<unk>  can be classified as either primary or secondary based on the absence or presence of an underlying cause. Primary<unk>  occurs without an associated underlying condition, while secondary<unk>  has a specific underlying cause, typically a condition that affects the uterus or other reproductive organs. Painful menstrual cramps that result from an excess of prostaglandin release are referred to as primary<unk> . Primary<unk>  usually begins within a year or two of menarche, typically with the onset of ovulatory cycles. Secondary<unk>  is the diagnosis given when menstruation pain is a secondary cause to another disorder. Conditions causing secondary<unk>  include endometriosis, uterine fibroids, and uterine adenomyosis. Rarely, congenital malformations, intrauterine devices, certain cancers, and pelvic infections cause secondary<unk> . If the pain occurs between menstrual periods, lasts longer than the first few days of the period, or is not adequately relieved by the use of non-steroidal anti-inflammatory drugs (NSAIDs) or hormonal contraceptives, this could be a sign for secondary causes of<unk> . When laparoscopy is used for diagnosis, the most common cause of<unk>  is endometriosis, in approximately 70% of adolescents. Other causes of secondary<unk>  include leiomyoma, adenomyosis, ovarian cysts, pelvic congestion, and cavitated and accessory uterine mass.
