Dysmenorrhea:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Although primary dysmenorrhea has no known single cause, possible contributing factors include hormonal imbalances and psychogenic factors. The pain of dysmenorrhea probably results from increased prostaglandin secretion, which intensifies normal uterine contractions. (See Causes of pelvic pain, page 938.) Dysmenorrhea may also be secondary to such gynecologic disorders as endometriosis, cervical stenosis, uterine leiomyomas, uterine malposition, pelvic inflammatory disease, pelvic tumors, or adenomyosis.
Because dysmenorrhea almost always follows an ovulatory cycle, both the primary and secondary forms are rare during the anovulatory cycles of menses. After age 20, dysmenorrhea is generally secondary.

Premenstrual syndrome:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The list of biological theories offered to explain the cause of PMS is impressive. It includes such conditions as a progesterone deficiency in the menstrual cycle’s luteal phase and vitamin deficiencies. Although there’s no evidence that PMS is hormonally mediated, failure to identify a specific disorder with a specific mechanism suggests that PMS represents a variety of manifestations triggered by normal physiologic hormonal changes. Researchers believe that 70% to 90% of women experience PMS at some time during their childbearing years, usually between ages 25 and 45.

About prevalence and incidence statistics:
The term 'prevalence' of Premenstrual syndrome usually refers to the estimated population
of people who are managing Premenstrual syndrome at any given time.
The term 'incidence' of Premenstrual syndrome refers to the annual diagnosis rate,
or the number of new cases of Premenstrual syndrome diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
