The Impact of the Intensity of Ovarian Stimulation on Embryo Quality in Predicted Suboptimal Responders. A Randomized Controlled Trial
In Brief
A Phase 4 clinical trial evaluating Ovarian Stimulation with CC+rFSH and Ovarian Stimulation with rFSH for Infertility. Completed, enrolled 110 participants across 1 site.
Detailed Summary
The management of suboptimal ovarian responders remains a challenging task in IVF. These patients are frequently managed with an intense stimulation protocol of ovarian stimulation in order obtain the maximum number of embryos and, therefore, maximize the cumulative live birth rate. However, the concept of "the more the better" has been recently defied by the one of "mild stimulation". Defenders of this protocol state that with mild stimulation only the best quality oocytes are allowed to grow and, therefore, higher quality embryos will be obtained. However, the impact of the intensity of ovarian stimulation on embryo quality is far from consensual. Moreover, its effect on early embryo development has never been evaluated. Therefore, the investigators set out to perform this randomized controlled trial comparing the number of GQB and the morphokinetic parameters of early embryo development in infertile patients undergoing two different intensities of ovarian stimulation, a milder approach (CC plus 150 IU daily dose of rFSH) and a more intense approach (300 IU daily dose of rFSH).
