When the uterus is small, if ovulation and the lining of the uterus are normal, fertility is usually not affected in this case. If the uterus is small, ovulation is abnormal and the endometrium is too thin, there may be no fertility. Clinically, the ability to become pregnant is determined primarily by the function of the uterus and ovaries. If a woman’s uterus is mildly small, but her ovaries function normally, she can have normal menstruation, and her uterine lining is well-developed, she will basically fulfill the conditions for conception. If the uterus is small and ovarian dysfunction is also present, resulting in low or no menstrual flow and insufficient endometrial tolerance, fertility will be affected. If a woman finds that her uterus is small, she must go to the hospital for examination to clarify the cause of the small uterus, and standardize the treatment under the correct guidance of the doctor.
