How Possible and Interesting it is knowing Your Baby Sex Quite Early.

The Ramzi theory is a strategy for using the location of the placenta during early pregnancy ultrasounds to predict the sex of a baby.
Some people claim on online message boards that the method is as much as 97% reliable.
Proponents refer to a study that involved a large number of ultrasounds. However, that study has not undergone peer review, and Dr. Saam Ramzi Ismail, who put his name to the theory, did not publish his research in a peer reviewed journal.

No major medical organization recognizes the theory as valid, and a 2010 studyTrusted Source in a peer reviewed journal disputes the notion that placental location correlates with sex.
Sex differentiation; the process by which embryos begin developing male or female structures — begins early in development, usually about 6 weeks into the pregnancy.
Proponents of the Ramzi theory argue that this means that it is theoretically possible to detect early indicators of sex well before a mid-pregnancy ultrasound might reveal this information.
The theory began with an ultrasound study of 5,376 pregnant people who had ultrasounds at either 6 or 18–22 weeks of pregnancy. However, just 1,200 participants had both ultrasound scans.
Researchers were able to see the external genitalia in 99% of male fetuses and 98% of female fetuses during the second trimester ultrasound. They found that 97.2% of male fetuses had a placenta on the right side of the uterus during the early ultrasound at 6 weeks, while 97.5% of female fetuses had a placenta on the left side of the uterus.
Drawing on this data, they concluded that a placenta on the right side usually indicates a male fetus, while a placenta on the left side is a sign that a fetus is female. This distinction is the basis of the Ramzi theory.
Many message boards feature stories of people who used the Ramzi method to predict the sex of their baby correctly. Any sex prediction method has a 50% chance of being right, though, so anecdotal evidence is not reliable.
