-20 hours for standard IVF and 12-18 hours post ICSI performance. After assessment, fertilized oocytes from different culture media will be transferred separately into fresh culture dishes containing ISM1 medium only. The zygotes will be incubated until embryo transfer on day 2 or 3. Embryo quality will be assessed according to the morphology of blastomeres as well as it's developmental stage.
Active Comparator: III
ICSI Procedure - IVF Medium
Other: Universal IVF Medium + ISM1 Medium
Sibling oocytes will be equally divided and incubated separately in different 4-well culture dishes containing either IVF medium or ISM1 Medium and while ICSI will be returned to the same culture dish following injection. Fertilization assessment will be performed approximately after 15-20 hours for standard IVF and 12-18 hours post ICSI performance. After assessment, fertilized oocytes from different culture media will be transferred separately into fresh culture dishes containing ISM1 medium only. The zygotes will be incubated until embryo transfer on day 2 or 3. Embryo quality will be assessed according to the morphology of blastomeres as well as it's developmental stage.
Active Comparator: IV
ICSI Procedure - ISM1 Medium
Other: Universal IVF Medium + ISM1 Medium
Sibling oocytes will be equally divided and incubated separately in different 4-well culture dishes containing either IVF medium or ISM1 Medium and while ICSI will be returned to the same culture dish following injection. Fertilization assessment will be performed approximately after 15-20 hours for standard IVF and 12-18 hours post ICSI performance. After assessment, fertilized oocytes from different culture media will be transferred separately into fresh culture dishes containing ISM1 medium only. The zygotes will be incubated until embryo transfer on day 2 or 3. Embryo quality will be assessed according to the morphology of blastomeres as well as it's developmental stage.
