Dear Yvonne, How long can sperm last in a woman's reproductive system? -Petra

Dear Petra, On average, sperm can survive up to 5 days when luxuriating in a female's cervical mucus, which is at its richest and 'stickiest' right about the time a woman becomes most fertile. A woman's cervical mucous helps coax the little guys toward the ova. When sperm are not nourished and protected in the survival-friendly atmosphere in a female's vagina, they die anywhere from 30 minutes to 4 hours after release, never to swim again.
