Treatment Success Rates
There are several critical components that determine IVF infertility treatment success rates. These include female age, ovarian reserve and egg quality. At the Montreal Fertility Centre we are dedicated to optimizing your chance of success.
Please note that Quebec law mandates single embryo transfer for all women under age 37, and a maximum of 2 embryos for women age 37 or older.
