2003 APR 10 - (NewsRx.com & NewsRx.net) -- The female condom was effective as barrier to semen during intercourse for women trained to use it.
"In 1996-1998, the authors measured prostate-specific antigen (PSA) in vaginal fluid to assess the frequency of female condom failure and to evaluate the association of self-reported failure with semen exposure," reported a group of researchers in the united States.
"Women at low risk of sexually transmitted diseases (n=210) were recruited in Birmingham, Alabama," stated Maurizio Macaluso and colleagues at the Centers for Disease Control and Prevention and the University of Alabama-Birmingham. "They were trained to use the female condom, sample vaginal fluid before and after condom use, and complete forms to report problems during each use. Semen exposure was assessed by comparing pre- and postcoital PSA levels in vaginal fluid. A total of 175 women used 2,232 condoms."
The investigators found, "The rate of semen exposure ranged from 7% to 21% of condom uses, depending on the exposure criterion. Exposure was more likely (21-34%) and more intense (mean postcoital PSA, 24.7 ng/mL) if participants reported a mechanical problem versus other problems or no problems (exposure rate, 5-20% in both instances; mean postcoital PSA, 9.6 and 7.8 ng/mL, respectively). In logistic regression ...
