AP PSYCHOLOGY

Detailed explanation-1: -A blastocyst is a ball of cells that forms early in a pregnancy, about five to six days after a sperm fertilizes an egg. It implants in your uterine wall, eventually becoming the embryo and then the fetus.

Detailed explanation-2: -Implantation takes place anywhere between 6 and 12 days after you ovulate. It most commonly occurs 8 to 9 days after conception. So the exact date of implantation can depend on when you ovulated, and whether conception occurred early or late in the ovulation window.

Detailed explanation-3: -About a week after the sperm has fertilized the egg, the zygote has traveled to your uterus. It’s now a growing cluster of about 100 cells called a blastocyst. The blastocyst then attaches itself to the lining of your uterus (the endometrium). This attachment process is called implantation.

Detailed explanation-4: -From the moment it hatches, it will take 48-72 hours for it to implant. So the embryo implantation is not happening at the same time as the embryo transfer. The embryo is transferred inside the uterus, and when it hatches from the shell, it starts digging and implanting.

Detailed explanation-5: -Day 1: The blastocyst begins to hatch out of its shell. Day 2: The blastocyst continues to hatch out of its shell and begins to attach itself to the uterus. Day 3: The blastocyst attaches deeper into the uterine lining, beginning implantation. Day 4: Implantation continues.
