Diaphragm/spermicide use increases the risk of urinary tract infection (UTI). To determine whether spermicide-coated condoms are also associated with an increased risk of UTI, the authors conducted a case-control study at a large health maintenance organization in Seattle, Washington. Cases were sexually active young women with acute UTI caused by Escherichia coli, identified from computerized ...
Spermicide (i.e., female-mediated sperm death) is an understudied but potentially widespread phenomenon that has important ramifications for the study of sexual conflict, postcopulatory sexual selection, and fertility [1, 2]. Males are predicted to evolve adaptations against spermicide, but few antispermicidal mechanisms have been definitively identified. One such adaptation may be the enigmati...
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...
BACKGROUND In most recent large efficacy trials of barrier contraceptive methods, a high proportion of participants withdrew before the intended end of follow-up. The objective of this analysis was to explore characteristics of participants who failed to complete seven months of planned participation in a trial of spermicide efficacy. METHODS Trial participants were expected to use the assign...
BACKGROUND Staphylococcus saprophyticus is the second most common cause of urinary tract infection (UTI) in young women. Relatively little is known about risk factors for this infection including exposure to vaginal spermicides, which increases the risk of UTI caused by Escherichia coli. PATIENTS AND METHODS We conducted a case-control study in a large health maintenance organization Case pat...
the relation between periconceptional vaginal permicide use and sex ratio at birth, birth weight, and the frequency of congenital anomalies was examined in a cohort of 2,712 new york city obstetric patients, 149 of whom (5.5 per cent) became pregnant while using spermicides or had used spermicides before and after conception. periconceptional spermicide use was not associated with any important...
