摘要

Human Reproduction Open, Volume 2017, Issue 3, 2017, hox022, The authors would like to apologise for a mistake that was in the originally published version of this article. The mistakes are as follows: Page 5, line 90: the original version reads "Using a conservative approach, we proceeded with the calculation of the adequate sample size needed to detect an increase of 10% (from 32% to 42%) in the intervention group using a two-side Fischer's exact test with a significance level (alpha) of 0.05", when it should correctly read "Using a conservative approach, we proceeded with the calculation of the adequate sample size needed to detect an increase of 15% (from 32% to 47%) in the intervention group using a two-sided Fischer's exact test with a significance level (alpha) of 0.05". We apologise for this error. This has always been the correct sample size calculation, as demonstrated by our submission to clinicaltrials.gov ( , states in the section "outcome measures", below "clinical pregnancy rate"), which, as can be noted in the history track changes, was submitted and remained unaltered since February 10th, 2014. However, at the time we submitted the protocol for publication in HRO, we unfortunately made a typing mistake which went unnoticed.
