Should non-invasive prenatal testing (NIPT) be used for fetal sex determination? Perspectives and experiences of healthcare professionals

Non-invasive prenatal testing (NIPT) can not only accurately detect early in pregnancy the presence of chromosomal abnormalities but also fetal sex. However, whether fetal sex should be reported after performing NIPT is ethically contentious. In Belgium, NIPT is practically fully reimbursed and offered to all pregnant women as a first-tier screening. In practice, fetal sex is reported upon request of the expectant parents; however, this is not stipulated in guidelines. As more countries are offering NIPT and looking to implement it in public healthcare, challenges and insights of healthcare professionals working in Belgium can be of value for others. We assessed healthcare professionals’ experiences with and perspectives on sex determination and reporting following NIPT in Belgium by conducting a semi-structured interview study. We interviewed 30 professionals involved in prenatal screening. While overall healthcare professionals did not consider reporting fetal sex to be an issue if the expectant parents want to know, some consider the reporting of a non-medical trait like fetal sex problematic when it is reimbursed or if it could lead to sex-selective termination of pregnancy. Moreover, the strong desire of expectant parents to know fetal sex risks compromising informed decision-making about NIPT. In this way, fetal sex may distract from the primary aim of NIPT as a test for medical conditions. Improving pre-test counseling both in terms of quality and availability may help overcome some of these issues.
