Back to Your pregnancy and baby guide. Getting pregnant conception happens when a man's sperm fertilises a woman's egg. For some women this happens quickly, but for others it can take longer.
An important aspect of fertility and pregnancy is sperm, and the lifespan of sperm after ejaculation completely depends on where it's living. How long sperm live depends on where the sperm are deposited. Sperm inside the vagina can live within cervical mucus or the upper genital tract for three to five days, allowing fertilization to occur so long as the sperm are living.
The length of time they stay alive has a lot to do with environmental factors and how fast they dry up. If you ovulate shortly after you finish your period, the sperm may still be alive and can fertilize the egg. Learn more: Can you get pregnant if you have sex on your period?
Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue. Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm.
Hey Summer! This is an incredible feat compared to the brief lifespan of a mere few hours when there is no cervical fluid present. This is why tracking cervical fluid is crucial to understanding your fertility.

Some die within minutes, and some can live anywhere up to seven days, under perfect conditions. But most live about two or three days inside the female reproductive system, according to USC Fertility. You need just one sperm to make it to the right place — the correct fallopian tube — at the correct time — after ovulation — to create a new life.
