3Daughters is a clinical development company focused on transforming women’s healthcare with a novel, innovative IUD.
Our mission is to revolutionize women’s healthcare with our targeted uterine drug delivery platform, starting with a groundbreaking contraceptive solution – a novel IUD.
More than just an IUD, we’ve developed an integrated system featuring a non-hormonal, frameless, magnetic IUD paired with our i-Slider™ inserter and r-Slider™ retriever. Once FDA-approved, this combination is designed to provide the best IUD experience for women.

3Daughters IUD
We are revolutionizing women’s healthcare with innovative therapeutics that address women’s needs.
For over 50 years, the plastic, T-shaped frame of IUDs has remained largely unchanged, causing insertion pain, requiring dangling strings for removal, and presenting a range of other challenges.
Now, imagine an IUD as part of an integrated system that is frameless, non-hormonal and conforms to your body. With our small, flexible, slender Slider™ for insertion and removal, we’ve created a solution that transforms everything women hate about traditional IUDs – with no strings attached!
We are currently in preclinical development and plan to file an IND and begin Phase 1 clinical trials in 2025.
T-Shaped Frame Pain Points

3Daughters’ integrated uterine drug delivery system is designed to deliver the best IUD experience and completely disrupt the $1.4B U.S. IUD contraceptive market.

The 3Daughters IUD is comprised of three magnetic elliptical shapes, each encased in copper (the active pharmaceutical ingredient), as part of an integrated system featuring our patented Slider inserter/retriever system. The three ellipses are preloaded in the i-Slider inserter and then delivered into the uterus. Designed to eliminate the need for a tenaculum and uterine sound, the i-Slider’s purpose is to provide a smoother and less painful insertion process.
Once in the uterus, magnetic forces cause the IUD’s ellipses to immediately self-assemble into a stable triangular configuration. For easy removal, the r-Slider retriever, equipped with a magnetic tip, allows for the removal of the ellipses – without the need for strings.
