interceptive

1. (more specifically) Pertaining to the prevention of pregnancy by interfering with the implantation of the embryo in the uterus.Examples: "Our calculations on the relationship between uterotrophic and interceptive activities support the concept that interruption of early pregnancy is one of the properties of an "estrogenic" compound (Carlborg, 1970)."; "The crude petroleum ether, chloroform and alcoholic extracts of the root administered orally at the single dose of 100 mg/kg bw given at the post implantation period showed 100 per cent interceptive activty in mature female mice."; "Since the pregnancy interceptive agents or the menses regulators may also influence the development of either trophoblasts or the maternal cells (epithelial and stromal) at the embryo attachment site, another in vitro assay method using using trophoblast cells of hamster and mouse isolated from a preplacental organelle, the ectoplacental cone, has been developed."not-comparable
