Sometimes the hardest part is not knowing what is causing them and sometimes having an answer is a huge relief. Bless your heart for sharing that. Dr. Jen is here. What is this? There's three layers in the uterus, an inner layer and outer layer. Think about this as a Normal uterus. With this diagnosis these glands sink down and make the middle layer much thicker. This is something that a lot of times slips under the radar. You can diagnose it surgery. We can get hints a woman has it, but it can go under the radar. What are the chances being able to carry to term? That's an unknown. You need a lot of things going the right way. When you have a woman with multiple miscarriages you have to look at a lot of things. This is something that affects a lot of women. Once we can diagnose it, it's about managing and trying to take a different view to fertility. What are the symptoms? Mostly pain and bleeding. Women are not taken serious when they complain about these things. I like to remind people when you complain of something, that complaint needs to be taken seriously. The uterus can be enlarged and look enlarged on imaging. Any cure for this condition? No cure. There's management. The key is manage the symptoms. Sometimes hormonely, rarely surgically. Once you determine there is some trouble with the couple, you have to get your ducks in a row and hope for the best. So great of Gabrielle to step up and have this discussion. This is like when our grandmothers would say we have this problem and no one would talk about it. This is 2018. We need to bring women's health issues to the forefront. Yes. Jen thanks so much.
