Treatment with different antiestrogens in the neonatal period and effects in the cervicovaginal epithelium and ovaries of adult mice: a comparison to estrogen-induced changes.

Female mice of the NMRI strain were treated for the first 5 days after birth with the following compounds: diethylstilbestrol (DES), MER-25 (ethamoxytriphetol), tamoxifen, ICI 47.699 (the cis-isomer of tamoxifen, an estrogen agonist), clomiphene, nafoxidine or 17 beta-estradiol-3-benzoate ( E2). Females were killed at 8 wk or 6 mo and, in the case of tamoxifen also at 12 mo. The cervicovaginal region and the ovaries were prepared for histological studies. MER-25 had no effect on either the cervicovaginal epithelium or ovarian histology. Tamoxifen, clomiphene and nafoxidine resulted in extensive regions with a heterotopic columnar epithelium (HCE) in the cervicovaginal preparations. At 8 wk these regions were more widespread than those observed after treatment with DES and E2. While earlier studies have shown a progressive development of DES-induced HCE, that induced by the antiestrogens regressed with time. All ovaries from adult females treated with DES or E2 lacked corpora lutea. For the antiestrogens there were ovaries with or without corpora lutea, and this treatment was not incompatible with fertile females. It is concluded that in the neonatal period, the cervicovaginal epithelium is more sensitive to antiestrogens than central structures (hypothalamic nuclei), but for DES the opposite is true.[1]
