2. Mar 20,06 OMNI 2 Background In-vitro maturation (IVM)
Immature eggs are retrieved from ovary and mature in laboratory.
Once eggs are matured, in vitro fertilization (IVF) is then performed.
3. Mar 20,06 OMNI 3 Background In vitro maturation (IVM) of oocytes vs. conventional in vitro fertilization (IVF)
Proposed advantages of IVM:
Simplify treatment and reduces cost
Avoids potential side effects-weight gain, bloating, breast tenderness, nausea, mood swings, and OHSS
Fear of potential risk of malignancy associated with repeated cycles of ovarian stimulation.
4. Mar 20,06 OMNI 4 Overall Objective To assess biological, clinical, psychological and economical impact of in vitro maturation (IVM) of eggs
5. Mar 20,06 OMNI 5 3 Pillars
6. Pillar I: Biological assessment of IVM
7. Mar 20,06 OMNI 7 Biological approach for IVM group Objectives
To compare life cycles and occurrences of disease from IVF and IVM treated offspring
To compare gene profile in maternal placenta of IVM and IVF derived embryos
8. Mar 20,06 OMNI 8 Hypotheses IVM or IVF offspring have no difference in life cycles and occurrences of diseases.
Maternal placentas from IVM or IVF embryos do not have different gene profile.
9. Mar 20,06 OMNI 9 Research design Using animal models (mouse or rat), we will compare life cycles and occurrences of diseases after IVF or IVM
We will analyze gene profile in the maternal placenta using microarray after IVF or IVM embryo injection, and confirm this by real time PCR and western blot in the different gestational stages
10. Pillar II: Clinical, psychological, economical impact of IVM
11. Mar 20,06 OMNI 11 Objectives To evaluate:
Efficacy of IVM-pregnancy and live birth rates.
Safety of IVM-complication rates
Cost of health service
Psychological impact on infertile couples
12. Mar 20,06 OMNI 12 Hypotheses IVM treatment will result in comparable clinical efficacy as standard IVF (i.e. pregnancy and live birth).
IVM decreases the risk of maternal complications and does not increase the risk of fetal, neonatal and long term complications.
IVM is more cost effective than IVF
IVM reduces psychological stress of infertile couples
13. Mar 20,06 OMNI 13 Research Design Multicenter prospective randomized control trial comparing IVM to IVF
Cohort study-follow up babies from IVM vs. IVF and spontaneous pregnancy -1 year
Health economic analysis
Psychological assessment using validated structured questionnaire
Focus group discussion-clinicians, nurses, clients
14. Mar 20,06 OMNI 14 Outcomes Efficacy of IVM vs. IVF:
Fertilization
Implantation
Pregnancy
Live birth
Safety of IVM vs. IVF:
Maternal complications (i.e. OHSS, miscarriage)
Fetal complications (i.e. congenital anomalies)
Newborn (Gestational age, birth weight, APGAR)
Follow up of IVM vs. IVF vs. spontaneous pregnancy babies as a cohort
Cost-effectiveness of IVM vs. IVF
Impact of IVM and IVF treatment on psychological well being of infertile couples.
15. Pillar III: IVF and pregnancy complication and birth outcomes: a population based study
16. Mar 20,06 OMNI 16 Objective To assess the effects of IVF and IVM on pregnancy complications and perinatal outcomes
17. Mar 20,06 OMNI 17 Methods-subjects A population-based retrospective cohort
