Endometrial polyps refer to the hyperplasia of the endometrial lining due to inflammatory stimuli, resulting in many polypoid tissues. Whether endometrial polyps affect pregnancy mainly depends on the number and size of the polyps, and whether they cause clinical symptoms. First, if the polyps are small and few in number without causing an increase in menstrual flow, they generally do not affect pregnancy and do not require removal of the endometrial polyps, as removing them could instead easily damage the function of the endometrial lining. Second, if the polyps are large, over one centimeter, or there are multiple endometrial polyps, and they cause an increase in menstrual volume, this indicates that the endometrial polyps have impacted the woman's body. In such cases, it is necessary to use a hysteroscope to remove the endometrial polyps before trying to conceive.
