Summary
The innovative IUB (Intrauterine Ball) or SOF-T offers advanced contraception with zero intrauterine pregnancies in 368 insertions. Its improved design leads to high tolerance and effectiveness, minimizing removal rates for better women
Area of Science:
- Reproductive Health
- Contraception Technology
- Gynecology
Background:
- Intrauterine devices (IUDs) are established methods of long-acting reversible contraception.
- Further development of IUDs aims to enhance efficacy, safety, and patient tolerance.
- The IUB (Intrauterine Ball) or SOF-T represents an advancement over traditional IUDs.
Purpose of the Study:
- To evaluate the safety and efficacy of the IUB/SOF-T in preventing intrauterine pregnancies.
- To assess the tolerance and reasons for removal of the IUB/SOF-T compared to other IUDs.
Main Methods:
- Prospective study involving 368 IUB insertions over 48 months.
- Analysis of removal data from 277 insertions at two university centers.
- Assessment of tubal occlusion in 80 cases using various diagnostic methods.
Main Results:
- No intrauterine pregnancies were reported in 368 IUB insertions.
- Low removal rates due to side effects (bleeding, pain, infection, expulsion) were observed.
- Tubal occlusion was confirmed in 80 cases, suggesting a potential mechanism of action.
Conclusions:
- The IUB/SOF-T demonstrates high contraceptive efficacy, preventing intrauterine pregnancies.
- Improved ultrasound localization and soft ends contribute to its effectiveness and better tolerance.
- This advanced IUD offers a promising option for long-acting reversible contraception.
