“…In the present study, the total failure rate and the frequencies of breakage, misdirection, and slippage were significantly lower for the FC2 than for the PFC. These data differ from those of a study conducted among sex workers in Enping City, China [16], which found the rates of total clinical failure to be similar for both types of FC. This difference might be due to the variation in study participants.…”

“…A more recent study tested improvement in FC knowledge and attitudes among female sex workers after introducing the FC for a period of 2 months; however, the study provided few details on how many of the FCs delivered were actually used or the context of FC adoption 26. A very recent publication compared the clinical features of the original prototype FC produced by the Female Health Company and a similar FC produced in China 27. None of these studies have assessed FC use in the context of MC use among sex workers in China.…”

SUMMARYObjectives-To describe female condom (FC) use, male condom (MC) use and overall levels of protected sex before, during and after FC education and promotion (using the original prototype FC) combined with MC promotion among female sex workers in three rural or small urban settings in southern China.Study design-The 1-year FC intervention was conducted by local health workers through outreach to establishments where sex work is conducted. Three serial cross-sectional surveys were conducted in each study town before, during and after the intervention along with process documentation throughout the intervention period.Methods-Cross-sectional data from pre-intervention (baseline) and 6-month and 12-month post-intervention surveys from three study sites are used in a descriptive comparison of the context of the sex industry, outreach in two phases of intervention, and FC adoption after the intensive intervention phase in each site.Results-Approximately 75-80% of eligible women working in sex establishments, varying from 74 to 155 participants for each survey, were recruited from three study sites. After introduction and promotion of the FC along with the MC during the community public health * Corresponding author. Tel.: +86 10 65296971; fax: +86 10 65225752. susuliao@mx.cei.gov.cn (S.

Among them, 10-30% had used the FC more than once. FC awareness increased following the intervention with much less variation across the three study sites. At baseline, 31-54% of participants across the three sites reported 100% protected sex in the last 30 days with all types of partners. At one of the sites with relatively low MC use before the intervention, the proportion of women reporting 100% protected sex in the last 30 days increased by 15%, and the proportion reporting nil protected sex in the last 30 days decreased by 13% between baseline and 12-month post-intervention surveys. More complex profiles of FC and MC use and protected sex were shown at the other two study sites, where ...

“…Three studies failed to provide sufficient information and were scored as having unclear risk of bias for both random sequence generation and concealment [31,36]. Three studies reported adequately on the methods of random sequence generation but failed to report on allocation concealment and were scored as having unclear risk of bias for allocation concealment [29,30,37]. The rest of the studies adequately reported random sequence generation and allocation concealment and were judged to have low risk of bias for both domains.…”

“…When we considered the seven studies that compared the new female condoms to the FC2, there was no significant difference in the total clinical failure rates when the cupid/cupid 2 condoms (2 trials, n = 900, RR [34,38], and Pheonurse (1 trial, n = 291, RR 1•00 95% CI 0•92 to 1•08) [37] were compared to the FC2. One conference abstract for a trial comparing the Wondaleaf condom to the FC2 reported total clinical failure rates of 5•3% and 7•5% respectively [36].…”

Effectiveness of the female condom in preventing HIV and sexually transmitted infections: a systematic review and meta-analysis

et al. 2020

View full text Add to dashboard Cite

Background: The effectiveness of female condoms for preventing HIV and sexually transmitted infections (STIs) remains inconclusive. We examined the effects of female condoms on the acquisition of HIV and STIs. Methods: We searched four databases, two trial registries, and reference lists of relevant publications in October 2018 and updated our search in February 2020. We screened search output, evaluated study eligibility, and extracted data in duplicate; resolving differences through discussion. We calculated the effective sample size of cluster randomised trials using an intra-cluster correlation coefficient of 0•03. Data from similar studies were combined in a meta-analysis. We performed a non-inferiority analysis of new condoms relative to marketed ones using a non-inferiority margin of 3%. We assessed the certainty of evidence using GRADE. Results: We included fifteen studies of 6921 women. We found that polyurethane female condoms (FC1) plus male condoms may be as effective as male condoms only in reducing HIV acquisition (1 trial, n = 149 women, RR 0.07, 95%CI 0.00-1.38; low-certainty evidence). However, the use of FC1 plus male condoms is superior to male condoms alone in reducing the acquisition of gonorrhoea (2 trials, n = 790, RR 0.59, 95%CI 0.41-0.86; high-certainty evidence) and chlamydia (2 trials, n = 790, RR 0.67, 95%CI 0.47-0.94; high-certainty evidence). Adverse events and failure rates of FC1 were very low and decreased during follow up. Although the functionality of newer female condoms (Woman's, Cupid, Pheonurse, Velvet, and Reddy) may be non-inferior to FC2, there were no available studies assessing their efficacy in preventing HIV and STIs. Conclusion: The use of female plus male condoms is more effective than use of male condoms only in preventing STIs and may be as effective as the male condom only in preventing HIV. There is a need for well conducted studies assessing the effects of newer female condoms on HIV and STIs.

A crossover comparison of two types of female condom

Abstract: There were no statistically significantly differences in performance between the 2 types of FCs tested, and most participants would accept using either in the future.
