what do i need to do to conceive a boy, i already have a girl?

Only PGD done with IVF can determine sex selection...

Sperm sorting is somewhat good, everything else hasn't been shown to be of any benefit, irrespective of what one may hear or read

Im not sure if this works but it did for my sister. So im not gonna promise you but there is such thing as the boy girl chinese calendar all you have to do is look at the chart for your age and then what month is blue it'll be a boy that you concieve and pink is a girl just google girl boy chinese calendar and you can fing information and the chart!!!! Hope I helped....

this chart worked for 2 of my friends! i didnt use it to conceive but when i looked up the month i conceived and age it said i would have a boy and i am!! sorta freaky!

are you doing OPK's ? i had sex 4 days leading up to when i expected my + opk. on day 5 i got my +OPK and had sex that night also. they say you ovulate 24 to 36 hrs after getting a + OPK, so i had sex before i actually ovulated and conceived a boy! best of luck to you!!!
