Question

How long does blastocyst take to implant?

Answer 1

Blastocyst

1. Implantation occurs after 7-8 days of fertilization.
2. The fertilized ovum begins to divide and form the morula (8-16 cells) the embryo transforms into a blastocyst (100 cell division).
3. The outer layer of the blastocyst is known as the trophoblast, which attaches very well and is covered with a layer of zona pellucida
4. It prevents the insertion of the blastocyst into the fallopian tube. In 3-4 days, the blastocyst is transferred to the uterus.
5. Their zona pellucida disappears and a trophoblast layer adheres to the uterine endometrium and the embryo is implanted.
