#Silicone vaginal rings deliver antiviral drugs, protect women against HIV Researchers at University Jean Monnet of Saint-Etienne,
France have succeeded in developing a vaginal silicone ring that delivers molecules that act on both HIV and herpes virus.
despite the fact that silicone is a hydrophobic compound, "said Meriam Memmi, author of the study and Phd candidate at University Jean Monnet of Saint-Etienne, France.
This was possible due to the addition of a hydrophilic compound to the silicone, which allowed the drugs to be released from their reservoirs.
These preliminary results demonstrate the ability of silicone rings to continuously deliver hydrophilic antiviral drugs for a long period of time at a concentration that would be effective for neutralizing the viruses present in semen.
"The aim of our study was to develop a vaginal silicone ring that was nontoxic to the health of users
