Enclomiphene induces luteolysis in the nonpregnant guinea pig.
The effect of two antiestrogens, enclomiphene and tamoxifen, on luteal function in the guinea pig was compared to that of estradiol, a known luteolysin. Enclomiphene caused premature luteolysis when administered during the early or mid-luteal phase of the cycle, but was not as potent as estradiol. Tamoxifen had no effect. The luteolytic effect of enclomiphene was mediated by the uterus, as has been shown for estradiol.
