title: Spermicidal activity of the crude ethanol extract of Sedum praealtum in mice.
abstract: Ethanol extract of Sedum praealtum in intravaginal doses of 10, 20, 40, 50, 100 and 150 mg/kg body weight showed a toxic effect in spermatozoa viability after 24h of administration. Spermatozoa viability was 94, 83, 58 and 24%, respectively, for extract doses of 10, 20, 40 and 50mg/kg body weight, while only dead spermatozoa were found in the vagina of the treated female mice with doses of 100 and 150 mg/kg body weight.
