What increases my risk for functional ovarian cysts?

A functional ovarian cyst sometimes develops near the end of the menstrual cycle, when an egg follicle fills up with fluid. Factors that may increase your risk for developing a functional ovarian cyst include:

• A history of a previous functional ovarian cyst.
• Current use of clomiphene, such as Clomid or Serophene, to start ovulation.
• Use of low-dose progestin-only contraception (such as some implants, pills and IUDs).
