Implications of incorrect determination of fetal sex by ultrasound

To assess the experiences of women following incorrect determination of fetal sex by ultrasound.

A 3-year prospective cohort study of 102 women with discordance between fetal sex determined by ultrasound scan and birth sex. Participants were interviewed using 2 structured pretested questionnaires. The first questionnaire was undertaken within 24 h of delivery. The women were followed up with a second questionnaire 6-9 months later. In-depth interviews were also carried out at this time.

Women who had received an incorrect determination of fetal sex by ultrasound experienced marital conflicts, domestic violence, negative perceptions of ultrasound, and a desire for reversal of tubal ligation.

Incorrect determination of fetal sex by ultrasound has implications that can affect the mental and psychological health of the mother and the upbringing of the newborn.
