I have discovered through my experience that gynicological infection is the most common cause, especially when its chronic and neglected, however; minimal could be refered to hormonal changes or endometriosis. Now I working on research regarding this question to find out suitable answer.
Hi, the exact cause is not known but hormonal imbalance can lead to complicated ovarian cyst.
Maybe you find some useful information in:

Hi Omaima....it could be environmental or genetic that affect hormonal balance. kindly see attached review article.
It is important to differentiate the type of cyst. Each type has different etiology. Generally ovarian cysts can be classified into these categories: follicular cyst, corpus luteum cyst; endometrioma, dermoid cyct and cystadenoma. Polycystic ovarian (PCO) condition has many follicles that do not rupture.
Follicular cysts are due to disturbed LH release. Instead of rupturing the follicle, it lutenizes the inner follicular wall and the follicle stays on the ovary causing further hormonal disturbances like increased estrogen secretion and irregularity in periods.
Endometriomas are dark chocolate colour fluid filled cysts that develop on the ovary. They are linked to the endometriosis, etiology of which is of considerable debate. Menstrual contents spill out of the fallopian tubes and grow wherever they attach around the ovaries or uterus.
Corpus luteum cyst develops after follicle has ruptured. This type of cyst usually does not cause much hormonal disturbances and disappear after corpus luteum lysis. Dermoid cysts may contain fat or other tissue inside. Cystadenoma is non-cancerous growth on the outside of ovary.
Because you are doing research on the ovarian cysts, I suggest conducting thorough literature search as much work has already been done especially on endometriosis and polycystic ovarian syndrome (PCOS).
Dear doctors, thank you very much for your enriched detailed of answer, which I will be considered in thorough literature review and consideration; however, we have been taught all these mentioned causes, but gynecological infections and pelvic inflammatory diseases didn't listed in any kind of them, which I think, it play a fundamental role in the causation especially of those newly developed cyst; of course, to be more specific non adenoma type of cyst niether dermoid one.
The cause will depend on the age of patient as well.
Complicated ovarian cysts in young are caused by endometriosis and malignancy
In reproductive age group mostly due to infection (PID), endometriosis, previous surgery.chronic ectopic
in post menopausal complicated cysts first diagnosis should be malignany
