title: Biological profile of the steroid 5 alpha-stigmastane-3 beta, 5, 6 beta-triol-3-monobenzoate.
abstract: The steroid 5 alpha-stigmastane-3 beta, 5, 6 beta-triol-3-monobenzoate at a dose of 40 mg/kg/day showed significant antifertility activity when administered orally in a single or in consecutive doses during pre-implantation stage of pregnancy in mice. In the rabbit interceptive activity was obtained when the test steroid was administered on Day 8 of pregnancy in a single dose level. The compound failed to show any distinct estrogenic or androgenic property following bioassay method. But in McPhial test, the compound showed some progestagenic activity.
