Sex ratio of spontaneously aborted fetuses and delivered neonates in second trimester.
The author investigated in patient material from 12 years 251 cases involving spontaneous abortion and delivery in the second trimester. The material included 28 sets of twins and one set of triplets, thus the total number of fetuses and neonates was 281. The sex ratio was 136.1, higher than that documented natural sex ratio in the second trimester or at term. The ratio approaches that experienced in cases of perinatal death.
