Ya Ya is expected to reach sexual maturity later this year, meaning the earliest that she and Le Le could mate would be next spring, Brady said. He added that the zoo would give the pandas some time, perhaps two or three years, before resorting to artificial insemination.
Brady said he was loath to make any promises. After all, the pandas, who are from different parts of China, can smell and see each other through cage doors, but they have not been formally introduced yet.
