Generally speaking, endometrial polyps of 7mm are relatively small and will generally have less of an effect on pregnancy. Endometrial polyps that are less than 10mm will generally have less impact on the implantation of the fertilized egg. If the endometrial polyp is larger, or if there are multiple endometrial polyps, then it may occupy a larger area of the endometrium, which in turn will affect the implantation of the fertilized egg, leading to abnormal vaginal bleeding and affecting pregnancy. If endometrial polyps are detected during pregnancy, it is necessary to go to the hospital regularly for pregnancy checkups and to observe the development and growth of the fetus. If endometrial polyps are detected before pregnancy, it is recommended to seek prompt medical attention and treat the condition under doctor’s supervision before getting pregnant.
