Artificial cycles do not cause ovulation. The main principle of artificial cycle is through exogenous supplementation of estrogen and progesterone to artificially promote cyclic changes in estrogen and progesterone in women’s bodies, so that the endometrium undergoes cyclic changes and thus comes to have a period, that is, menstruation, during the period of use of the drug the ovarian function is inhibited, follicles will not develop and mature and ovulate, therefore, the artificial cycle of menstruation will not be ovulated. It should be noted that the artificial cycle is prohibited for patients with thrombotic diseases, serious cardiovascular and cerebrovascular diseases, etc.; when regulating menstruation, the artificial cycle usually needs to continue to use the drug for three months. If the patient has the need for medication, it should be carried out under the guidance of a professional physician, so as not to blindly use the drug, resulting in adverse consequences.
