A comparison between Nova T and Copper T 200 Ag in Hungary

Area of Science:

• Reproductive Health
• Medical Devices
• Contraception

Background:

• Intrauterine devices (IUDs) are widely used reversible contraceptives.
• Comparative studies are essential to evaluate the effectiveness of different IUD models.
• Understanding the use-effectiveness of IUDs informs clinical decision-making and patient counseling.

Purpose of the Study:

• To compare the use-effectiveness of the Nova T IUD and the TCu 200 Ag IUD.
• To assess pregnancy rates associated with each type of IUD over a two-year period.

Main Methods:

• A randomized sequence insertion of 855 Nova T devices and 883 TCu 200 Ag devices.
• A comparative use-effectiveness study design.
• Tracking of unplanned pregnancy rates per 100 users for both IUD types over two years.

Main Results:

• After one year, gross pregnancy rates were 1.1 per 100 Nova T users and 2.1 per 100 TCu 200 Ag users.
• After two years, pregnancy rates were 3.1 per 100 Nova T users and 4.8 per 100 TCu 200 Ag users.
• No statistically significant difference in pregnancy rates was observed between the two IUDs.

Conclusions:

• The Nova T IUD demonstrated a trend towards higher contraceptive efficacy compared to the TCu 200 Ag IUD.
• Further research may be warranted to confirm potential differences in efficacy.
• Both IUDs represent viable options for long-term contraception.
