GYN-CS® is a new concept in intrauterine device technology. It is fixed to the uterine fundus, is frameless and entirely flexible. The GYN-CS® 3 has a lifespan of 3 years and GYN-CS® 10 has lifespan of 10 years, both used in this study. The primary objectives are: Analyse the learning curve of the surgeon and the ease of insertion of the device.
This study is a mono-center, open-label, single-arm (non-randomized trial, in which each participant receives GYN-CS® 3 or GYN-CS® 10) prospective study for the insertion evaluation of GYN-CS®. Providing no complications occur, the women will remain in the study for 3 years.
The study will be conducted in 20 healthy women between 18 and 48 years scheduled for elective Caesarean section.
The learning curve parameters are the time of the procedure (starts after removal of the placenta when the uterus is completely empty and ends when the device is correctly inserted) and a scale for the ease of insertion of the device.
Following insertion of GYN-CS® 3 and 10, women will be reexamined at discharge, at 6-8 weeks, at 1, 2 and 3 years after insertion. At 3 years after insertion of the GYN-CS® 3, it will be removed during the follow-up visit. At 3 years after insertion of the GYN-CS® 10, the device doesn't need to be removed at the follow-up visit. During every visit a vaginal ultrasound and gynecological examination are performed as well as a satisfactory scale of the IUD is questioned at the patient.

At every follow-up visit, expulsion of the IUD will be asked and the reason will be described in a log.
| During the whole duration of the trial (from the insertion of the IUD until 3 years of follow-up) |
| Continuation rate | What is the reason for drop-out of the study? | during the whole duration of the trial (from the insertion of the IUD until 3 years of follow-up) |
| Patient satisfaction: Likert scale | Patient satisfaction by Likert scale at every follow up: very satisfied, satisfied, neither satisfied nor dissatisfied, dissatisfied or very dissatisfied. At removal, the ease of this action by the following scale for the physicians:
| at every follow-up visit during the trial (4 days after the insertion of the IUD, 6-8 weeks after placement, 1 year after placement, 2 years after placement, 3 years after placement of the IUD) |
| Ease if removal of the IUD | At removal, the ease of this action by the following scale for the physicians:
| at every follow-up visite (4 days after the insertion of the IUD, 6-8 weeks after placement, 1 year after placement, 2 years after placement, 3 years after placement of the IUD) |
| The pain of the patient during removal of the IUD: VAS scale | The pain will be measured using a VAS scale (1. no pain, 2. mild pain, 3. nasty pain, 4. severe pain, 5. unbearable pain) | 3 years after insertion of the IUD |
