Contributor toolkit
Welcome to the Contributor Toolkit. This resource provides healthcare professionals with all necessary forms, diagnostic guidance, and submission instructions for contributing confirmed cases to the IMP Registry.
Please ensure that all relevant documents, if required, are completed and sent to the study team after you receive your login details for case submission. Completed documents should be emailed to the address provided on the IMP Registry database website.

ℹ️ Diagnostic Criteria for IMP
To be accepted into the registry, cases must meet the following diagnostic standards:
-
Implantation of the gestational sac within the myometrium of the uterine corpus, located above the internal cervical os, and clearly separate from the interstitial portions of the fallopian tubes.
-
Implantation occurs beyond the endometrial-myometrial junction.
