- Determining fetal gender at 6 weeks with chorionic villi or The Relationship Between Placental Location and Fetal Gender Ramzi Ismail, Saad
Robin Elise Weiss wrote about really interesting research that found that you can actually determine the gender of the fetus at 6 weeks! It's called the Ramzi's method. In using this data, Dr. Ramzi Ismail concluded that at six weeks gestation, 97.2% of the male fetuses had a placenta or chorionic villi on the right side of the uterus. When it came to female fetuses, there were 97.5% of the chorionic villi or placenta on the left side of the uterus. Robin writes,
"This is amazingly accurate and has nothing to do with actual visualization of the sex organs, which is impossible this early in pregnancy. Parents want to know the sex of their baby for many reasons, including to figure out how to manage a pregnancy when there may be certain sex linked diseases complicating it. Though the author encourages this to be used as a soft marker to be used between the physician and patient when earlier knowledge can help the team with decision making.
The biggest advantage here is that the use of 2D ultrasound does not pose the risks that other methods do to the pregnancy. It can also easily be incorporated into the first trimester screenings and the results are immediately available. This can also prevent the waiting times that can cause much anxiety for families.But she cautions that "it would be wise not to make decisions that are irreparable because of this knowledge. I'm not even sure if I'd paint a nursery with this answer."
Though this is not widely used anywhere currently, parents wishing to know the sex of their baby may be trying to figure this out any way. If you have an early ultrasound and are not trained, you may misinterpret the results, even if you can clearly see the screen. You would be better off asking the person doing the ultrasound which side the placenta is on, than trying to guess yourself."

This research is begging for follow-up studies. What do the maternity staff thing Baby Friendly means? Why do they think they are or they aren't BF? Why are IBCLC's only correct 89% of the time in knowing if their hospital is BF?
