Re: is there one?
No there are no test to tell whether a guy is more likely to produce girls or produce boys.
Gratned one can increase one's chances of a certain sex but it requires quite a bit of work and knowledge of the female's cycle. You see sperm come in two ways boy sperm which are faster but die quicker and then there are girl sperm which live longer but are slower. Now the theory is if one has sex the day of ovulation then there are higher odds the baby will be a boy. But if a couple have sex a couple of days prior to ovulation then the odds are in favor of a girl baby. This isnt set in stone....in other words one can have sex on the day of ovulation and still have a girl. It all comes down to what sperm gets there first.
