Mammalian preimplantation development, which is the period extending from fertilization to
implantation, results in the formation of a blastocyst with three distinct cell lineages. Only one …

Success rates with IVF have improved remarkably since the procedure was first established
for clinical use with the first successful birth in 1978. The main goals today are to perform …

Objective To determine if the addition of continuous morphokinetic data improves
reproductive outcomes when all embryos are cultured in a closed system. Design …

Background Time-lapse imaging combined with embryo morphokinetics may offer a non-
invasive means for improving embryo selection. Data from clinics worldwide are necessary …

BACKGROUND: Sperm DNA integrity is essential for the accurate transmission of genetic
information. The clinical significance of this assessment lies in its association with not only …

Obesity may have an adverse effect on the outcome of IVF/intracytoplasmic sperm injection
(ICSI) treatment. In this study, the effects of increased body mass index (BMI) on oocyte and …

Objective: To investigate the predictive value of quantitative measurements of blastocyst
morphology on subsequent implantation rates after transfer. Design: Prospective …

Many strategies have been proposed for the selection of viable embryos for transfer in
human assisted reproduction. These have included morphological scoring criteria for day 1 …

OBJECTIVE: Variations in pregnancy rates (PR) between IVF programs are due to multiple
factors, including embryo quality. Standardized embryo grading systems have been …

BACKGROUND: In human reproduction, embryo implantation is complex and poorly
understood. At present, no single markers are used in routine treatment to assay …
