Options

  1. ALippes loop - It attracts the macrophages stimulating them to accumulate in the uterine cavity.
  2. BCu-T - It delays pregnancy for longer period.
  3. CCu 7 - Makes the uterus unsuitable for implantation.
  4. DLNG-20 - Suppresses sperm motility

Correct answer

A. Lippes loop - It attracts the macrophages stimulating them to accumulate in the uterine cavity.

Step-by-step solution

Lippes loop is a non-medicated IUD. It induces a mild inflammatory response in the endometrium, which attracts macrophages and stimulates them to accumulate in the uterine cavity, thereby increasing the phagocytosis of sperms.
