Anovulation and oviductal hyperplasia in rats treated with clomiphene citrate 5 days after birth.
Five day old female rats were administered either 500 micrograms clomiphene citrate or propylene glycol. Vaginal opening occurred significantly earlier in the clomiphene treated group as compared with the control group. Clomiphene treated rats showed permanent sterility associated with anovulatory vaginal cycles in which the stage of vaginal cornification predominated. Furthermore, clomiphene treated rats exhibited a high incidence of pyosalpinx (or oviductal abscess). The possible mechanisms responsible for the anovulatory sterility and the pyosalpinx induced by neonatal clomiphene treatment are discussed.
