Time Magazine story: Spray-on condoms still a hard sell.

Edison had his lightbulb, Ford had his Model T, and Jan Vinzenz Krause has his spray-on condom. Inspired by the mechanics of a drive-through car wash, the German sexual-health educator designed a custom-fitting male contraceptive using liquid latex and some materials from a hardware store. "I felt a little like MacGyver," he says of building the contraption.

Offering a wide variety of condom options is not only a smart business move, it's good for public health. When used properly, condoms don't just act as contraceptives; they also prevent the spread of most sexually transmitted infections, including HIV. That means sexual-health educators, public health officials and condom brand CEOs alike are interested in finding ways to make condoms more appealing, especially to young people.

As a teenager, Krause, now 30, had trouble finding the right size condom, which set him on a quest to aid other similarly befuddled young men. In 2001 he developed an online condom adviser, which provides printable measuring tapes and instructions to help men determine which condom, out of all the brands available in Germany, will fit the best. According to Krause, more than 300,000 people have used the free service.

Hence his idea for a spray-on condom. The prototype, which began testing last year, consists of a hard plastic tube with nozzles that spray liquid latex from all directions, much like the water jets in the tunnel of a car wash. According to Krause, there are numerous advantages to his spray-on condom. "The condom fits 100% perfectly, so the safety is much higher than a standard condom's, and it feels more natural."

But there are some stumbling blocks. The men who tested the spray-on condom had a few hesitations, Krause says. Some were "a little bit afraid to use the tube" and would only try it on their fingers. Others worried that the mechanism, which hisses as it sprays, might ruin the mood.

But the most serious problem with the design — which is what has kept the product off the market thus far — is that the latex takes too long to dry. Liquid latex currently takes two to three minutes to vulcanize, making it impractical. "For people to buy it," Krause says, "it needs to be ready in five to 10 seconds."
