At what stage of human development does implantation occur?

Step 1: Understand that fertilization is when a sperm meets an egg.
Step 2: After fertilization, the fertilized egg is called a zygote.
Step 3: The zygote begins to divide and grow, becoming a blastocyst.
Step 4: The blastocyst travels down the fallopian tube towards the uterus.
Step 5: Once the blastocyst reaches the uterus, it looks for a place to attach.
Step 6: The blastocyst attaches to the uterine wall, which is called implantation.
Step 7: This implantation usually happens about 6 to 10 days after fertilization.

Implantation – The process where the blastocyst attaches to the uterine wall, marking a key stage in early pregnancy.
Blastocyst Development – The stage of embryonic development that occurs after fertilization, leading up to implantation.
Timing of Implantation – Implantation typically occurs 6-10 days post-fertilization, which is crucial for understanding early pregnancy.
