How much sperm can cause pregnancy? Can a little bit of sperm impregnant a woman?
  • Best Answer
Of course, It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time a man ejaculates he releases nearly 100 million sperm.
Sure thing, even Pre-ejaculate (pre-cum) can also have a tiny bit of sperm in it, so pre-cum may cause pregnancy if it gets into the vagina.
