Background: The aim of this study was to determine the outcome of IVF/ ICSI by modification of embryo transfer technique following embryo transfer. Materials and Methods: In this randomized trial study, two groups of infertile women (n = 55) aged %40 years underwent in vitro fertilization or intracytoplasmic sperm injection treatment cycles with or without 0.2 mL of air pushed into the catheter...

Abstract Study question Our aim was to analyse the embryo-maternal-interaction, focusing on insulin/IGF-system and lipid metabolism day 6 of pregnancy in reproductive young old rabbits. Summary answer Advanced maternal age has a decisive effect embryonic insulin/IGF-signalling metabolism, leading higher embryo loss already during preimplantation period. What is known The potential women decline...

Embryo implantation is a crucial step in mammalian reproduction. However, little is known regarding the physiological roles of microRNAs in the regulation of embryo implantation. Here we show that a minimum uterine expression of miR-181 is essential for the onset of embryo implantation. Both transient and prolonged transgenic expression of miR-181 led to impaired implantation, which can be resc...

INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...

Culture of bovine embryos with insulin-like growth factor-1 (IGF-1) can improve development to the blastocyst stage and embryo survival following transfer to heat-stressed, lactating dairy cows. Two experiments were conducted to determine whether IGF-1 could improve embryo survival and development at Day 14 after ovulation. In Experiment 1, non-lactating Holstein cows (n=58) were selected as re...
