Embryogenesis starts with a rapid mitotic division of the zygote, immediately following fertilization.The cell mass produced at the end of the cleavage is referred to as the morula.The morula is developed into the blastula.The blastula in mammals is referred to as the blastocyst. Many reports have demonstrated the usefulness of time-lapse, but several of these studies have predicted embryo development in early cleavage, 8-11 with few reports addressing blastocyst selection from in vitro culture. All of the listed processes occur after oocyte activation & completion of meiosis II . Practice terms with the Crossword Puzzle. It gets fixed there for about a week after ovulation and this process is called implantation. Results: blastocyst formation rate was 36% in embryos with early cleavage and 19% in embryos without early Evaluating markers of embryo quality, applied on day three of in vitro culture, in their capacity to predict whether embryos will reach blastocyst stage found them to be correlated with embryo development until day five. In the first period of experiments, culture in a single medium, from fertilization to blastocyst led to disappointing results: low blastocyst formation rates and low implantation rates per blastocyst transferred. Which of these processes occur after oocyte activation & completion of meiosis II. Drops in gamete production and embryo development with increasing age led to a drastic decrease in patients having at least one expanded blastocyst (< 30 years, 82%; > or = 40 years, 36%). There is no difference in the cumulative pregnancy rates between cleavage-stage and blastocyst transfer (632 women; OR = 0.89; 95% CI, 0.64-1.22; day 2 to 3: 48.9%; day 5 to 6: 52.0%) when compared with blastocyst transfer .

Blastocyst formation is similar in obese and normal weight women: a morphokinetic study Hum Reprod . This video includes information about the process of cleavage and its characteristics. Approximately 24 hours after fertilization the zygote begins with the first cleavage division. 16-day embryo. The blastocyst is a structure formed in the early development of mammals.It possesses an inner cell mass (ICM) which subsequently forms the embryo.The outer layer of the blastocyst consists of cells collectively called the trophoblast.This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoel. The blastocyst consists of cells forming an outer trophectoderm (TE, trophoblast) layer, an inner cell mass (ICM, embryo blast) and a blastocoel (fluid-filled cavity). Introduction. look at pic. 1.

Purpose: To evaluate: (i) the influence of morphology at cleavage stage on blastocyst formation and implantation, and (ii) whether the transfer of low-quality embryos on day-three would be a better approach than the transfer at blastocyst stage. competence of embryos derived from oocytes matured slowly might be due to the loss of M-phase promoting factor activity .

In a typical ART treatment cycle, fresh cleavage-stage embryos are routinely transferred [].In recent years, with rapid progress in vitrification technology and blastocyst culture protocols, transfer of fresh and vitrified-warmed blastocysts, together with cryopreserved cleavage-stage embryos are now becoming more routine and commonplace in ART clinical practice [2,3].
