Definition - What does Ramzi Theory mean?
Ramzi theory suggests that the placement of the placenta in the uterus as determined by early ultrasound can correctly predict the gender of the developing fetus. This early ultrasound can take place as early as 6 weeks gestation which generates a gender prediction far sooner in pregnancy than the average 16-20 week structural ultrasound.
Ramzi theory may also be known as Ramzi method.
FertilitySmarts explains Ramzi Theory
The Ramzi theory is based on the original research performed by Dr. Saad Ramzi Ismail. In this study ,more than 5,000 fetuses were scanned by ultrasound for placental location and gender. In normal fetal development, the genitals develop at around 4 weeks gestation so with ultrasounds performed early in pregnancy, it is nearly impossible to accurately determine gender based on visualization of the genitals.
In this study, ultrasounds were performed at 6 weeks gestation and then again between 18-20 weeks, when gender can be reliably predicted. Ultimately, all fetal genders were confirmed at birth. Using the data collected from the study, it was concluded that at six weeks gestation, 97.2% of the male fetuses had a placenta on the right side of the uterus. For female fetuses, in 97.5% cases, the placenta was found on the left side of the uterus.
Ramzi Theory uses this data to form the conclusion that gender can be reliably predicted during early ultrasound based on the position of the placenta within the uterus. There have not been additional studies performed to confirm or dispute this theory.
