The treatment time for ovarian chocolate cysts needs to take into account the size of the ovarian chocolate cyst, whether it is unilateral or bilateral, the patient’s age, and whether the patient has fertility requirements to determine the specific treatment plan. If the diameter of ovarian chocolate cysts is less than 4 cm, and the patient does not have any symptoms or fertility requirements, the patient can be temporarily observed. If the ovarian chocolate cyst is >4cm in diameter, it is recommended to undergo ovarian chocolate cyst removal surgery. However, if the patient has fertility requirements and combined with infertility, ovarian cyst removal surgery is not recommended and ovarian cyst puncture treatment can be considered after egg retrieval. If the ovarian chocolate cyst is >4 cm and the patient does not have any fertility requirements, laparoscopic chocolate cyst removal surgery should be performed about 7-8 days after menstrual cleansing. Ovarian chocolate cyst treatment protocols are relatively complex, not only after surgical treatment, because of the high recurrence rate, often surgical treatment or puncture treatment is followed by drug therapy to prevent recurrence. The exact type of medication applied to prevent recurrence depends on whether the patient has further fertility requirements and her age. If the patient is close to the age of menopause, the application of medication to prevent recurrence may be shorter, and some pre-application of progesterone may be sufficient. If the age is still relatively young, around 40 years, the medication for recurrence prevention may suggest the GnRH-a class of drugs, which is recommended to be applied for 3-6 months to prevent the recurrence of chocolate cysts.
