They provide a smooth texture that is not easily felt during normal daily activities. 

For most individuals, the IUD strings are barely noticeable. 

They may feel similar to a fine fishing line or dental floss. 

How long does it take for IUD strings to soften?

The softening of IUD strings can vary from person to person. 

The strings are typically made of thin plastic threads, and their initial texture may feel firm or stiff.

Generally, the process of softening can take a few weeks to a few months after the insertion of the IUD.

While IUD strings are made of durable materials, breakage can occur in rare instances.
