Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): 1 year no pregnancy, with June 12 in the hospital to see, at that time said that the thin endometrium only 6MM, said this is the reason, I would like to ask this reliable? I want to ask if this is reliable. If no follicles grew, a thin lining is normal huh? If it didn’t grow when it should have, then it’s about abnormal ovulation again. Some people also have lesions of the lining, so you need to find out what the cause is. Note: There are often patients with such questions, so this Q&A is reflected as an article. It can be understood that thin endometrium belongs to a syndrome and it is necessary to find out what the cause is and then deal with the symptoms in order to finally solve the problem.
