Boys and Girls Quiz Puzzle

In many ancient cultures male children were prized more highly than female children, perhaps from the desire to produce a son and heir. Thankfully this attitude is much less common in this day and age.

One country had a law that married couples who wanted children must continue having children until they had produced a male child, and then they had to stop. If the first child is male - stop there. If the first child is female - keep going until a boy is born.

Assuming a 50% chance of a male child, and thus a 50% chance of a female child, over the long term what is the likely ratio of male to female children going to be?
