DO NOT DO HOME IUI. Do not place anything into your uterus. No tubes no matter what kits you find on the internet. The reason for this is you can cause great infection and death. There are 3 parts to the vj (simplified). The main area of the vj (where the penis goes), then the cervix (this dips down like a cone and has a hole in the middle leads a tunnel up into the uterus) and the uterus. Where this post is talking about is inside the cervix (up in the tunnel) and into the uterus.
