Blastocyst grading is a critical process in assisted reproductive technology, used to evaluate the quality and developmental potential of embryos before implantation. It involves assessing the blastocyst's expansion, the quality of the inner cell mass, and the trophectoderm layer to predict the likelihood of successful pregnancy.

Blastocyst Grading

Assisted reproductive technology (ART) encompasses medical procedures used to address infertility, primarily involving the manipulation of eggs, sperm, or embryos to achieve pregnancy. The most common and well-known ART procedure is in vitro fertilization (IVF), which has evolved with advancements like intracytoplasmic sperm injection (ICSI) and preimplantation genetic testing (PGT) to enhance success rates and address genetic concerns.

Developmental potential of embryos

Embryo implantation is a critical stage in early pregnancy where the blastocyst attaches to the uterine wall, initiating the formation of the placenta and establishing maternal-fetal circulation. Successful implantation requires a synchronized interaction between a receptive endometrium and a competent embryo, influenced by hormonal and molecular signaling pathways.
