title: [Ultrastructural study of dysgeneic ovaries of rats, resulting from Misulban administration during fetal life].
abstract: She-rats have been treated at the 15th day of gestation with Misulban. The she-rats born from the former ones present an ovarian dysgenesis due to a precocious destruction of the germinal cells by the radiomimetic. These dysgeneses are characterized by the presence of cordal epithelial structures and of stroma. Cells whose cytoplasmic infrastructure is characteristic of a steroidogenesis have been searched on ovaries taken of between 15 days and 6 months. In the absence of follicular organization, they appear only from puberty and are localized particularly, between the epithelial structures, in the conjonctive stroma.
