Structural integrity of the female condom after multiple uses, washing, drying, and re-lubrication.

Establishing the safety of re-using the female condom could significantly increase women's access to barrier methods especially in poorer countries. In this study, the structural integrity of female condoms was tested (n = 295) after multiple acts of vaginal intercourse. Fifty women were recruited to the study. Each woman re-used one condom up to eight times and washed, dried, and re-lubricated between each use. Structural integrity was measured using standard quality control testing; water-leakage, air-burst, and seam tensile strength. All results were compared to the United States Food and Drug Administration (US FDA) standards for an unused female condom. The results of the structural integrity tests for all cycles were above the FDA minimum standards for seam strength and burst tests. There was no deterioration detected in condoms used 8 times when compared to new female condoms in these tests. Five holes were detected by the water leakage test across all cycles, of which three were detected by the subjects themselves and reported to the investigators, therefore, giving a breakage rate of 1.7%. The holes were not associated with increased number of uses. This study provides further evidence that suggests the structural integrity of the female condom after multiple use is still within FDA minimum standards, although random holes resulting from handling occur infrequently with the re-use procedure.

Temporary discontinuation: a compliance issue in injectable users.

This study examined compliance in injectable users and followed women post-discontinuation to document their contraceptive practices. A cohort of 189 predominantly new users of depot-medroxyprogesterone acetate and norethisterone oenanthate were recruited and followed for 2 years regardless of whether or not they continued the method. Continuation rates were 42% at 1 year and 21% at 2 years. Of the 78 women who discontinued the method, 31 reported that they were "taking a break." For 20 of these women, this break (nonuse segment) occurred within the 2-year period, and 15 of them returned to the injection before the end of study period. The other five switched methods after the nonuse segment. The mean length of the nonuse segment was 7 months (range 2-13 months). In all 20 women, no other contraceptive method was used, they remained sexually active, and started the break within 6 months of commencing use of the injectable. In addition, 11 women were in a self-reported nonuse segment at the end of the study and stated their intention to return to the method at a later date. Menstrual disturbances were cited as the main reason for the break. Strengthened counseling at method acceptance was identified as a strategy to decrease the frequency of breaks in injectable method use.

The acceptability of reuse of the female condom among urban South African women.

This study assessed whether reuse of the female condom was acceptable among two groups of women in central Johannesburg, South Africa, who were taking part in two separate studies of female condom reuse. The first group consisted of women (aged 17 to 43 years) attending a family planning/sexually transmitted infections (STIs) clinic who were participating in a cross-sectional survey of the acceptability of female condoms reuse (n = 100). The second group included women (aged 18-40 years) at high risk for STI (80% self-declared sex workers) who were taking part in an ongoing cohort study to investigate the safety of reuse of the female condom through a structural integrity and microbial retention study (n = 50). Among women participating in the acceptability study, 83% said that they would be willing to reuse the female condom, and 91% thought the idea of reuse of the female condom was acceptable. All women taking part in the safety of reuse study and who reused the female condom up to seven times (n = 49) reported that the steps involved in reusing the device were easy to perform and acceptable. All 49 women said they would reuse the female condom at least once, while 45% said they would use it a maximum of seven or eight times. From the results of the interviews with both study groups, it can be concluded that, among women in a South African urban environment who have used a male and/or female condom, the concept of reuse of the female condom is acceptable and thought to be a good idea.

Vaginal discharge: a perceived side effect and minor reason for discontinuation in hormonal injectable users in South Africa.

Poor compliance and high discontinuation rates have been observed in users of injectable hormonal contraception in South Africa. The objective of this study was to assess the side effects and reasons for discontinuation in new users of both depot-medroxyprogesterone acetate (DMPA) and norethisterone oenanthate (NET-EN). One hundred and eighty nine women were recruited into a two-year follow-up study. At each visit for a repeat injection, users were asked about bleeding patterns and side effects. Vaginal discharge, often described as watery in consistency, was perceived to be a problem amongst women and their partners. In total, one fifth (20%) of women reported an increase in discharge during use of the method and three women cited this discharge to be the primary reason for discontinuation of the method. This side effect was mainly noted in the first few months of use. Health care providers believed that this was a side effect of both DMPA and NET-EN, and women who presented with this complaint were rarely investigated for presence of sexually transmitted diseases.

In vitro assessment of the structural integrity of the female condom after multiple wash, dry, and re-lubrication cycles.

Since the introduction of the female condom in the early 90s, there have been numerous reports of reuse of the device. In response to these reports, studies were undertaken to evaluate the safety of female condom reuse. If reuse were shown to be safe, then programmatic costs of introduction of the female condom would be reduced allowing it to be more widely available. This article outlines the results of in vitro structural integrity testing of the female condom after multiple wash, dry, and re-lubrication cycles. Devices were tested up to 10 washes using water leakage, burst, and tensile seam testing. All results were compared to the United States Food and Drug Administration (US FDA) standards for an unused female condom. The results of the structural integrity tests for all 6 washing procedures examined in this study were above the FDA minimum standards for seam strength and burst tests. For the water leakage test, 3 of 6 washing procedures tested passed the required FDA minimum standards (no holes detected). From the results of the study, it seems that washing, drying, and re-lubricating the female condom up to 10 times leads to some deterioration in the structural integrity of the device for specified washing procedures. Further studies are currently being conducted to establish the safety of female condom reuse with respect to microbial retention, structural integrity after in vivo use, and viral permeability.

The practice and prevalence of dry sex among men and women in South Africa: a risk factor for sexually transmitted infections?

OBJECTIVES: To establish the prevalence of "dry sex" practice in a South African periurban population. To investigate the reasons for and factors influencing the practice of dry sex and to evaluate dry sex practice as a risk factor for sexually transmitted disease (STD). DESIGN: Cross sectional sample survey. METHODS: A random community sample of men and women aged between 16 and 35 in Gauteng Province, South Africa, were interviewed regarding the practice of dry sex using a structured interviewer administered questionnaire. RESULTS: Dry sex practices were reported by 60% of men and 46% of women. Among younger individuals dry sex practice is far more common among the less educated, but there was no significant difference between education groups in the older respondents. A higher proportion of men practising dry sex than not practising dry sex reported having a past history of STD infection (56% versus 41%) although this difference was only marginally significant (p = 0.05). There was no difference in reported history of STD between women who practised dry sex and those who did not. CONCLUSIONS: This study shows that dry sex practice is common in this community. The younger less educated group were the most likely to practise dry sex. Dry sex practice was associated with an increased prevalence of self reported STDs in men but not in women.
