Question

The non-medicated IUD is
(a) Copper T
(b) Progestasert
(c) Lippes loop
(d) LNG 20

Answer 1

Hint: IUD stands for Intrauterine device. The non- medicated IUD is made up of inert material or from stainless steel or plastic that is used as a method of birth control designed for insertion into a woman's uterus.

Complete step by step answer:
Non- medicated IUD devices are made of plastic or stainless steel only. Lippes loop made of plastic (polyethene) impregnated with barium sulphate is still used in many parts of the world.
- Lipper’s loops IUD was commonly used from the 1960s to the 1980s.
- This is a plastic double “S” loop, a trapezoid- shaped IUD that closely fits around the contours of the uterine cavity reducing the incidence of expulsion.
- The time period of retained uterine devices varied from 22 to 44 years.

Additional Information:
- Development of IUDs began in the 1920s, with the first generation of IUD’s constructed from silkworm gut and flexible metal wire. Eg- Grafenberg star and Ota ring.
- Types of IUD
Non- hormonal IUD: Those IUD which doesn’t release the hormone. In non- hormonal IUD, sperm are killed.
- The First- generation of IUD doesn’t release anything. This is suitable for multiparous women.
- Example: Lippes loop
- The second generation of IDU only releases copper ions. This is suitable for nulliparous women.
- Example: Copper- 7, ML- Cu- 250, ML- Cu- 375.
Hormonal IUD: Also known as the third generation of IDU. In this IUD, progesterone hormone is used. Once placed in the uterus, these types of IDU slowly release small amounts of the hormone progestin to stop sperm from reaching the egg. Effective usually 7 days of the insert and usually T- shape.
- Example: Progesterone IUD and Levonorgestrel IUD.
- A novel progesterone (pg) releasing IUD. This device has a solid poly EVA (ethyl vinyl acetate) side arms and a hollow core.
- Progesteron releasing IUDs that is polyethylene ethylene vinyl acetate copolymer 38 mg of progesterone microcrystals (and barium sulfate) suspended in silicone oil.
So, the correct answer is, ‘(b) Lipper loops.’

Note:
- In 1968 Zipper added contraceptive metals Cu or copper and Doyle and Clewe developed progestin – releasing IUD.
- Advantages of IUD:
Simplicity
Insertion takes only a few minutes
Easily remove
Inexpensive
Highest continuation rate
A temporary method of contraceptive
