Ovarian cysts can develop for a variety of reasons, but the most common cause is related to the menstrual cycle. During each menstrual cycle, a woman's ovaries release eggs through structures called follicles. In some cases, a follicle may not release the egg as normal and instead continue to grow, forming a follicular cyst. Similarly, after an egg is released during ovulation, the empty follicle can close up and fill with fluid, forming a corpus luteum cyst. Other types of ovarian cysts, such as dermoid cysts and endometriomas, form due to more complex factors such as genetic predisposition or hormonal imbalances. Furthermore, polycystic ovary syndrome (PCOS) is a hormonal disorder that can also contribute to the development of ovarian cysts. In some cases, follicular cysts resolve on their own within a few menstrual cycles. However, other types of cysts typically require medical attention, especially if they cause pain, discomfort, or other symptoms. Regular gynecological check-ups will ensure proper monitoring and management of ovarian cysts.
