Letters to the Editor embryo replacement in conventional IVF/embryo transfer, rather than in patients with repeated failures.The statistical critique given by Dr Walters was mistakenly based on the 'small size' of our study.The determination of 'small' or 'large' is subjective and depends on the definition chosen.In clinical studies, an investigation comprising a group of 72 patients (as in our study) would not be considered 'small'.The issue of which statistical method should be used for analysis is still unresolved.Nevertheless, we do not intend discussing this point, which seems to be less relevant to our paper.Our data clearly show that the transfer of more than five embryos is most useful in patients with chronic failures.Since the publication of our paper, our data have continued to accumulate, and the results confirm the published material.In conclusion, we firmly stand by our recommendation that in cases of repeated failure, transferring more than the traditional four or five embryos should be performed.After all, it should be remembered that the achievement of pregnancy, even multiple, is the main desire of our patients and our goal as clinicians.
