DESCRIPTION (provided by applicant): The primary objective of this grant is to refine and test a prototype of the Comfort Condom(tm): a new condom made from silicone, a material that may offer better sensation and be less prone to breakage than latex or plastic. The Comfort Condom will feature several technological innovations, including: 1) strong, heavy- gauge material that feels like human tissue, creating sensation instead of acting as a filter to it, 2) a loose fit for greater comfort, 3) a discrete scrotal retention band to reduce the likelihood of slippage, and 4) highly stretchable material for better fit and comfort. There are five specific aims: 1. Fabricate three prototypes of the Comfort Condom(tm) from silicone using liquid injection molding. 2. Confirm that the Class VI medical grade silicone used in the Comfort Condom(tm) remains biocompatible after the manufacturing process. The completed condoms will undergo laboratory testing for cytotoxicity, sensitization, irritation, and systemic toxicity. All three prototypes will be tested. 3. Assess the structural integrity of the Comfort Condom(tm) by measuring tensile properties, leakage, permeability, airburst volume, and airburst pressure. All three prototypes will be tested. 4. Compare the safety, acceptability, and performance of the three Comfort Condom(tm) prototypes. A "Feasibility and Design" study will be conducted with ten heterosexual couples. Each couple will use six condoms (two of each prototype), rate various subjective features of each condom, and report on any breakage, slippage, or adverse events they may experience. 5. Compare the safety, acceptability, and performance of the best Comfort Condom(tm) prototype with a commercial male latex condom. A "Performance and Acceptability" study will be conducted with thirty-six couples. Each couple will use three Comfort Condoms(tm) and three latex condoms, rate various subjective features of each condom, and report on any breakage, slippage, or adverse events they may experience. For sexually active couples, condoms used correctly and consistently are the most effective method available to reduce the risk of transmitting HIV and other sexually transmitted infections (STI). Unfortunately, many individuals find latex condoms unacceptable. The development of new and improved condoms is a key component in combating the HIV/AIDS crisis.

描述（由申请人提供）：该资助的主要目的是改进和测试Comfort Condom（商标）的原型：一种由硅胶制成的新型避孕套，这种材料可能提供更好的感觉，并且比乳胶或塑料更不易破裂。舒适避孕套将采用几项技术创新，包括：1）坚固，重规格的材料，感觉像人体组织，创造感觉，而不是作为过滤器，以它，2）宽松的适合更大的舒适度，3）离散阴囊保留带，以减少滑动的可能性，和4）高度可拉伸的材料，以更好的适合和舒适。具体目标有五个：1。使用液体注射成型法从硅树脂中制造三个Comfort Condom（TM）原型。2.确认Comfort Condom（TM）中使用的VI级医用级硅胶在生产过程后仍具有生物相容性。完成的避孕套将接受细胞毒性、致敏性、刺激性和全身毒性的实验室测试。所有三个原型都将进行测试。3.通过测量抗张性能、泄漏、渗透性、空爆体积和空爆压力来评估Comfort Condom（TM）的结构完整性。所有三个原型都将进行测试。4.比较三种Comfort Condom（TM）原型的安全性、可接受性和性能。一项“可行性和设计”研究将在10对异性夫妇中进行。每对夫妇将使用六个避孕套（每个原型两个），评价每个避孕套的各种主观特征，并报告他们可能经历的任何破裂，滑动或不良事件。5.比较最好的Comfort Condom（TM）原型与商用男性乳胶避孕套的安全性、可接受性和性能。将对36对夫妇进行一项“表现和可接受性”研究。每对夫妇将使用三个舒适避孕套和三个乳胶避孕套，评价每个避孕套的各种主观特征，并报告他们可能经历的任何破裂、滑动或不良事件。对于性行为活跃的夫妇来说，正确和一贯地使用避孕套是减少传播艾滋病毒和其他性传播感染风险的最有效方法。不幸的是，许多人认为乳胶避孕套不可接受。开发新的和改进的避孕套是防治艾滋病毒/艾滋病危机的一个关键组成部分。
