The aim of the study is to evaluate the results of tests performed in "infertile" couples that have obtained spontaneous pregnancy. 953 couples were studied from 1986 to 1991; 108 spontaneous pregnancies occurred (11.1%). All patients were evaluated according to standard procedures recommended by literature. "Female factor" as cause of infertility was present in 41.5%; "cervical factor" was present in 19.4%; "male factor" was present in 48.1% while in 14.8% of the couples evaluated no pathology was showed. In this series, spontaneous pregnancy occurred within 4 year of infertility in more than 90%; no significant difference was present between primary and secondary infertility. A considerable incidence of pathologies was observed in couples that obtained spontaneous pregnancy. Our data suggest that common investigation for infertility may have not a real prognostic value.
