Patient and total failure rate were significantly lower in the CU (0.6 and 2.8), in comparison with the TM sub-group (6.5 and 9.8). Diaphragms with spermicide are 84 percent effective, meaning 16 out of 100 women who use this method as birth control for a year will become pregnant. In addition, spermicides may increase the risk of cystitis by altering normal vaginal flora and allowing overgrowth of pathogenic strains of E.coli (Fihn, 1985; Hooton, 1991).

However, this study failed to recruit the planned number of participants and was consequently underpowered. OR contracept? Insufficient studies have been conducted to determine effectiveness without spermicide. One study found an actual pregnancy rate of 24% per year in women using the diaphragm without spermicide; however, all women in this study were given a 60mm diaphragm rather than being fitted by a clinician. We found one trial that looked at using the diaphragm with and without the spermicide. The spermicide is placed inside the diaphragm before insertion.
