Knowing that sperm live for 3—5 days in the female reproductive system, for example, means you could have sex several days before your partner ovulates and still result in a pregnancy. One widely believed myth is that sperm only survives for a very short time. Studies show that the average length of time that sperm live, once ejaculated or inserted into the female reproductive system, is around three days. This depends on where she is in her menstrual cycle, however—with just the right timing, stronger sperm could last up to five days. A lot depends on the consistency of cervical mucus.
