Successfully manufactured HIV-resistant IUD

American scientists at Northwestern University in Illinois have recently successfully created a convenient contraceptive ring that can prevent genital herpes and HIV for a long time.

Inventor Patrick Kiser, professor of biomedical engineering and obstetrics and gynecology at Northwestern University, invented a ring with thin tubes that gradually release two drugs: the anti-HIV drug tenofovir and the contraceptive levonorgestrel. When the ring is inserted into the vagina, the drugs will dissolve and take effect for several hours. Therefore, women do not need to wear the ring continuously, the effectiveness of the ring to prevent disease and prevent pregnancy lasts for 3 months.

Professor Patrick Kiser said the ring was designed to be as easy and effective as possible for women to use. They can put it in and even forget about it for a few months or take it out and put it in during sex.

The results of the trials showed that the amount of tenofovir released when inserted into the ring was similar to that released in the anti-HIV vaginal gel used in humans. In other trials, tenofovir also prevented herpes.

The researchers have conducted extensive testing on large and small animal models and are currently in the process of submitting a drug application to the FDA. This means that the HIV-protective IUD could be in clinical trials in the US and exported to other countries within the next five years. The IUD costs about $10, but the price could be reduced to about $5.

"We designed this ring for women's health, especially women in low-income countries. But I think that in the not-too-distant future, the product will resonate with women everywhere, for women who want to control their fertility and protect their health, and prevent sexually transmitted diseases," said Professor Kiser.
