Ovarian corpus luteum cysts are non-redundant cysts that appear after ovulation and change with the physiological cycle, mainly related to human chorionic gonadotropin. The corpus luteum will appear after ovulation. The diameter of the corpus luteum is about 203 cm, which is a cystic structure. If it continues to grow or continues to exist, it will lead to a large amount of fluid accumulation and ovarian corpus luteum cysts, which will gradually disappear or appear with the onset of menstruation. If there are no other abnormal changes, treatment can be unnecessary. If ovarian corpus luteum cysts affect daily life or cause endocrine disorders or infertility, they need to be treated in a timely manner so as not to have an impact on the body.
