Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid (culture medium) in a lab setting. Fertilization is possible as long as the sperm remain alive — at least five days.

“The best studies show a woman's fertile window is four to five days before ovulation,” Flyckt says. A man's sperm can live for up to a week in a woman's reproductive system, and it takes a little time—roughly six to 12 hours—for that sperm to make its way to where it can successfully fertilize the egg.

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. However, you might not know that these new sperm take about 2 ½ to 3 months to fully mature.

An egg lives for about 12-24 hours after you ovulate, and sperm can live for five to seven days.

But in almost all cases, IUI fertilization will take place in a day or two after the procedure --and sometimes just a few hours later. Sperm can live inside the reproductive tract for as long as seven days. So if for some reason ovulation is delayed, sperm could fertilize the egg up to seven days later.

Sperm cells may live in the human body for two or three days after mating.

Sperm can live inside your body for up to 6 days after sex, waiting for an egg to show up. If you ovulate during that time, the sperm can meet up with your egg and cause pregnancy. Morning-after pills work by temporarily stopping your ovary from releasing an egg.

Getting pregnant Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid (culture medium) in a lab setting. Fertilization is possible as long as the sperm remain alive — at least five days.

Sperm cells can survive outside the body, as long as they stay in a warm and wet environment. In other words, semen can still contain live sperm cells until it dries. According to the American College of Obstetricians and Gynecologists, sperm cells may survive inside the female body for 3–5 days after ejaculation.

It's estimated ejaculate contains up to 280 million sperm cells. And under ideal conditions, sperm actually live for several days once inside the reproductive tract. Any unprotected sex you have within about 5 days of ovulation may leave enough sperm waiting and ready to fertilize.

It takes about three months for sperm to mature. Men who quit at least three months before conception will have much healthier sperm with a greater chance of fertilising an egg, and creating a healthy baby. If women quit: Quitting improves the chance of getting pregnant.

Sperm may be damaged by chemotherapy or radiation therapy. Those sperm should be replaced in 2 years. Even if a child is conceived soon after treatment ends, there is no research showing that he or she will have a greater risk of developing serious health problems.

After ejaculation, sperm can live inside the female body for around 5 days. The fluid in a woman's reproductive tract has all of the nutrients that sperm need for their survival during that time.

When considering conception, it is also important to optimize the numbers of sperm available to reach and fertilize the egg. In this effort, it is recommended that men abstain from ejaculating for 2 to 3 days. Men who ejaculate more often have lower volumes of ejaculate and lower sperm counts in each ejaculate.

Step 3: Trigger shot Doctors administer this hormone to help time insemination—they want sperm to be waiting for the mature egg (an egg survives for only 12 to 24 hours post-ovulation, while sperm can live in the Fallopian tubes for days).

Sperm take about three months to mature. This is why quitting at least three months before trying for a baby is important to make sure the sperm is healthy when the baby is conceived.

Luteal Phase Following ovulation, the egg is viable for 12-24 hours, after which it will degenerate if it is not fertilized. Sperm, however, can live inside the female reproductive tract for up to 5 days.
