To evaluate whether the measurement of urinary estrone glucuronide and luteinizing hormone (LH) concentrations with an at-home device is correlated with serum hormone levels within a natural cycle frozen embryo transfer protocol.
The hypothesis is that home urinary monitoring can reliably detect the LH surge and serve as a trigger for timing the FET. Results of this study may ultimately lead to change in clinical practice by reducing the number of clinic visits for serum monitoring, offering a more convenient, time and cost saving method of detection of LH surge. If the proposed protocol were feasible and widely accepted by patients, this would prompt the wide adoption of a less invasive but equally as effective FET protocol.

To determine in women undergoing IVF who are at high risk of multiple births (>35%), as calculated by the application of a predictive model - IVFsingleTM, if single embryo transfer will lead to both comparable clinical pregnancy rate (CPR) and other secondary outcomes such as live birth rate (LBR) and cumulative live birth rate (cLBR) in comparison to DET while reducing the incidence of multiple births (a secondary outcome measure).

The purpose of this study is to determine if growth hormone given 4 weeks before as well as during a cycle of in vitro fertilization will improve outcomes in women who have had previous failure with IVF treatment cycles using high doses of follicle stimulating medications and had a poor response (less than 6 follicles).
