I'm sorry, Booth. I really like you. But did you know that 28.8 million sperm in 3 mL of ejaculate actually makes you sterile? The cut-off mark is 20 million sperm per mL. Brennan should have known this, as should have everyone else at the lab.

(And because I know not everyone has medical books filling their libraries, it's simple, Wikipedia is a great source on the fly... .)
