Hi Lisa, I appreciate you sharing your thoughts and opinions here. However, it is important to keep in mind that the definition of endometriosis is still contested by experts, and that the currently accepted definition in the medical science community among experts is that it is similar tissue. It is also true that it bleeds, however this is different than the shedding of the endometrial lining each month with one's period. The retrograde menstruation theory, which suggests tissue from the endometrium implants throughout the pelvis, is not considered fact and pretty much dismissed by a lot of experts.

Besides, if this were true, how would fetuses have endometriosis? Read more on that here: https://pubmed.ncbi.nlm.nih.gov/20471320/#:~:text=Research%20has%20recently%20found%20evidence,female%20fetuses%20analysed%20at%20autopsy.

A few cases of men having endometriosis have also been recorded. While rare, they should not be dismissed:

It's important to keep in mind that more research desperately needs to be done on endometriosis so we can fully understand this complex disease. In the meantime, it is certainly up for debate and we need to keep an open mind as to the answers to these important questions.

Thanks for the opportunity to share these things.
