Abstract

BACKGROUND:

Menstrual pain can be alleviated after childbirth. The purpose of this observational study was to evaluate the natural progression of menstrual pain among nulliparous women at their reproductive age.

METHODS:

A questionnaire-based study of perimenopausal women with a history of primary dysmenorrhea was performed. The study subjects were recruited between July 1, 2001 and June 30, 2005. Severity of menstrual pain was graded using a multidimensional scoring system.

RESULTS:

A total of 247 nulliparous women with primary dysmenorrhea were enrolled, and of these, 218 patients were eligible for analysis. Patients who had more frequent intercourse (p = 0.016), fewer associated systemic symptoms (p = 0.028), and use of oral contraceptive pills (p = 0.039) tended to have a higher chance of an improvement in dysmenorrhea after age 40. Multidimensional scoring distribution over chronologic age revealed that patients had significantly improved menstrual pain after 40 years of age.

CONCLUSION:

For nulliparous women with primary dysmenorrhea, the severity of menstrual pain decreased significantly after age 40. More studies are needed to explore this phenomenon from a biochemical or molecular basis.
