I dont know if this helps, but under "Fertility" there is a post about gender selection. It has the Chinese Lunar charts. They seem pretty acurate. There is a link in there for it, or I just typed Lunar Age into a search and it gave me the right links. It is suposed to tell you what months you need to concieve to produce a boy or girl. We tested it on a couple people, and it was right 6 out of 7 times!!! Pretty amazing to me! I am hoping to concieve during Nov or sooner, as it says that is my best chance of a boy until next spring!! HTH!!
