Clinically, it is mainly based on the function of the uterus to determine whether pregnancy is possible. If a woman is able to have a normal period, it is basically certain that her uterus will not be small and will basically meet the conditions for seed conception. It is not the case that if you ovulate, you will have a period. Patients who are chronically infertile due to a small uterus can take oral medication to identify the anatomy of their uterus and to clarify whether the endometrium and myometrium are well developed. If the endometrium is not well developed, this condition can lead to infertility. Clinically, drugs such as estrogen and progestin can be selected for withdrawal tests to clarify whether the uterus is functionally defective. In principle, a small uterus size is not the same as an infantile uterus. An infantile uterus refers to a uterus with abnormal development, an unsound uterus, or a uterus without endometrium, which is unable to conceive. A woman with a small uterus alone, but who can have normal menstruation, can basically meet the conditions for pregnancy.
