The objective was to evaluate the impact of additional lubricant on condom breakage and slippage. Two hundred and sixty-eight couples used 6 new and 6 aged condoms during vaginal intercourse and were instructed to use 2 of each type with either water-based lubricant, oil-based lubricant or no additional lubricant. The use of either oil-based or water-based lubricant increased slippage rates of new and aged condoms, although only one pairwise comparison (oil-based lubricant vs. no additional lubricant) was statistically significant (8.5% vs. 3.8%, P = 0.004). The use of oil-based lubricant increased breakage, although not statistically significantly, in both new and aged condoms. Water-based lubricant did not impact the breakage rate of the new condoms and decreased the breakage rate of the aged condoms (no additional lubricant 4.5% vs. water-based lubricant 2.1%, P = 0.029). From a functional perspective, this study suggests that condom users should be told not to use oil-based lubricants. The negative impact of water-based lubricant on slippage may be outweighted by the protective influence on breakage, especially for aged condoms. Over three-quarters of the couples (76%) had at least some incorrect knowledge, according to current condom instructions, of the type of lubricant that should be used with condoms.
目的是评估额外使用润滑剂对避孕套破裂和滑落的影响。268对情侣在阴道性交时使用了6个新的和6个用过的避孕套，并被指示每种类型的避孕套中各有2个搭配水性润滑剂、油性润滑剂或不使用额外润滑剂。使用油性或水性润滑剂均会增加新的和用过的避孕套的滑落率，不过只有一组两两比较（油性润滑剂与不使用额外润滑剂）具有统计学意义（8.5%对3.8%，P = 0.004）。使用油性润滑剂会增加新的和用过的避孕套的破裂率，尽管无统计学意义。水性润滑剂对新避孕套的破裂率没有影响，且降低了用过的避孕套的破裂率（不使用额外润滑剂为4.5%，水性润滑剂为2.1%，P = 0.029）。从功能角度来看，这项研究表明应告知避孕套使用者不要使用油性润滑剂。水性润滑剂对滑落的负面影响可能会被其对破裂的保护作用所抵消，尤其是对于用过的避孕套。根据当前的避孕套使用说明，超过四分之三的情侣（76%）对与避孕套搭配使用的润滑剂类型至少有一些错误认知。
