Anovulation is a disorder of ovulation in which the egg cells do not develop normally or cannot be expelled due to problems with the function of the hypothalamus, pituitary gland or ovaries, which regulate hormones. The cure for ovulation disorders varies from one cause to another, and most of them are able to expel mature egg cells after treatment. Common causes: 1. Ovarian factors: this is a common cause, due to polycystic ovary syndrome, adnexitis, ovarian dysplasia or other reasons, the ovaries are unable to release estrogen or luteinizing hormone normally, thus unable to produce mature egg cells and unable to ovulate; 2. Pituitary factors: if there is a tumor in the pituitary gland, or suffering from empty saddle syndrome, it will not be able to release gonadotropin, affecting 3. Hypothalamic factors: Hypothalamic hypogonadism may be caused by congenital causes, or it may be caused by head injury or tumor, which prevents the hypothalamus from releasing gonadotropin-releasing hormone normally and affects the function of the pituitary gland, resulting in ovulation; 4. or adrenal cortical dysfunction and severe malnutrition may also lead to anovulation. Prognosis: 1. Better prognosis: for polycystic ovary syndrome, adnexitis, tubal inflammation, malnutrition, trauma, etc., there is a good chance of cure as long as the doctor actively cooperates with the relevant examination and treats the primary disease or supplements the corresponding hormones; 2. The effect is not very satisfactory and may require long-term supplementation of sex hormones according to medical advice.
