The Primary Care Body is the group that represents GPs in the island.
Dr Maitiu O Tuathail from the group said endometriosis "can be difficult to diagnose as it can present with a wide range of symptoms".
Dr O Tuathail added: "An MRI scan of the pelvis is a very useful test which can assist in the diagnosis of endometriosis but unfortunately GPs in Jersey cannot readily access MRI scans and this significantly hampers the diagnosis and management of many conditions."
GPs in the island also undergo regular education on diseases like endometriosis and recently the Primary Care Body held a specialist educational meeting on endometriosis.
Jersey Education Department said it "recommends that schools teach menstrual wellbeing at KS3 and KS4" and "topics that aren't covered in the Jersey Curriculum are then at the discretion of the school to allocate their teaching and learning budget to".
The curriculum includes health and wellbeing.
