This research study will compare two experimental condoms with a commercially available latex condom. We will enroll approximately 300 couples into the study to use a total of 15 condoms at home. If you join the study, you and your partner will use five polyurethane condoms of each design and five commercial latex condoms during the courses of approximately 9 weeks. All study supplies, including condoms and lubricant are provided at no cost to you. You and your partner may each receive up to $150 for your participation.
Our research study is trying to find out which dose of emergency contraception, sometimes referred to as EC or “the morning-after pill”, works best at preventing pregnancy in women over 176 pounds. We are comparing the standard dose of two types of EC currently on the market with an investigational higher dose of EC. Approximately 1200 women will take part in this study at different research centers across the US. If you join the study, you will be provided with emergency contraception and be followed for about one month.
