What's the rate of sperm production? Your testicles are constantly producing new sperm in spermatogenesis. The full process takes about 64 days. During spermatogenesis, your testicles make several million sperm per day — about 1,500 per second.

Pregnancy doesn't start the day you have sex — it can take up to six days after sex for the sperm and egg to join and form a fertilized egg. Then, it can take three to four days for the fertilized egg to completely implant itself in the lining of the uterus.

Although the average time is 74 days, the actual time frame for an individual to make sperm can vary. The body produces an average of around 20–300 million sperm cells per milliliter of semen.

Full recovery time is about eight to nine days for many people. Keep in mind this may vary depending on your individual perception of pain and ability for tissue healing. It will take longer until you can ejaculate without sperm in your semen.

Men still get a normal erection, have a climax, and fluid (semen) still comes out. However, after a period of time – usually about two months – there is no longer any sperm present in the semen that is ejaculated.

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.

The Egg Travels to the Fallopian Tube After the egg is released, it moves into the fallopian tube. It stays there for about 24 hours, waiting for a single sperm to fertilize it. All this happens, on average, about 2 weeks before your next period.

The Sperm's Long Journey A man may ejaculate 40 million to 150 million sperm, which start swimming upstream toward the fallopian tubes on their mission to fertilize an egg. Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours.

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.

In order for pregnancy to happen, sperm needs to meet up with an egg. Pregnancy officially starts when a fertilized egg implants in the lining of the uterus. It takes up to 2-3 weeks after sex for pregnancy to happen.

Once the sperm is DRY it is dead and cannot travel to fertilize an egg. Sperm can live for 3-5 days if it is in a warm, moist environment such as the vagina or uterus of a woman. Sperm cannot come back to life once it has dried, even if it is pre-moistened.

When sperm are inside a woman's body, they can live for up to 5 days. If you're a man and you have sex even a few days before your partner ovulates, there's chance she may get pregnant.

After you ovulate, your egg stays in the fallopian tube for 12 to 24 hours waiting to be fertilized by one of the 250 million sperm (on average) that your partner ejaculates during sex.

Taking into account how long sperm survive and the time it takes for fertilization and implantation, you can be pregnant as soon as seven days after you had sex or as long as 15 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.

It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl.
