... of FOXO1 expression suggests a potential role for FOXO1 in implantation and decidualization. Epithelial cells showed weak FOXO1 immunostaining in the cytoplasm of the proliferative phase, whereas cells displayed strong FOXO1 immunostaining in the cytoplasm and nucleus of the secretory phase...

...David R. Garris The ultrastructural aspects of the appositional phase of interstitial blastocyst implantation in the guinea pig have been investigated using scanning and transmission electron microscopy. Blastocysts measured 28–34 µm in diameter and were encased in the zona pellucida. Trophoblast...

... a considerable mortality, which for the greater part occurred after day 3 of pregnancy but before implantation. This embryonic mortality could be prevented by anti-hCG serum given 21 h after hCG. It is speculated that embryonic mortality induced by hCG is caused by a relatively long-lasting disturbance...

...H.J.A. Carp; D.M. Serr; S. Mashiach; L. Nebel Embryo transfer probably produces a lower incidence of implantation than the physiological incidence despite all other factors seeming similar. The only factor known to be present physiologically and absent in embryo transfer is the presence of sperm...

..., amniocentesis revealed monosomy X and the pregnancy was terminated at 18 weeks. The 2nd patient had an uneventful pregnancy and delivered a healthy baby. The results from the present study, demonstrating a low implantation rate after DIET of 2-day embryos, suggest that the endometrial stroma does not provide...

... in the cyst group (79.7 vs. 70.7%; p = 0.03). Consequently, the implantation rate was found to be significantly higher in the cyst group (28 vs. 19%; p = 0.02), although pregnancy and ongoing pregnancy rates were similar. Conclusion: The presence of an endometriotic cyst during the IVF cycle was demonstrated...

... at the materno-fetal interface. From our observations and studies from other groups, hCG was indeed shown to play a significant role in implantation and tolerance of the embryo, decidual differentiation and remodeling, as well as in placentation. The profile pattern of LH/hCG-R expression by endometrial...

...Marie Cohen; Paul Bischof Implantation in the human is unique. This uniqueness is characterized on the maternal side by a spontaneous and massive decidualization of the endometrium and on the embryonic side by an almost unlimited invasive potential. Human embryos express an intrinsic invasive...

... been made in increasing the success rate during fertility treatment. This document describes a wide range of projects carried out to increase the understanding in the field of embryo implantation research. The ‘Fruitful’ research network was created to encourage collaborations within the consortium...

...P.R. Koninckx; D. Barlow; S. Kennedy It has been assumed that endometriosis is a progressive disease, with growth and development of lesions being inevitable once the disease has started. The implantation and the metaplasia theories describe the mechanism of initiation of endometriotic lesions...
