If multiple ovarian cysts are found by ultrasound, there are several possible causes: 1. If there are more than 12 follicles in each ovary bilaterally, it may be caused by polycystic ovary syndrome, which will be detected by ultrasound with corresponding changes in ovarian morphology, and other tests are needed to confirm the diagnosis. 2. Multiple follicles are growing and developing in the ovaries as a result of previous ovulation treatment. Therefore, multiple follicles will be found by ultrasound examination, mistaking them for cysts. It is recommended to continue monitoring the growth and development of the follicles by ultrasound. If you are planning to get pregnant, you may choose to have intercourse after the follicles have reached dominance to increase your chances of pregnancy and it is recommended to review after your period.
