The article appears to be discussing the potential link between blood in urine and the need for an endometrial biopsy. Here's a summary of the main points:

* Blood in urine can be a symptom of various underlying conditions, including endometriosis.
* Endometrial biopsy is a diagnostic procedure that involves taking a sample of tissue from the lining of the uterus (endometrium).
* The article suggests that an endometrial biopsy may be indicated for women who have blood in their urine, as this could be a sign of endometriosis or another underlying condition.
* The article does not provide specific information on how to perform an endometrial biopsy or what the results might indicate. It is likely that this procedure would require consultation with a healthcare provider and potentially additional testing.

It's worth noting that blood in urine can have many causes, and not all of them are related to endometriosis. Women who experience blood in their urine should consult with a healthcare provider to determine the underlying cause and appropriate course of treatment.
