Information was obtained from 540 clients on the 3,754 occasions when condoms were used over a one-month period. One or more major problems, breakage, slippage, leakage or a combination of these, occurred in 410 (10.9%) events, involving 217 (40.2%) clients. Breakage occurred in 209 (5.6%) events and slippage in 243 (6.5%). Leakage was almost always associated with breakage or slippage. There was a small group of accident prone clients. Breakage was more common in younger and inexperienced clients and in those who had previously experienced breakage. There were some differences in breakage rates between brands of condoms. Poor fitting condoms and non-spermicidal condoms were associated with more breaks. Other contributing factors included vigorous sex, dryness and tearing with fingernails. Additional lubrication did not protect from breaks and saliva was associated with more breaks than expected. Oil-based lubricants were associated with less breaks than expected. On many occasions (66.0%), clients were aware of the break before ejaculation occurred. Slippage was more common in the inexperienced and in those who had previously experienced slippage. There was no association between brand of condom and slippage but poor fitting condoms were associated with more slips. The most common reason for slippage was the condom being left on too long. Additional lubrication did not affect slippage.
在为期一个月的时间里，从540名使用避孕套的客户身上获取了3754次使用信息。在410次（10.9%）事件中出现了一个或多个主要问题，即破裂、滑落、渗漏或这些问题的组合，涉及217名（40.2%）客户。破裂发生在209次（5.6%）事件中，滑落发生在243次（6.5%）事件中。渗漏几乎总是与破裂或滑落相关。有一小部分客户容易出现此类意外情况。破裂在年轻、缺乏经验的客户以及之前经历过破裂的客户中更为常见。不同品牌的避孕套在破裂率上存在一些差异。尺寸不合适的避孕套和非杀精避孕套更容易破裂。其他促成因素包括剧烈性行为、干燥以及指甲划破。额外使用润滑剂并不能防止破裂，而且唾液导致的破裂比预期更多。油性润滑剂导致的破裂比预期更少。在许多情况下（66.0%），客户在射精前就意识到避孕套破裂了。滑落在缺乏经验的客户以及之前经历过滑落的客户中更为常见。避孕套品牌与滑落之间没有关联，但尺寸不合适的避孕套更容易滑落。滑落最常见的原因是避孕套佩戴时间过长。额外使用润滑剂对滑落没有影响。
