Male and female condoms: Their key role in pregnancy and STI/HIV prevention

Male and female condoms are the only available Multipurpose Prevention Technologies (MPTs) that can prevent unintended pregnancy and sexually transmitted infections including HIV. If used correctly and consistently, condoms can provide levels of pregnancy protection similar to many hormonal methods. Condoms remain one of the most common methods used at first sexual intercourse and are relied on as a current use of contraception by adolescents in many regions of the world. Male and female condoms are safe and require no prescription; in particular male condoms are generally easy to access at low cost. Female condoms are more expensive than male condoms and less accessible; however, they have the advantage of being a female-initiated method. Condom users may experience some common challenges; however, recent advances in condom technology have led to new designs and modifications of existing products to improve quality and make them more attractive, acceptable and pleasurable for consumers and increase its use.

Condom use errors and problems: a global view

Background Significantly more research attention has been devoted to the consistency of condom use, with far fewer studies investigating condom use errors and problems. The purpose of this review was to present the frequency of various condom use errors and problems reported worldwide. Methods: A systematic literature search was conducted for peer-reviewed articles, published in English-language journals between 1995 and 2011. Results: Fifty articles representing 14 countries met criteria for inclusion. The most common errors included not using condoms throughout sex, not leaving space at the tip, not squeezing air from the tip, putting the condom on upside down, not using water-based lubricants and incorrect withdrawal. Frequent problems included breakage, slippage, leakage, condom-associated erection problems, and difficulties with fit and feel. Prevalence estimates showed great variation across studies. Prevalence varied as a function of the population studied and the period assessed. Conclusion: Condom use errors and problems are common worldwide, occurring across a wide spectrum of populations. Although breakage and slippage were most commonly investigated, the prevalence of other condom use errors and problems found in this review were substantially higher. As a framework for understanding the role of condom errors and problems in inadequate protection, we put forward a new model: the Condom Use Experience model. This model can be used to generate testable hypotheses for future research. Addressing condom use errors and problems in research and interventions is crucial to closing the gap between the perfect use and typical use of condoms.

A crossover comparison of two types of female condom

OBJECTIVE

To compare the performance and acceptability of 2 types of female condoms (FCs) among female sex workers (FSWs) in China.

METHODS

The present crossover survey trial was conducted in Enping City between September and December 2007.

RESULTS

There were no significant differences between the 2 types of condoms in cumulative rates of episodes of misdirection; participants experiencing discomfort or feeling the outer or inner ring of an FC; or the clinical breakage or turning inside out of an FC. The rates of total clinical failures were similar for both FC types. Moreover, 59.5% of the survey participants reported that either type was acceptable to them.

CONCLUSION

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.

A systematic review of randomised controlled trials of interventions promoting effective condom use

Background

Effective condom use can prevent sexually transmitted infections (STIs) and unwanted pregnancy. We conducted a systematic review and methodological appraisal of randomised controlled trials (RCTs) of interventions to promote effective condom use.

Methods

We searched for all RCTs of interventions to promote effective condom use using the Cochrane Infectious Diseases Group's trials register (Oct 2006), CENTRAL (Issue 4, 2006), MEDLINE (1966 to Oct 2006), EMBASE (1974 to Oct 2006), LILACS (1982 to Oct 2006), IBSS (1951 to Oct 2006) and Psychinfo (1996 to Oct 2006). We extracted data on allocation sequence, allocation concealment, blinding, loss to follow-up and measures of effect. Effect estimates were calculated.

Results

We identified 139 trials. Seven out of ten trials reported reductions in ‘any STI’ with five statistically significant results. Three out of four trials reported reductions in pregnancy, although none was statistically significant. Only four trials met all the quality criteria. Trials reported a median of 11 (IQR 7–17) outcome measures. Few trials used the same outcome measure. Altogether, 10 trials (7%) used the outcome ‘any STI’, 4 (3%) self-reported pregnancy and 22 (16%) used ‘condom use at last sex’.

Conclusions

The results are generally consistent with modest benefits but there is considerable potential for bias due to poor trial quality. Because of the low proportion of trials using the same outcome the potential for bias from selective reporting of outcomes is considerable. Despite the public health importance of increasing condom use there is little reliable evidence on the effectiveness of condom promotion interventions.

Female Condom and Male Condom Failure Among Women at High Risk of Sexually Transmitted Diseases

OBJECTIVE

The objective of this study was to study the frequency and determinants of breakage and slippage during female and male condom use.

GOAL

The goal of this study was to determine condom breakage and slippage rate.

STUDY

We conducted a 6-month prospective follow-up study of women attending 2 sexually transmitted disease clinics. Breakage and slippage rates were computed. Logistic regression was used to evaluate baseline characteristics and time-dependent behaviors.

RESULTS

A total of 869 women used condoms in 20,148 acts of intercourse. Breakage was less common for female condoms (0.1%; 95% confidence interval [CI], 0.05-0.21) than for male condoms (3.1%; 95% CI, 2.80-3.42). Slippage was more common for female condoms (5.6%; 95% CI, 5.10-6.13) than for male condoms (1.1%; 95% CI, 0.90-1.28). Rates significantly decreased with use and increased with number of previous failures. From first use to >15 uses, combined failure rate fell from 20% to 1.2% for female condoms (P < 0.0001) and 9% to 2.3% for male condoms (P < 0.01).

CONCLUSIONS

Both condoms may provide good protection against sexually transmitted diseases. Experience determines success with either condom.
