Hysteroscopic Subendometrial Embryo Delivery (SEED), Mechanical Embryo Implantation

Background A major hurdle to improved in vitro fertilization (IVF) success rate is defective endometrial receptivity and implantation. Various techniques have been advocated to increase implantation while reducing side effects. Currently, embryo transfer (ET) is performed blindly without direct visualization. As such, we sought to develop a technique utilizing a flexible minihysteroscope with a...

Kisspeptin, unexplained infertility and embryo implantation

Objective The primary objective of the study was to compare baseline KP levels in females with different causes of infertility and then correlate it with the risk of failure to conceive, preclinical abortion and pregnancy after intracytoplasmic sperm injection (ICSI). MaterialsAndMethods AA longitudinal cohort study was carried out from August 2014 till May 2015 recruiting one hundred and twent...

Human implantation Implantation of the human embryo

Implantation of the Human Embryo

Implantation is the final frontier to embryogenesis and successful pregnancy. Over the past three decades, there have been tremendous advances in the understanding of human embryo development. Since the advent of In Vitro Fertilization, the embryo has been readily available to study outside the body. Indeed, the study has led to much advancement in embryonic stem cell derivation. Unfortunately,...

Human pre-implantation embryo development.

Understanding human pre-implantation development has important implications for assisted reproductive technology (ART) and for human embryonic stem cell (hESC)-based therapies. Owing to limited resources, the cellular and molecular mechanisms governing this early stage of human development are poorly understood. Nonetheless, recent advances in non-invasive imaging techniques and molecular and g...

Uterine Receptivity to Embryo Implantation

It is both flattering and humbling to be asked to address this topic, since quite a few people at this meeting could address it equally well or better. In fact, Koji wrote a review with almost exactly the same title 20 years ago (1). However, each of us would address the area somewhat differently. Over the years I have had the privilege of examining blastocysts and implantation sites of a large...
