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.
在一项针对康涅狄格州纽黑文地区急性腰椎间盘突出症流行病学的研究中发现，患有急性腰椎间盘突出症的女性比年龄相仿但无腰椎间盘突出症的女性生育活产婴儿的次数更多。然而，与同龄的其他女性相比，腰椎间盘突出症患者的流产次数并没有更多。在因腰椎间盘突出症接受手术的女性中，发现L5水平椎间盘突出的女性活产次数与腰椎间盘突出症之间存在关联，但L3水平椎间盘突出的女性则不存在这种关联。
