It has been suggested that using additional spermicide with condoms provides added contraceptive effect and protection from infection, and that water-based lubricants may lower condom breakage rates. This questionnaire-based study investigated the use of additional lubrication with condoms amongst 525 female students presenting for post-coital contraception, and the current and past experience of condom and additional lubrication use amongst 481 controls attending the same health centre. Of those requesting post-coital contraception, 83% claimed condom failure as the cause, with 66% of the control group having also experienced condom failure at some time. Use of additional water-based lubrication was significantly associated with lower condom failure rates (odds ratio 8.88, 95% C.I.: 3.79, 20.8). Gender, regularity of use of condoms and using oil-based lubricants were not associated with higher failure rates. Additional lubricant use was not significantly associated with increased condom slippage.
有人认为，在使用避孕套时额外使用杀精剂可增强避孕效果并预防感染，水性润滑剂可能会降低避孕套破裂率。这项基于问卷调查的研究调查了525名前来寻求性交后避孕的女学生使用避孕套时额外使用润滑剂的情况，以及在同一健康中心就诊的481名对照者当前和过去使用避孕套及额外使用润滑剂的经历。在那些寻求性交后避孕的人中，83%称避孕套失败是原因所在，对照组中66%的人也曾在某些时候经历过避孕套失败。额外使用水性润滑剂与较低的避孕套失败率显著相关（优势比8.88，95%置信区间：3.79，20.8）。性别、使用避孕套的规律性以及使用油性润滑剂与较高的失败率无关。额外使用润滑剂与避孕套滑脱增加无显著关联。
