Abstract:
Pregnancy rates (method and user) were evaluated for 2245 women who participated in the phase III clinical trials of the Today contraceptive sponge. User and method pregnancy rates were similar for women of different ages and parities. The 1-year method and user pregnancy rates (life table per 100 women) were 8.2 and 5.6, respectively.
