Question

Which trophoblast layer is highly invasive and secretes lytic enzymes to erode the endometrium?

विकल्प

• Blastocoel

• Inner cell mass

• Syncytiotrophoblast

• Cytotrophoblast

Answer 1

The syncytiotrophoblast is highly invasive in nature and secretes lytic enzymes that erode the endometrium. These enzymes break down the uterine tissue, creating a path and burrow for the blastocyst to embed itself. This invasive capacity is essential for successful implantation.
