Association between placental localization and fetal gender detection early in pregnancy

Abstract

Background: Ultrasound (US) is a highly feasible way to assess fetal health as well as detect the gender to satisfy parents’ curiosity and it is important in several hereditary and chromosomal diseases. Objectives: The aim of this study was to determine the gender of the fetus during the first trimester by detecting the chorionic villi (placental) location by US and finding its relation with fetal gender. Materials and Methods: The study was conducted on 67 women in April 2019–April 2020 on outpatient private clinic, ultrasound machine used DC N3 Pro, transabdominal approach by 5 MHz probe 3C5A measuring transverse and sagittal views of the gestational sac and localizing chorionic villi, another scan was done in the second trimester to identify the fetal gender by visualizing the genitalia. Results: Of 67 pregnant women examined, 40 had male fetuses and 27 had female fetuses. Approximately 50% of males had right-sided placenta. And 50% of them had left sided placenta, 11 out of 27 examined females fetus had right sided placenta, 16/27 female had left sided chorionic villi, Chi square analysis done, P-value was 0.456. Conclusion: The site of chorionic villi has an insignificant correlation with fetal gender difference.
