Efficacy of commercial condoms in the prevention of hepatitis B virus infection.
Tips of synthetic and natural condoms were filled with serum samples containing either hepatitis B virus, herpes simplex virus, or cytomegalovirus, then fit over an 8-in. mechanical vibrator and inserted vibrating into sterile bath solutions for 30 min. Phosphorus 32-labeled hepatitis B and cytomegalovirus molecular probes and viral culture techniques for herpes simplex and cytomegalovirus were used to determine whether leakage of virus had occurred into the surrounding bath solutions. Natural condoms allowed leakage of hepatitis B virus but not herpes simplex virus or cytomegalovirus, whereas synthetic condoms prevented leakage of all viruses. These results suggest that natural condoms might not be effective in preventing sexually transmitted hepatitis B virus infection.
