Lol at previous posts!
I just copied this from some website:
"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."
I still have no clue!!
