Given that the so-called “mild” ovarian stimulation procedures, together with their underlying die-hard ideology are, finally, running out of steam under the blows of evidence-based medicine and patient choices, the time has come to take over the concept of “natural” in reproductive care—this time, in the name of efficacy. Indeed, numbers in France indicate the cost of live birth through in vitro fertilization (IVF)-embryo transfer (ET) exceeds US$15,000-, mainly because per-cycle effectiveness of treatments remains low in France and patients often need to undergo repeated cycles to finally conceive.
