title: Pregnancy and the syndrome of herniated lumbar intervertebral disc; an epidemiological study.
abstract: In a study of the epidemiology of acute herniated lumbar intervertebral discs in the New Haven, Connecticut, area, it was found that the female cases had had more pregnancies resulting in live births than women of similar age without known herniated discs. However, cases had not had more pregnancies resulting in miscarriages than other women of their age. Among women who underwent surgery for their herniated discs, the association between number of live births and herniated discs was found for women with herniations at the L5 level but not for women with herniations at the L3 level.
