Trophectoderm biopsy for preimplantation genetic test and technical tips: A review
Background Recently, the Japan Society of Obstetrics and Gynecology initiated a clinical study of preimplantation genetic test for aneuploidy. There will be a great need for a standardized embryo biopsy technique in Japan.

Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the effect of BMov

Cleavage stage versus blastocyst stage embryo transfer in assisted reproductive technology.
BACKGROUND Advances in cell culture media have led to a shift in in vitro fertilisation (IVF) practice from cleavage stage embryo transfer to blastocyst stage transfer.

Aneuploidy in the Human Blastocyst
Studies of human cleavage stage embryos, 3 days after fertilization of the oocyte, have revealed remarkably high levels of chromosome abnormality. In addition to meiotic errors derived from the gametes, principally the oocyte, mitotic errors occurring after fertilization are also common, leading to widespread chromosomal mosaicism.

Regulation of blastocyst formation
Preimplantation or pre-attachment development encompasses the "free"-living period of mammalian embryogenesis, which directs development of the zygote through to the blastocyst stage. Blastocyst formation is essential for implantation, establishment of pregnancy and is a principal determinant of embryo quality prior to embryo transfer.

Which Blastocyst to Be Biopsied? - Blastocyst Stage and Quality
This talk is an engaging format to address crucial aspects of selecting the most suitable blastocyst for biopsy to optimize the success of PGT procedures and successful pregnancies. The talk commences with an overview of various blastocyst stages and relevant morphological characteristics, elucidating the critical developmental milestones and key ...

Blastocyst implantation contains the following three processes: apposition, attachment, and invasion of the blastocyst. Ovarian hormone progesterone (P4) regulates these processes exquisitely.

Objective: The aim of this study was to screen the potential of human embryos to develop into expanding blastocysts following in vitro embryo splitting and then assess the quality of the generated blastocysts based on chromosomal characteristics and ...
