If a woman does not ovulate, it will often lead to delayed menstrual cycles, or even amenorrhea, as well as anovulatory dysfunctional hemorrhage, so for women of different ages, the treatment will vary from person to person. For adolescent females, as the gonadal axis is not yet well developed, it may lead to anovulation, which may push back the menstrual cycle, or amenorrhea, or even anovulatory type of dysmenorrhea, which may lead to heavy bleeding and prolonged bleeding time, and then it is necessary to take progestins or estrogens to carry out symptomatic treatment for stopping bleeding, and after stopping bleeding, it is recommended that estrogen/progestins be taken to regulate menstruation. After the hemostatic treatment, estrogen-progestin combination preparation is recommended to regulate the menstrual cycle and promote ovulation. For women of childbearing age who want to have children but are not ovulating, the most important thing to do is to promote ovulation to get pregnant, so you can consider taking clomiphene or letrozole on the fifth day of menstruation to promote ovulation, and you also need to monitor the growth of the follicles by ultrasound to see how they are growing, and you can arrange intercourse to prepare for the pregnancy when the follicles are discharged. For perimenopausal or menopausal women, the lack of ovulation is a physiological manifestation of ovarian decline, so there is no need for any treatment.
