Spontaneous pregnancy in “sterile couples”

Abstract
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.
