Birth Control Pills & Sperm Count: Impact on Effectiveness

Question
More specifically, I was wondering if a large amount of sperm can offset the effectiveness of the pill?

Such as a man (or men, I guess, for the more active ladies) ejaculating several times inside a woman within a short amount of time (such as twice or even 3 times in one day).

Or maybe if they usually just ejaculate a large load each time...

Could too much sperm make birth control pills have a greater chance of failing?

Answer
There are already many million sperm from an ejaculation.  More sperm, even 2-3 times as many would not decrease the effectiveness of the pill.  The pill works mostly by preventing ovulation.  That means there is no egg to fertilize.  With no egg, there is nothing for the sperm to do.
