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.

Before we talk about how to calculate your fertility window, it might be helpful to briefly review the stages of your menstrual cycle , as hormonal changes that occur during the different phases set the stage for ovulation and provide clues as to when ovulation is coming. As you may already know, in order for conception to take place, at least one healthy and vigorous sperm must be waiting in the fallopian tube at the moment ovulation occurs and must be able to fertilize the egg within hours of the egg being released from the ovary. Since sperm can only live for a maximum of 5 days in the female reproductive tract, only a small number of sperm will even survive the long journey through the female reproductive tract.
You had probably assumed, like so many of us, that once the sperm are ejaculated, they have a very short lifespan in which they must win the race to the egg. The egg on the other hand can only survive for up to 24 hours after its release ovulation. So, having sex up to 5 days before the egg is released ovulation can lead to conception. A woman can calculate the day that she ovulates so that she knows when this fertile window is. Check out cyclesavvy to find out how to identify your fertile window.
