Embryo transfer can be performed after various durations of embryo culture, conferring different stages in embryogenesis. The main stages at which embryo transfer is performed are cleavage stage (day 2 to 4 after co-incubation) or the blastocyst stage (day 5 or 6 after co-incubation). [10]
[11]: 165 This is a horseshoe-shaped area near to the head of the embryo. By day 19, following cell signalling, two strands begin to form as tubes in this region, as a lumen develops within them. These two endocardial tubes grow and by day 21 have migrated towards each other and fused to form a single primitive heart tube, the tubular heart.
(day 20 of fertilization. [1]) Primitive heart tube is forming. Vasculature begins to develop in embryonic disc. (day 20 of fertilization. [1]) Embryo at 4 weeks after fertilization. [3] A 10mm embryo from an ectopic pregnancy, still in the oviduct. This embryo is about five weeks old (or from the seventh week of menstrual age).

The embryo becomes embedded in the endometrium in a process called implantation. In most successful pregnancies, the embryo implants 8 to 10 days after ovulation. [7] The embryo, the extra-embryonic membranes, and the placenta are collectively referred to as a conceptus, or the "products of conception".
Days before the embryo transfer, Chelsea found out she was pregnant, and he told ESPN they were happily surprised to go “from one to three.” They welcomed son Brandon John in 2020 and son ...
The duration of embryo culture can be varied, conferring different stages of embryogenesis at embryo transfer. The main stages at which embryo transfer is performed are cleavage stage (day 2 to 4 after co-incubation) or the blastocyst stage (day 5 or 6 after co-incubation). [1] Embryos which reach the day 3 cell stage can be tested for ...
On February 3, Sweitzer delivered her 8-lb. daughter, Melody Day Andrade, ... They were able to create an embryo in hopes that Melody could one day have a sibling. Then, it was time to buckle down ...
