http://genderdreaming.com/forum/gend...s-swaying.html it explains everything in great depth and supported by actual scientific studies by reputable sources. IG has it quite wrong on when to TTC for pink, and rather inexplicably, they claim that Australia is immune to seasons - um no, your seasons are just the opposite of those in the Northern Hemisphere.
Northern Hemisphere - girl peak conception months Mar, April (best month), May (and possibly to a lesser extent, Feb but maybe June but it is getting too close to summer and longer days for me to totally feel comfy with)
boy peak conception months Sept, Oct (best month), Nov (possibly to lesser extent, Aug; maybe Dec. but is getting too close to winter and shorter days for me to feel totally comfy with)
Southern Hemi - reverse above, so girl peak months are Sept, Oct, Nov (possibly Aug, possibly but less likely Dec)
boy peak conception months Mar, April, May (possibly Feb, possibly but less likely June)
Around the equator, the peaks don't seem to work as well. This is apparently some quirk of living in temperate climates with 4 distinct seasons.
There are plenty of opposites conceived in both girl peaks and boy peaks so obviously first and foremost everyone should do what is best for themselves and their families BUT if you have the option, it makes sense to me to time conception to at least try and capitalize on these peaks.
