How to avoid failed insertion/expulsion/perforation

Supervised training in a model (HUT®), the home uterine trainer, is important to become familiar with the anchoring technique of insertion of the frameless GyneFix®.

If you position your hand on the short tenaculum as shown, and you move the handle gently and controlled forward with your thumb of your left hand + your right hand, you will have perfect insertion control while you are aligning the uterus. This will help minimizing failed insertion as you go straight to the middle of the fundus which is the thickest part. Feeling the anchor penetrating the fundal tissue will provide you additional confidence

Insertion is as simple and straightforward as inserting a uterine sound. Failed insertion/expulsion is usually the consequence of improper insertion of the anchor for the full 1 cm penetration depth in the myometrium of the uterine fundus.

Anchor with marker (magnification x 1.5): Tiny metal piece (2 mm long and 0.5 mm in diameter). The marker is always visible on ultrasound examination.

Failure to anchor the GyneFix® in the fundus could also be the consequence of an acquired or congenital uterus anomaly (polyp, fibroid, septum etc.)


  • Follow the insertion instructions as demonstrated.
  • In case the uterus is small, measuring the thickness of the fundus may provide confidence and assurance.
  • Use a short speculum to be able to reach the fundus easily.
  • After insertion, a sonographic examination is compulsory to determine the position of the anchor related to the serosa.
  • A 3-D examination can provide good information about the uterine cavity
