A short narrative review of the feasibility of adopting mild ovarian stimulation for IVF as the current standard of care

Mild ovarian stimulation has been conceived, proposed and implemented in clinical practice as a safer and cheaper alternative to conventional strategies of controlled ovarian hyperstimulation in preparation for in vitro fertilization (IVF). Our aim was to summarize the key evidence on this topic and explore its possible role as the standard treatment option for women undergoing IVF. A short narrative review of the existing literature, with emphasis on mild ovarian stimulation clinical and cost effectiveness, as well as treatment limitations. Numerous studies highlight mild ovarian stimulation's favorable characteristics with respect to oocyte/embryo quality, reduced patient risk, and ease of intervention. There is, however, a need for high-quality laboratory environment. Limitations regarding poor responders, older women, or those seeking ovarian stimulation for non-infertility indications should also be considered. Finally, outcomes on the cumulative success rates and the cost effectiveness of mild ovarian stimulation remain inconclusive. Mild ovarian stimulation protocols for IVF should currently be implemented only in carefully selected populations. Further research is needed to clarify the remaining controversies in this IVF approach.
