Thank you for your query.
Chocolate cysts are a manifestation of endometriosis
Endometriosis can be treated by medical / surgical options.
Medical options include progesterone
preparations, danazol and GNrh Analogue
If disease is uncontrolled, surgical excision of cysts is required.
Actually, pregnancy and breastfeeding
are protective for endometriosis.
There is no known cure for it, nor any specific steps to prevent its recurrence, however as it is estrogen dependent condition, once you approach peri menopause, it automatically gets better.
