This randomized crossover trial compared the breakage and slippage rates, safety, and acceptability of the recently developed polyurethane bi-directional eZ·on™ condom with a marketed latex condom. Three hundred sixty couples were asked to use 4 eZ·on condoms and 4 latex condoms. Like several...
Desogestrel (DSG) is a less-androgenic progestogen than levonorgestrel (LNG). This difference in androgenicity may be responsible for observed differences in metabolic effects between oral contraceptive (OC) formulations containing almost equivalent estrogen doses but with either DSG or LNG as a...
Centchroman (Ormeloxifene), a non-steroidal oral contraceptive, is used at a dose of 30 mg once a week. To prevent failures in the beginning of the therapy, it is recommended that a dose of 30 mg twice a week for 12 weeks be administered to build up adequate blood levels. The present study was...
