The large ovaries may be caused by ovarian inflammation, polycystic ovary syndrome, ovarian cysts, ovarian tumors, etc. The treatment for large ovaries caused by different conditions is different, depending on which condition is causing the treatment. If the ovaries are large due to ovarian inflammation, anti-bacterial and anti-inflammatory treatment is needed. If the ovaries are large due to polycystic ovary syndrome, they can be treated with short-acting contraceptives and ovulation-promoting drugs. If it is caused by ovarian cysts, the cysts can be left untreated if they are not large and surgery is needed if they are large. If the ovaries are large due to ovarian tumors, surgical treatment is required. Pay attention to pathological examination, and if the tumor is malignant, chemotherapy or radiotherapy is required along with surgical treatment.
