Whether or not an ovary will still ovulate after the presence of a cyst depends on the specifics of the cyst and cannot be generalized. The ovary consists of a cortex and a medulla, with the surrounding part being the cortex, where the cysts mature and ovulate, and the central part being the medulla, which is mainly made up of blood vessels, lymph, and connective tissues that provide nutrients to the follicles. Ovarian cysts usually grow inside the medulla of the ovary. If the cyst is small, it does not have much effect on ovulation. If the cyst is large and compresses the cortex, and in severe cases the normal ovarian cortex cannot be seen, it will of course affect ovarian ovulation. It is also related to the nature of the cyst. If it is a chocolate cyst, the chances of ovulation and conception are lower than normal.
