C) Lippes loop: Protect the users from contracting AIDS and STDs.
D) LNG-20 Acts as spermicidal means and decrease the contraceptive efficiency.

Answer 1

Hint: A thin copper-containing wire is wrapped around a flexible, "T"-shaped piece of plastic to create the simple copper-releasing IUD known as the CuT. It aids in the production of fluid in the fallopian tubes and uterus that kills sperm.

Complete Step by Step Answer:
A form of intrauterine device that contains copper is an intrauterine device (IUD) with copper, commonly referred to as an intrauterine coil. Within five days of unprotected sex, it is used as emergency contraception and for birth control. It is one of the most successful birth control methods, with a 0.7% failure rate after one year.
It aids in the production of fluid in the fallopian tubes and uterus that kills sperm. White blood cells, copper ions, enzymes, and prostaglandins are all present in this fluid. Due to the direct toxicity of copper ions to sperm, copper ions hinder conception by preventing sperm motility. Even if a small, aggressive spermatozoan successfully fertilises an egg, the environment's high concentration of copper ions hinders implantation of the fertilised egg and subsequent pregnancy.
Hence, option A is the correct answer.

Note: A doctor or nurse will insert an IUD, a tiny T-shaped plastic and copper device, into your uterus. It prevents pregnancy for five to ten years by releasing copper to prevent conception.
