Question

What is the mode of action of COPPER - T?
A. Suppression of fertilization by forming a membrane.
B. Disturbing the site of implantation of blastocyst
C. Acting as a barrier
D. None of the above

Answer 1

Copper T is the intrauterine device that is used for birth control. It is a form of long-acting reversible contraceptive. It acts as a spermicide within the uterus, increasing the level of copper ions, prostaglandins, and white blood cells within uterine and tubal fluids. It works by disrupting the sperm mobility and damaging the sperm making it hard for the sperm to fertilize the egg.

Complete answer:
The intrauterine device Copper t primarily acts by preventing fertilization. It is also known as an intrauterine coil that contains copper. It is the most effective form of birth control. This device is placed in the uterus and lasts up to $12$ years. Copper T acts as a spermicide within the uterus. The copper T increases the level of copper ions, prostaglandins, and white blood cells within uterine and tubal fluids. It stops the sperm and egg from meeting and changing the lining of the uterus. Though sperm and egg cannot meet, it’s difficult to fertilize.
Copper T primarily works by preventing the fertilization, not by suppressing the fertilization neither by disturbing the site of implantation of blastocyst.
IUDs that act as a barrier method are condoms, diaphragm, and sponges.
So, the correct answer is “Option D”.

Additional Information:
There are various methods of birth control. It is used to prevent pregnancy. The different methods include condoms, IUD, birth control pills, the rhythm method, vasectomy, and tubal ligation. All methods are different and the way of actions is also varied.
Though Copper T is the safest method, it also has some side effects that include severe bleeding, backache, cramping, bleeding in between periods, anaemia, etc.

Note:
Copper T is the intrauterine device that contains copper. It is also known as the intrauterine coil. It primarily works by disrupting sperm mobility, so that they can prevent the joining with the eggs. It is a spermicide that increases the level of copper ions, prostaglandins, and white blood cells within the uterine and tubal fluids. The increased level of copper inhibits sperm motility and vitality thus preventing the meeting of the eggs with sperm.
