A review of the clinical features, diagnosis and management of primary and secondary dysmenorrhea updates some old views. Dysmenorrhea is painful menstruation, either cramps with no visible cause, primary dysmenorrhea, or secondary to specific pelvic pathology. Primary dysmenorrhea occurs in as many as 50% of young women, only in ovulatory cycles, and usually limited to the first 48 or 72 hours of menstruation. Secondary dysmenorrhea can be caused by any of a dozen or so disorders such as endometriosis, pelvic inflammatory disease, IUDs, irregular cycles or infertility problems, ovarian cysts, adenomyosis, uterine myomas or polyps, intrauterine adhesions or cervical stenosis. Psychological factors are now known not to cause dysmenorrhea, only to add to the reactive component of the pain. The pain is due to uterine cramps, hypoxia or ischemia, due to overproduction of prostaglandins, leukotrienes or vasopressin. Thus, primary dysmenorrhea can be treated with oral contraceptives if the women wishes to take pills for contraception and they are not contraindicated, or with non-steroidal antiinflammatory agents for the full 72 hours after pain begins. Calcium channel-blockers are also used on a research basis; transcutaneous electrical nerve stimulation is sometimes effective. If these treatments are not effective, investigation for causes of secondary dysmenorrhea is indicated, preferably for laparoscopy.

The aim of this investigation was to compare the response of small arteries of the human tubo-ovarian vasculature to certain vasoactive agents. Ring preparations of the arteries were isolated and mounted in tissue chambers for isometric recording of wall tension. The arteries were exposed to the vasoactive agents adrenalin, prostaglandin F2 alpha and two vasopressin analogues. Adrenalin, prostaglandin F2 alpha, lysin-vasopressin and triglycyl-lysine-vasopressin all produced powerful vasoconstriction, the greatest efficacy being shown by and lysine-vasopressin. The maximum response occurred after addition of a third compound to a combination of two, irrespective of which combination was used. Adrenalin showed faster contraction velocity than the other agents. The results indicate that the human tubo-ovarian arteries may be constricted by a variety of physiological and pharmacological stimuli, at least partly acting via different effector mechanisms. It is proposed that these vasoconstrictive agents--alone or in combination--may be useful in conjunction with gynaecological endoscopic surgery, e.g. in tubal pregnancy or ovarian cysts.
