Condoms were tested in an in vitro system simulating key physical conditions that can influence viral particle leakage through condoms during actual coitus. The system quantitatively addresses pressure, pH, temperature, surfactant properties, and anatomical geometry. A suspension of fluorescence-labeled, nm polystyrene microspheres models free human immunodeficiency virus HIV in semen, and condom leakage is detected spectrofluorometrically.

New super-thin mesh has the potential to be inserted into a woman's vagina to provide barely detectable contraception and HIV protection for several days. Condoms haven't changed much since the introduction of latex in the s for a reason: they work. Despite their effectiveness, condoms have not proved to be a sufficient solution for family planning and controlling HIV around the world.
For over two months, Palestinians in the Gaza Strip have been flying kites, birthday balloons and inflated latex condoms into Israel, relying on the gentle Mediterranean coastal breeze to push them across the border. Silly as they may sound, these weapons are no joke. Most of them carry metal mesh pouches containing a burning piece of coal or oil-soaked rag, which have sparked hundreds of fires in southern Israel, destroying thousands of acres of land and causing millions of shekels in damage.

Wire Mesh Tube shield "condoms"? Posted: May Tue 29, am. They are meant to be slipped over the drain hose to trap lint so as not to clog your drain.
The year-old responded with "Eggs Benedict" -- a portrait of the Roman Catholic leader created with 17, colored, non-lubricated condoms. Through this, she hopes to take aim at the church's stance on using condoms, but also promote sexual diversity and a more open discussion about sexual health. The entire project took hours spread over three years to complete, Johnson estimated -- hours individually opening the condoms, laying them out and planning, and hours threading them through wire mesh.
The condom has remained essentially unchanged since the s but now researchers at the University of Michigan are proposing a high-tech polymer as the next-generation contraceptive. Essentially unchanged since the s, researchers want to give the condom a high-tech makeover to better prevent HIV and, by reducing its effect on sexual pleasure, increase rates of use. The liquified polymers passed through an electric field that drew them into fibers several hundred nanometers thick, roughly the wavelength of visible light.
