I. M. Lvov. Narrowing of the external opening of the cervix and its improvement in a simplified way Borissowicz'a. (Weekly, 1894, No. 29, p. 485)

Making a brief outline of the pathology of narrowing of the cervical drip, the author points out the narrowing of the external opening, as a common cause (96%) of infertility in women and as a cause, together with inflammatory changes in the neck, painful months. When reducing the contraction, the author often resorts to cutting the neck (Sims) and praises this method.
