If a 27-year-old woman has a small uterus, the clinical management should be based on the clinical manifestations. If a 27-year-old woman has a small uterus, but her menstruation is regular, her menstrual cycle is normal, and her menstrual flow is normal, it may not affect normal conception, and she can achieve full-term delivery, no special treatment is needed clinically. If a 27-year-old woman has a small uterus combined with amenorrhea, it is clinically indicated that the small size of the uterus may be due to uterine dysplasia and poor ovarian function, and hormonal drugs can be used to promote the development of the uterus to achieve normal menstruation so that she can conceive normally.
