Hi Rosa , I think there's a much higher power than you and I that decides such things . Be happy your daughters are healthy and happy girls . Perhaps one day they will be blessed with a Brother .
Don't know how true this is but I have a friend who has four girls and they were told that the husband didn't produce enough testosterone to make a boy.
you need this info - "How to choose the gender of baby":
I spent 30 years in OB/L&D: sperm for males swim fast but die off quick, sperm for females are slower swimming but survive longer. Thus, if you time intercourse with ovulation, abstaining the week prior to ovulation, you will increase your odds of having a boy.
Of course, that really begs the question of how many children one SHOULD have with the current world population overshoot... if trying to swing the odds in favor of one or the other, this should help.
any other questions... email me from....
