To begin with, it is important to remember that there are two types of intrauterine devices: hormonal and non-hormonal.

Hormonal IUDs

They are covered by a special coating that controls the release of the ovulation-blocking hormone. The hormone is kept out of the bloodstream so that the risk of complications is much lower than with other means of hormonal contraception.

What are the pros?

This IUD works for women who cannot take oral contraceptives as the hormone dosage is lower and there are no complications such as increased blood clotting or raising blood pressure. It is possible to choose from IUDs that last 3, 5, or 10 years.

They are made from high-quality antibacterial plastic so that allergic reactions to them are practically unknown. They don't result in an abortive effect. In the absence of ovulation, there is no fertilization. They help reduce menstrual pain.

Non-hormonal IUDs

These IUDs can be made from copper, silver, and even gold. The copper IUDs are the most popular and budget-friendly, lasting around 3 years.

The silver ones work for 7 years and provide both contraceptive and antibacterial effects, decreasing the risk of pelvic inflammation. The golden IUDs are known for their hypoallergenic effect.

What are the pros?

It is one of the most budget-friendly means of contraception when dividing the cost of the IUD insertion by the period of use. It doesn't affect the hormonal balance. There is no risk of interaction with other medicines.

Summary of IUD Pros and Cons

Those with genital infections, dysplastic changes in the cervix, birth defects of the uterus, or myoma are contraindicated for IUD.
