OBJECTIVES: To estimate and compare the effectiveness and safety of 5 spermicides over 6 and 7 months of use, respectively. The spermicides included 3 gels containing 52.5 mg, 100 mg, and 150 mg of nonoxynol-9 per dose and a film and a suppository, each containing 100 mg of nonoxynol-9 per dose. METHODS: Women wishing to use only spermicide for contraception for 7 months were randomly assigned to use 1 of the 5 spermicides with emergency contraception backup. Participants were followed up for… Expand
Contraceptive Efficacy, Acceptability, and Safety of C31G and Nonoxynol-9 Spermicidal Gels: A Randomized Controlled Trial
TLDR
C31G demonstrated noninferior contraceptive efficacy compared with nonoxynol-9 and may provide another marketable option for women seeking spermicidal contraception. Expand
Acceptability of five nonoxynol-9 spermicides.
TLDR
All five nonoxynol-9 (N-9) spermicides were considered acceptable by most users and did not appear to influence spermicide use or pregnancy risk. Expand
Contraceptive Efficacy of a Novel Spermicidal Microbicide Used With a Diaphragm: A Randomized Controlled Trial
TLDR
An acid buffering gel used with a diaphragm is a safe, acceptable contraceptive with efficacy comparable to that of a common commercial spermicide with diaphrate, and safety and acceptability were similar between the two groups. Expand
Effects of Long-Term Use of Nonoxynol-9 on VaginalFlora
TLDR
It is demonstrated that most nonoxynol-9 users experienced minimal disruptions in their vaginal ecology, and there were no differences between the different formulations evaluated with respect to changes in vaginal microflora. Expand
CONTRACEPTIVE VAGINAL SUPPOSITORY CONTAINING nONOXYNOL-9 AND ZINC ACETATE SALT IN A CLINICAL TRIAL
TLDR
A new preparation based on the addition of low concentrations of zinc acetate salt (Zn (OAC)2) to N-9 that reduce the irritation of mucous membranes on frequent use and increase the efficacy of N- 9 is made in the form of vaginal foaming suppository. Expand
Participant characteristics associated with withdrawal from a large randomized trial of spermicide effectiveness
TLDR
Characteristics of participants who failed to complete seven months of planned participation in a trial of spermicide efficacy were explored, finding that failure to complete is a major problem in barrier method trials that seriously compromises the interpretation of results. Expand
Noncomparative Contraceptive Efficacy of Cellulose Sulfate Gel
TLDR
Cellulose sulfate vaginal gel yields pregnancy rates comparable to nonoxynol-9 and few adverse events among couples at low risk for sexually transmitted diseases. Expand
Spermicide used alone for contraception.
TLDR
In the largest trial to date, the gel containing the lowest dose of nonoxynol-9 was significantly less effective in preventing pregnancy than were gels with higher doses of the same agent; the latter threatens trial validity. Expand
Spermicidal and antifertility effects of an imbibing and soluble nonoxynol-9 diaphragm (ISND) in rabbits
TLDR
The spermicidal and antifertility activities of a low dose N-9 in the ISND were high, with properties of imbibition and solubility confirmed. Expand
Bleeding patterns after use of levonorgestrel emergency contraceptive pills.
TLDR
The effect of the single-dose levonorgestrel ECP regimen on the timing and duration of the next menstrual period depends on when during the cycle the pills are taken. Expand

TLDR
The contraceptive effectiveness of these two spermicidal products appeared similar and both products were associated with a fairly high risk of pregnancy in this young, highly sexually active population. Expand
Comparison of the Influence of Spermicidal and Non-Spermicidal Contraception on Bacterial Vaginosis, Candidal Infection and Inflammation of the Vagina—A Preliminary Study
TLDR
Overall results showed that the prevalence of BV in non-spermicide users was 35/113 (31%) but was significantly less in spermicide users, 10/66 (15%), P<0.05. Expand
A Dosing Study of Nonoxynol-9 and Genital Irritation
TLDR
Genital irritation was located primarily on the vagina or cervix, and vulvitis was not a significant problem, and women who infrequently use N-9 products may not experience an increase in genital irritation. Expand
The influence of nonoxynol-9-containing spermicides on urogenital infection.
TLDR
The physician must weigh the risk of exposure to sexually transmitted diseases or an unwanted pregnancy against the prevention of urinary tract infection or vaginal candidiasis before advising the patient to discontinue the use of nonoxynol-9-containing spermicides. Expand

TLDR
The polyurethane condom was not shown to be as effective as the latex comparator condom for pregnancy prevention, however, the risk of pregnancy in the polyUREthane group falls in the range of other barrier methods. Expand

Incidence of Acute Urinary Tract Infection in Young Women and Use of Male Condoms With and Without Nonoxynol-9 Spermicides
TLDR
In this study, use of male condoms was associated with increased urinary tract infection risk; the largest risk wasassociated with exclusive condom use and use of Nonoxynol-9–coated condoms. Expand
Contraceptive efficacy.
TLDR
In this issue of the ARCHIVES, dermatologists prescribe two of the most potent teratogenic drugs, isotretinoin (Accutane, Roche Laboratories, Nutley, NJ) and thalidomide, and try to help patients understand factors influencing contraceptive efficacy. Expand

TLDR
In postmenopausal women, anatomical and functional characteristics of the genitourinary tract are more strongly associated with UTI risk than in younger women, and a genetic predisposition to recurrent UTI is suggested. Expand
Contraceptive failure rates: new estimates from the 1995 National Survey of Family Growth.
TLDR
Levels of contraceptive failure vary widely by method, as well as by personal and background characteristics, and income's strong influence on contraceptive failure suggests that access barriers and the general disadvantage associated with poverty seriously impede effective contraceptive practice in the United States.
