A limiting factor for couples trying to conceive naturally or with assisted reproductive technologies (ART) is the receptivity of the uterine lining. It is a long process for women going through an IVF cycle before finding out if they are pregnant. They begin with medication's during the IVF stimulation phase to grow follicles. They then watch and see how many egg's can be retrieved. The next step is to watch these embryo's grow and wait to see if there are any to be transferred or frozen. The last part of the puzzle is to have these healthy little embryo's implant and wait for a blood test 2 weeks later. Anything we can do to help with these steps will increase pregnancy rates.
