Bilateral ovarian cystic dark areas are considered to be follicles or ovarian cysts, it is recommended to go to the hospital for specific tests to confirm whether the cystic dark areas are follicles or cysts. Usually cystic dark areas will be considered as follicles, which are normal tissues of the ovaries and are nothing to worry about. However, if the number of follicles is high, ≥10, polycystic ovary syndrome is considered, and relevant tests can be performed to confirm the diagnosis and appropriate treatment and management. If it is a cyst after examination, it may be a follicular cyst formed because the follicle has not ovulated after growing up. Follicular cysts are usually not particularly large, so there is no need to deal with them, and they will be absorbed on their own under normal circumstances.
