Here is a link to the Ramzi article:
The Relationship Between Placental Location and Fetal Gender (Ramzi
The article is pretty dense and has a lot of information that doesn't pertain to us in the beginning. Basically, the gist is that the side the placenta is on will help determine gender. In women with a 'normal' uterus, 97% of girls will have the placenta on the left, while 97% of boys will have the placenta on the right. In people with a bicornuate uterus, this number was slightly reduced, but not much. This theory suggests that the egg will most likely implant on the left if it is a girl and on the right if it is a boy, regardless of which side you ovulated on. So according to this theory, side of implantation (likely site of placenta development) means more than the side from which you ovulate.
It sounds as if there is much debate about the validity of this in the medical field, and I don't know if the study has been replicated with the same findings, to date. However, they have a very large sample size (over 5000) and I personally want to believe it because I ovulated from the right and felt implantation very strongly on the left. :)
