Menarche is usually related to the size of the uterus.
If the uterus is too small, the endocrine function may be impaired, resulting in a childish uterus, which may cause late menarche, or even lead to poor development of the ovaries, which may lead to women not having menstruation. Small uterus caused by uterine dysplasia is often due to abnormal secretion of estrogen and progesterone, so menarche and uterus size are usually related to each other.
Adolescent girls should pay attention to ensure good sleep, reasonable diet, appropriate exercise, pay attention to vulvar hygiene.
If there is a late menarche, it is recommended to go to the hospital in time for relevant examinations, so as to avoid delaying the condition and causing adverse effects.
