The correlation between a positive fern test and the production of small-for-dates babies


E.S. Theron

Abstract

A group of pregnant women whose cervical mucus gave a positive fern test were compared with a control group with regard to the production of small-for-dates babies and other possible indicators of placental insufficiency. No correlation was observed between the ferning phenomenon and small-for-dates babies or placental insufficiency. In additional observations it was noted that babies with birthweights below the 10th percentile on the Colorado intra-uterine growth chart were in 45% of cases born to mothers showing no weight gain in the last weeks of pregnancy.
