You're certainly not alone in your interest of this method. Spermicide is a popular option for birth control because it is easily accessible, simple to use, and provides added lubrication. Results from recent scientific studies for newer alternatives look promising, but more research is still needed. Some of the new ingredients being studied that may be able to function as spermicide (and provi...
OBJECTIVE Rectal microbicides are needed to reduce the risk of HIV acquisition associated with unprotected receptive anal intercourse. The MTN-007 study was designed to assess the safety (general and mucosal), adherence, and acceptability of a new reduced glycerin formulation of tenofovir 1% gel. METHODS Participants were randomized 1:1:1:1 to receive the reduced glycerin formulation of tenof...
A broad-spectrum vaginal microbicide must be effective against a variety of sexually transmitted disease pathogens and be minimally toxic to the cell types found within the vaginal epithelium, including vaginal keratinocytes. We assessed the sensitivity of primary human vaginal keratinocytes to potential topical vaginal microbicides nonoxynol-9 (N-9), C31G, and sodium dodecyl sulfate (SDS). Dir...
The tenofovir trial is being conducted among 1 000 HIV-negative women attending the Ethekwini Clinical Research Site in Durban and the rural Mafakathini clinic at Vulindlela, 90 km Unlike the controversial two failed microbicides (Ushercell cellulose sulphate-based vaginal gel and nonoxynol-9), where trial participants seroconverted, the tenofovir gel does not act in the vaginal lumen to kill t...
OBJECTIVES Bacterial vaginosis (BV) is a prevalent vaginal infection that is now regarded as a risk factor in more serious pelvic and obstetric complications. Spermicides are known to have antimicrobial activity against other sexually transmitted diseases and the aim of this study was to test whether the causative organisms of BV were also susceptible to spermicides, in vitro. DESIGN Minimal ...
