Objective: To determine whether incubation in the integrated EmbryoScope time-lapse monitoring system (TMS) and selection supported by the use of a multivariable morphokinetic model improve reproductive outcomes in comparison with incubation in a standard incubator (SI) embryo culture and selection based exclusively on morphology. Design: Prospective, randomized, double-blinded, controlled study. Setting: University-affiliated private in vitro fertilization (IVF) clinic. Patient(s): Eight hundred forty-three infertile couples undergoing intracytoplasmic sperm injection (ICSI). Intervention(s): No patient intervention; embryos cultured in SI with development evaluated only by morphology (control group) and embryos cultured in TMS with embryo selection was based on a multivariable model (study group). Main Outcome Measure(s): Rates of embryo implantation, pregnancy, ongoing pregnancy (OPR), and early pregnancy loss. Result(s): Analyzing per treated cycle, the ongoing pregnancy rate was statistically significantly increased 51.4% (95% CI, 46.7–56.0) for the TMS group compared with 41.7% (95% CI, 36.9–46.5) for the SI group. For pregnancy rate, differences were not statistically significant at 61.6% (95% CI, 56.9–66.0) versus 56.3% (95% CI, 51.4–61.0). The results per transfer were similar: statistically significant differences in ongoing pregnancy rate of 54.5% (95% CI, 49.6–59.2) versus 45.3% (95% CI, 40.3–50.4) and not statistically significant for pregnancy rate at 65.2% (95% CI, 60.6–69.8) versus 61.1% (95% CI, 56.2–66.1). Early pregnancy loss was statistically significantly decreased for the TMS group with 16.6% (95% CI, 12.6–21.4) versus 25.8% (95% CI, 20.6–31.9). The implantation rate was statistically significantly increased at 44.9% (95% CI, 41.4–48.4) versus 37.1% (95% CI, 33.6–40.7). Conclusion(s): The strategy of culturing and selecting embryos in the integrated EmbryoScope time-lapse monitoring system improves reproductive outcomes.

transfer without reducing the chances of pregnancy in a cycle of assisted reproduction. To this end, different noninvasive embryo selection methods have been designed that provide information on how to distinguish embryos with better prognosis (1) There are different methods of embryo gradation (2), but they are all based on morphology, and evaluation of morphology under microscope is subject to observer subjectivity (1). One of the noninvasive embryo evaluation methods to have come into the limelight in recent years is the time-lapse 1287

Abstract Computer-automated time-lapse analysis has been shown to improve embryo selection by providing quantitative and ob-
jective information to supplement traditional morphology. In this multi-centre study, the relationship between such computerderived outputs (High, Medium, Low scores), embryo implantation and clinical pregnancy were examined. Data were collected from six clinics, including 205 patients whose embryos were imaged by the EevaTM System. The Eeva scores were blinded and not considered during embryo selection. Embryos with High and Medium scores had significantly higher implantation rates than those with Low scores (37% and 35% versus 15%; P < 0.0001; P = 0.0004). Similar trends in implantation rates were observed in different IVF centres each using their own protocols. Further analysis revealed that patients with at least one High embryo transferred had significantly higher clinical pregnancy rates than those with only Low embryos transferred (51% versus 34%; P = 0.02), although patients’ clinical characteristics across groups were comparable. These data, together with previous research and clinical studies, confirm

There are several ways to ensure that you are getting the best chance of pregnancy in IVF treatment. This fact sheet summarises the techniques available to help sperm selection in IVF-related treatment.
Conventional IVF: ~100,000 sperm added to each egg Mature sperm bind to a substance called hyaluronic acid (HA) as they make their way through the cells protecting the egg in the human Fallopian tube. This is one of several mechanisms the body is known to use to select a good sperm to fertilise the egg.
ICSI : Poor movement, number and shape ICSI with PICSI • Washed sperm are tested to see what
PICSI may improve pregnancy rates

embryos at the blastocyst stage were transferred into the uterus on day 5 by the TDT catheter set (CCD, Neuilly, France); if blastocysts did not develop, one or two morula were transfered, whereas lower-cell embryos were not transfered. Biochemical pregnancy was confirmed by the positive serum b-hCG test (> 48 mIU/ml) 15 days after the embryo transfer, and clinical pregnancy by an ultrasound scan of the gestational sac and the embryo heart beats 14 days after the positive b-hCG test.
SPSS (Statistical Package for the Social Science; SPSS Inc., Chicago, IL, USA) statistical program for Microsoft Windows was used for statistical calculations. The laboratory outcomes were expressed as fertilization rate (number of fertilized oocytes per injected oocytes), number of blastocysts (%), number of blaststocysts per cycle, and number of cycles with at least one blastocyst (%). The clinical outcomes were expressed as implantation rate (number of implanted embryos per transferred embryos), number of pregnancies, pregnancy rate per cycle, and number of spontanous abortions. For comparing categorical data, the chi-square (c2) test was performed, and Spearman’s rank correlation coefficient was used as a non-parametric measure of statistical dependence between the two variables.
