The cells should appear scalloped and cohesive. The inner cell mass (ICM, which will form the fetus) is also a very important to score and contributes to the overall grade of the embryo. This group of cells should be prominent in the cavity. Is 4AA or 5AA better? What isRead More →
Implantation. Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. What are the stages of implantation? Implantation consists of three stages: (a) the blastocyst contacts the implantation site ofRead More →
The transfer of two blastocysts at day 5 was more favorable than two embryos at day 3 in a cohort of 164 infertile women agedRead More →
Endometrial thickness is a critical element for the success of an IVF cycle, in fresh and frozen transfers. Several studies have assessed its impact on cycle outcomes, and the threshold used to consider an endometrial thickness as acceptable varies between 7, 8 or 9 mm according to studies. How thickRead More →
After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit. In the first stage of embryonic development, the zygote divides to form two cells; one will develop into a suspensor, while the other gives rise to a proembryo. What does the embryo sacRead More →
Because of the high implantation potential of blastocyst embryos, we should be cautious about the high potential for twins. Transfer of two good looking blastocysts can result in twin pregnancy rates as high as 50%. What week does the egg split for twins? In a typical identical twin pregnancy, anRead More →
Embryo: An organism in the early stages of growth and differentiation, from fertilization to the beginning of the third month of pregnancy (in humans). After that point in time, an embryo is called a fetus. What is the embryo period? After conception, your baby begins a period of dramatic changeRead More →
Both natural twinning and artificial twinning produce identical individuals or clones. The key difference between natural and artificial twinning is that natural twinning takes place inside the womb of the mother while artificial twinning takes place in the lab inside the Petri plates. What is artificial twinning used for? ArtificialRead More →
As you prepare for your frozen embryo transfer, eat foods like: Warm soups. Whole grains like quinoa, farro, and whole-grain pasta. Legumes like beans, lentils and chickpeas. Healthy fats like avocado oil, extra-virgin olive oil, walnuts, and seeds. Lean proteins like fish and chicken (look for low-mercury fish) What canRead More →
In this way the process can be used to introduce a vector into a single cell. Microinjection can also be used in the cloning of organisms, in the study of cell biology and viruses, and for treating male subfertility through intracytoplasmic sperm injection (ICSI, /ˈɪksi/ IK-see). What is a Microinjector?Read More →
