What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of two new polyurethane condoms compared to a regular latex condom. Researchers aim to determine the frequency of breakage or slippage for each type and assess which condoms couples prefer. They seek healthy couples in a monogamous relationship for at least three months who are willing to use only the trial condoms during the study. As an unphased trial, this study allows couples to contribute to research that could improve sexual health options.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications, but it mentions that you cannot use medications that are applied to the genital area or any medication that might interfere with condom use. It's best to discuss your specific medications with the trial investigator.

What prior data suggests that these condoms are safe for use?

Research has shown that polyurethane condoms are generally safe for use. One study found an 8.5% failure rate, including breaking or slipping off during use. Although this rate is higher than the 1.6% failure rate for latex condoms, polyurethane condoms remain effective.

Research also indicates that despite a higher breakage rate, polyurethane condoms still provide good protection. They are designed to help prevent pregnancy and sexually transmitted infections.

Overall, polyurethane condoms are well-tolerated and a good choice for those sensitive to latex. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about polyurethane condoms because they offer a non-latex alternative for birth control, which is ideal for individuals with latex allergies. Unlike traditional latex condoms, polyurethane condoms are thinner, which can enhance sensitivity while still providing effective protection. Additionally, polyurethane is more resistant to temperature and humidity changes, potentially extending the shelf life of these condoms compared to latex options.

What evidence suggests that this trial's condoms could be effective for birth control?

This trial will compare the effectiveness of polyurethane condoms with natural rubber latex (NRL) condoms. Research has shown that polyurethane condoms are slightly more prone to breaking or slipping off than NRL condoms. Specifically, studies found a breakage and slippage rate of 8.5% for polyurethane condoms. Regarding pregnancy prevention, the chance of pregnancy over six menstrual cycles was 2.4% with polyurethane condoms, compared to 1.1% with latex condoms. Despite these differences, both types of condoms effectively prevent pregnancy and provide protection. Polyurethane condoms also serve as a good option for individuals allergic to latex. ^{1 3 4 6 7}

Published Research Related to This Trial

The new polyurethane condom, Avanti, is thinner and stronger than traditional latex condoms, which may enhance sensation and pleasure during use.

While Avanti condoms are safe for those with latex allergies and can be used with oil-based lubricants, the FDA has not yet confirmed their effectiveness in preventing pregnancy or sexually transmitted diseases.

Plastic condom available in U.S. [2012]

A study involving 51 couples using a prototype polyurethane condom for 10 acts of intercourse over 4 weeks found that the condoms were safe, with only two minor irritation-related adverse events reported, both of which resolved without treatment.

The breakage and slippage rates of the polyurethane condoms were comparable to those of traditional latex condoms, indicating that they are a functional and acceptable alternative for users.

Safety, functionality and acceptability of a prototype polyurethane condom. Farr, G., Katz, V., Spivey, SK., et al.[2021]

A review of four pre-marketing studies found that polyurethane condoms have similar breakage and slippage rates compared to latex condoms, indicating comparable safety and reliability.

Consumer preferences leaned significantly towards polyurethane condoms over latex, citing advantages in comfort, sensitivity, and overall experience, which could lead to increased usage and better protection against sexually transmitted diseases.

The male polyurethane condom: a review of current knowledge. Rosenberg, MJ., Waugh, MS., Solomon, HM., et al.[2019]

The polyurethane eZ.on condom had a higher clinical breakage rate (5.6%) compared to the latex condom (0.9%), indicating it may not be as reliable in preventing breakage during use.

Despite the higher breakage rate, the eZ.on condom showed similar slippage rates to latex condoms and was preferred by nearly 30% of participants, suggesting it could be a viable alternative for those who cannot or choose not to use latex.

Randomized crossover trial comparing the eZ.on plastic condom and a latex condom. Cook, L., Nanda, K., Taylor, D.[2019]

A study comparing a new polyurethane condom (Sagami Original/Protex Original) to a standard latex condom found that the breakage rates were similar, with 0.6% for polyurethane and 1.3% for latex, indicating that both types are equally reliable in preventing breakage.

The polyurethane condom also showed a slippage rate of 1.1%, compared to 0.5% for latex, but this difference was not statistically significant, suggesting that the polyurethane condom is as effective as latex in terms of preventing slippage during use.

Clinical breakage, slippage and acceptability of a new commercial polyurethane condom: a randomized, controlled study. Potter, WD., de Villemeur, M.[2019]

In a study of 901 couples, the polyurethane condom had a higher 6-month pregnancy probability (9.0%) compared to the standard latex condom (5.4%), indicating that the latex condom is more effective for pregnancy prevention.

Despite being less effective, the polyurethane condom caused fewer genital irritations in females and was well-accepted by participants, making it a suitable alternative for those with latex sensitivities.

Contraceptive effectiveness of a polyurethane condom and a latex condom: a randomized controlled trial. Steiner, MJ., Dominik, R., Rountree, RW., et al.[2019]

In a study involving 360 couples, the polyurethane condom had a significantly higher breakage rate of 7.2% compared to 1.1% for the latex condom, indicating a higher risk of failure with polyurethane.

Despite the higher breakage rates, nearly half of the users preferred the polyurethane condom for its sensitivity, suggesting it may be a suitable alternative for those who cannot use latex condoms.
