logical deduction - The barbarian king



A barbarian king wants his tribe to have more men than women, because men can fight and women cannot. to achieve this, he introduces the following law:



Each couple has to produce babies until they have at least one boy. Then they must stop producing babies.



By doing this, he ensures that every couple has a boy, and some couples will have zero girls.



But his councillor sees a flaw in this plan. He says that to have more boys than girls he needs to make the opposite law.



Each couple has to reproduce as long as they get boys. When they get a single girl, they have to stop.



By doing this, some couples will get many boys, and none will ever get more than one girl.


Which law would get the most boys?


Note: The barbarian king does not care about the total number of babies. He just wants more boys than girls.
