Dysfunctional endometrium in primary and secondary sterility. An optic and electronmicroscopic study.

Endometria from women with primary and secondary sterility were morphologically, optically and ultrastructurally studied; such endometria were selected by clinical and paraclinical methods. In dysfunctional endometria the most important modification consists in the perturbation of the cyclical maturation process of the epitheliostromal components, perturbation which may take place "synergically" or it may be "dissociated", in disagreement with the theoretic day of the menstrual cycle. Such perturbations took place in varied circumstances: "out of phase", luteal deficit associated with hyper- or hypoestrogenemia, or pure luteal deficit, receptivity disorders, association with specific or unspecific inflammatory lesions, anovulatory cycle. Endometrium biopsy constitutes the best method for the diagnosis of endometrial dysfunctions, showing both the ovary's global hormonal function, and the qualities of the endometrial receptor, with the corrective of the corresponding technical processes and the compulsory knowledge of some clinical data.
