[Reccurent pregnancy loss - review]. / Opakované potrácení - prehledový clánek.

OBJECTIVE: Informative review of possible causes and therapy of habitual pregnancy loss and infertility. DESIGN: Review. SETTINGS: Department of Gynecology and Obstetrics, General Faculty Hospital of Charles University, Prague. SUBJECT AND METHOD: The repeated (habitual) loss of pregnancy is defined by three or more spontaneous abortions. Approximately 0,4 to 1% of women are affected. The pregnancy loss is more frequent in women younger than 20 and older than 35 years. The frequency of spontaneous abortions parallels the number of previous pregnancies. The causative treatment of women with recurring abortions is not available, however, it is recommended that such women are evaluated by available methods to eliminate etiological causes of repeated pregnancy losses. CONCLUSIONS: Effective therapy is possible when the diagnostic reason for repeated abortions is determined. Nevertheless, the causes leading to repeated pregnancy losses are identified only in approximately 12% of women. However, alleged and unexplained infertility, resulting in habitual pregnancy losses has a favorable prognosis.

Autoimmune antiovarian antibodies and their impact on the success of an IVF/ET program.

In previous papers, we referred to studies of the influence of antiovarian autoantibodies on menstrual cycle disorders in adolescent girls. We examined autoantibodies against ooplasma, zona pellucida, membrana granulosa, theca folliculi interna, and lutein cells. In infertile women in the IVF/ET program, we studied the positivity of antiovarian antibodies and cytokines, namely, TNF-alpha and IL-1 beta, in follicular fluid correlated with the following subgroups, characterized by the outcome of in vitro fertilization, as follows: G, pregnant; F, fertilized; N, nonfertilized; and O, no oocyte gained. The presence of autoantibodies corresponds to the success or failure of the IVF/ET program. Our results support the hypothesis that antiovarian autoantibodies play an important role in both the endocrine and the reproductive function of the human ovary and that it can influence them negatively.
