duodenal ulcer healing by eradication of helicobacter pylori without antiacid treatment: randomized control trial.

abstract background: this randomized controlled study was performed in an unselected ivf/icsi population to test the hypothesis that blastocyst transfers result in higher clinical pregnancy rates (cpr) per oocyte retrieval when compared with day 2 transfers. methods: blind randomization for transfer on day 2 (group 1) or day 5/6 (group 2) was performed before stimulation. oocytes and embryos were cultured in sequential media in 5.5% co2, 5% o2, 89.5% n2 and 90% humidity. a maximum of two embryos
abstract background: this randomized controlled study was performed in an unselected ivf/icsi population to test the hypothesis that blastocyst transfers result in higher clinical pregnancy rates (cpr) per oocyte retrieval when compared with day 2 transfers. methods: blind randomization for transfer on day 2 (group 1) or day 5/6 (group 2) was performed before stimulation. oocytes and embryos were cultured in sequential media in 5.5% co2, 5% o2, 89.5% n2 and 90% humidity. a maximum of two embryos was transferred. results: the two groups were similar for age, ivf indication, number of treatment cycles, rate of icsi/ivf, number of fertilized oocytes and number of embryos transferred. the cpr/oocyte retrieval was comparable in group 1 (32%) and in group 2 (44%), while the cpr/embryo transfer was significantly higher (p < 0.01) in group 2 (60%) than in group 1 (35%). similarly, the implantation rate per embryo transferred was significantly higher (p < 0.03) in group 2 (46%) than in group 1 (29%). the cryo-augmented delivery rate/oocyte retrieval was comparable in group 2 (36.3%) and in group 1 (28.6%). conclusion: this randomized study in an unselected population showed a significantly higher cpr/embryo transfer and a tendency toward a higher cpr/oocyte retrieval in patients receiving blastocysts when compared with day 2 transfers.
