Brief Summary
A protocol was developed to improve pregnancy results after IVM compared to results from studies in the literature. Differences from most published protocols include the use of the Steiner-Tan needle to optimize oocyte environment during oocyte retrieval, use of oral medications and very low doses of FSH, and delayed embryo transfer during subsequent warmed cryo-preserved embryo transfer. Eligible patient have a PCO pattern in their ovaries during transvaginal ultrasound.

Outcome Measures
Primary Outcomes (2)
Percentage of treated patients having a clinical pregnancy
ultrasound evidence of pregnancy in uterus or tissue evidence of pregnancy
12 weeks post transfer
Percentage of treated patients having an ongoing pregnancy
pregnancy with cardiac activity (by history or observations) after 12 weeks
10 months post transfer
Secondary Outcomes (5)
Percentage of retrieved oocytes which matured per patient
2 days post retrieval
Percentage of retrieved oocytes which fertilized per patient
4 days post retrieval
Percentage of fertilized oocytes which divided
6 days post retrieval
Percentage of fertilized oocytes which became blastocysts per patient
8 days post retrieval
Percentage of patients who have a biochemical pregnancy after therir first transfer
28 days post transfer
Other Outcomes (2)
Number of clinical pregnancies from subsequent transfers
up to one year after transfer of last patient enrolled
Number of ongoing pregnancies from subsequent transfers
up to one year after transfer of last patient enrolled
Study Arms (1)
All
EXPERIMENTALPatients requiring IVF treatment with PCOS or a PCO pattern in their ovaries who wish to undertake IVM (as a variant of their IVF procedure)
Interventions
Immature oocytes (rather than mature oocytes) are harvested as in IVF. These oocytes are allowed to mature in the laboratory before fertilization
Eligibility Criteria
You may qualify if:
- PCO pattern with \> 25 antral follicles
- AMH \> 3.5
You may not qualify if:
- BMI \> 35
- body morphology making transvaginal retrieval difficult or impossible
- complicating medical condition making pregnancy or IVF relatively contra-indicated
