Question

Explain the mode of action of releasing IUDs. How are hormone releasing IUDs different from them?

Answer 1

Hint As we know IUD is the abbreviated form for intrauterine device. It is “T” in shape, and fits inside the female uterus. It helps in preventing pregnancy by stopping the sperm from reaching and thereby fertilizing the eggs. They are considered to be effective, safe for most women and also long-lasting.

Complete answer:
If an IUD is used correctly, chances of getting pregnant is less than one percent. They are hassle-free and are safe to use in cases of breastfeeding.
The copper IUDs main mode of action is to prevent fertilization. Copper acts as a spermicide within the uterus that increases the levels of copper ions, prostaglandins, and white blood cells within the uterine and also tubal fluids. IUDs with copper can disrupt implantation also.
