The gender of the fetus should be included in the prenatal ultrasound – echocardiographic examination reports in tertiary centres in 2021 – recommendations from the Polish Prenatal Cardiology Society

The following paper is a review of research and a summary of the latest publications concerning examples of fetal sex congenital defects and their diagnostic problems with the assessment of the need to focus on fetus gender in prenatal ultrasound exams in referral centres. Determining the sex of the fetus may be of fundamental importance. However, so far it has been recommended only in Danish and Scandinavian guidelines. Defects of the genitourinary system are identifiable in prenatal tests and can coincide with other defects, including not only abdominal defects but also heart defects. Functional disorders within the external genitalia may be a clinical manifestation of heart failure and ongoing intrauterine infections. On the basis of the currently available research studies in the field of perinatology and paediatrics, we came to the conclusion that the determination of fetal sex should be carried out each time in prenatal ultrasound examinations at the reference centre.
