It worked for my husband and I when trying for our son back in 2008. If you do it correctly to the book then you have a 85% chance of conceiving a boy.
The shuttles method is a way to choose the sex of your baby. If you want a boy you should try as close as possible to ovulation. For a girl try days in advance of ovulation. Also to do a few other things.
What's the shuttles method?
i tried the shuttles method and it does work. I'm going to try it again this cycle. If anyone needs any pointers in selecting the gender of their child, don't hesitate to ask
