If the follicles are still developing on that day and the endometrium is synchronized with it, the doctor will inform the patient of the next visit or the time of intercourse; if the follicles are developing slowly or the endometrium is thin, the patient will usually be adjusted with ovulation-promoting drugs or estrogen. If the endometrium is found to be unevenly echogenic, the patient will be advised to cancel the monitoring and change to hysteroscopy to exclude polyps and other abnormalities. Irregular menstruation is usually indicative of anovulation. Reproductive endocrinology needs to be measured on the 3rd day of menstruation and if normal, ovulation will be promoted on the 5th day of menstruation; if endocrinology is abnormal, ovulation will usually need to be adjusted for 1-3 months before ovulation is promoted. Patients with polycystic ovary syndrome usually need to adjust for about 3 months and start ovulation promotion immediately after the endocrine is within the normal range, and should not wait for 1-2 months after stopping the medication, which will make the organism have endocrine abnormalities again and abandon the previous work.
