Thin endometrium is one of the important causes of menorrhagia, recurrent abortion, infertility and other diseases, which is difficult to treat and difficult to detect in the early stage. By reviewing the research literature in recent years, the author found that traditional Chinese medicine has good clinical efficacy and few side effects in the treatment of thin endometrium. It can not only directly promote the expression of related factors, inhibit inflammatory factors, regulate the level of estrogen in the body, promote cell proliferation or apoptosis, increase endometrial receptivity, but also regulate a variety of signal pathways, multi-target, all-round treatment of TE. The current clinical research shows that simple internal administration of traditional Chinese medicine, simple external treatment, internal and external combination of traditional Chinese medicine and the combination of traditional Chinese and western medicine can effectively treat thin endometrium and improve the clinical symptoms of patients.
