It seems that if the placenta is on the left, there is a high chance of having a girl, and if it is on the right, a high chance of having a boy.
"Material and Method
This is a multi-center prospective cohort study of 5376 pregnant women that underwent ultrasonography from 1997 to 2007. Trans-vaginal sonograms were performed in 22% of the patients at 6 weeks gestation, and Trans-abdominal sonograms were used at 18-20 weeks gestation, at this time the fetal gender were confirmed in 98-99%. The fetal sex was confirmed 100% after delivery. The study also addressed the bicornuate uteri with single pregnancy in relation to placenta / chorionic villi location. The result was tabulated according to gender and placenta / chorionic villi location. Bicornuate uteri with single fetus in different horns were studied and tabulated
Dramatic differences were detected in chorionic villi / placental location according to gender. 97.2% of the male fetuses had a chorionic villi/placenta location on the right side of the uterus whereas, 2.4% had a chorionic villi/placenta location to the left of the uterus. On the other hand 97.5% of female fetuses had a chorionic villi/placenta location to the left of the uterus whereas, 2.7% had their chorionic villi/placenta location to the right side of the uterus.127 cases were found to involve bicornuate uteri with single foetuses, most male fetuses were located in the right horn of the uterus and showed right placental laterality (70%). Most female fetuses 59% on the other hand, were located in the left horn and showed left laterality (59%).Moreover, most of the males located in the left horn exhibited right laterality (89%). Also most females located in right horn exhibited left laterality (976.4%). In addition this research indicated that there was a possible link between renal pyelectasis and placental location, and it might be used as a genetic soft marker.
Ramzi’s method is using placenta /chorionic villi location as a marker for fetal gender detection at 6 weeks gestation was found to be highly reliable. This method correctly predicts the fetus gender in 97.2% of males and 97.5% of females early in the first trimester. And it might be helpful to use as a genetic soft marker in relation with fetal pyelectasis."

Talking to an obgyn about this, it's got a high percentage chance, but unfortunately without asking the tech at the scan exactly what side it's on, the pictures can be misleading as the techs turn and manipulate the wand thingy in all different directions. What appears left could be right, etc. I asked my doctor what side the placenta was on and she said 'at the back' that helped rofl.
Saying that though, my sons placenta was on the left and he's defo a boy! x Gosh I wish there was a sure fire way to guess with 100% accuracy. lol
interesting! I cant wait to use all these theorys to guess my babies sex. They will be recording it on a DVD so i can test every theory. Just 9 more days till my scan! Congrats on your baby! Boy OR Girl!
