Optimal body fat percentage for getting pregnant

Do any of you know what the lower limit of body fat percentage is in order to get pregnant? I'm not talking about BMI (my BMI is significantly higher than my body fat percentage measured by a Bod Pod). I'm trying to look it up online but I'm only seeing info about BMI. Thanks!!! If it helps, my body fat percentage is 16.4% while my BMI is 23.6.
