The ability of sperm to survive depends on several things. But the most important thing is where the sperm is located. What if in the uterus, how long can sperm survive? These are the facts, Mother.
The average fertile man in each ejaculation test releases almost 100 million sperm. In fact, all that is needed is one sperm to fertilize one egg. to get pregnant. Other sperm do not succeed in reaching the egg.
According to the RO page, sperm is found in semen, which is the bulk of the fluid during ejaculation. Apart from that, there are also other fluids produced by the testicles, prostate and glands in the male reproductive tract.

How long does sperm last in the uterus?
From the moment of ejaculation, sperm is released into the vaginal canal. Sperm travel to the birth entrance (cervix). In one study, sperm was found in the cervix 90 seconds to 3 minutes after ejaculation.
After passing through the cervix, sperm begins to traverse the uterus. It’s only a few inches away, but it’s a long distance for tiny sperm cells to swim. Researchers believe that contractions of the vagina, cervix, and uterus help sperm cells on their journey. This distance can be covered in less than 10 minutes.
Most sperm ‘fall’ along the way due to vaginal pH and other factors. But thousands of sperm reach the fallopian tubes in a matter of minutes. The successful sperm is what can fertilize the egg if it is present or arrives at a later date.
Traci C. Johnson, MD, Obstetrician-Gynecologist, said that sperm in a woman’s body can live up to 5 days.
“If you are a man and have sex even a few days before your partner ovulates, there is a possibility that she is pregnant,” said Johnson as quoted by WebMD.
However, other opinions state that after ejaculation, sperm can survive in the female reproductive tract for seven days or more while waiting for the egg to arrive.
If ovulation occurs within a few days of unprotected sex, pregnancy is possible.
Biologically, an egg can only survive for about 24 hours after being released from the ovary. This means that if a husband and wife have sex a few days before the couple ovulates, they can still get pregnant.
However, seven days is just a rough estimate. Although some people use birth control calendars to count down the days to ovulation and avoid pregnancy, there is evidence that people get pregnant after having unprotected sex on any day of their menstrual cycle.
That’s why calendar birth control is one of the most unreliable contraceptive methods, causing around 24 pregnancies per 100 people who use this method every year.
How long do sperm survive outside the body?
The length of sperm survival is influenced by various factors. If sperm can survive 5-7 days in the uterus, it is different outside the body.
Reported by Healthline, outside the body, sperm can die quickly when exposed to air. The length of time sperm survive is closely related to environmental factors and how quickly it dries.
Johnson explained, on dry surfaces such as clothing or bedding, sperm will die when the semen has dried.
If sperm is near the vagina and has not dried, there is still a chance of pregnancy. Sperm can still move if it is not completely dry.
Life time of sperm in water
Quoted from Planned Parenthood, sperm can swim, but only when it is in the body. If a man ejaculates in a pool, it cannot make a woman pregnant.
Meanwhile, Johnson said that in water, such as a warm shower or hot tub, sperm will likely live longer because they thrive in warm, wet places.
“But the likelihood that sperm in a tub of water will enter a woman’s body and cause them to become pregnant is very small,” said Johnson.
Is there a way to weaken the sperm in the uterus to prevent pregnancy?
Sperm can enter the fallopian tubes in just a few minutes. The closer to ovulation, the easier it is for sperm to travel.
If you ovulate immediately after menstruation, the sperm may still be alive and able to fertilize the egg.
What if the sperm has entered the uterus, is there a way to weaken it so that it can prevent pregnancy? Sperm that have entered the uterus have not been scientifically proven to be weakened or removed.
In the minutes and hours after intercourse, some fluid from the ejaculate may come out of the sperm. Although some of them may contain sperm, most consist of a mixture of proteins and vitamins from the ejaculate.
Quoting from the Medical News Today page, although anecdotal evidence suggests that there are ways to remove semen or kill sperm from the vagina, there is no scientific evidence to support these claims. Some proposed techniques include:
Urination. Some people mistakenly believe that urinating after sex can remove sperm from the vagina. However, because urine comes out of a small hole called the urethra, urinating after sex will not remove sperm from the vagina. Douching. People may douche to try to remove semen from the vagina, but this is unlikely to work, because the water cannot reach the semen in the uterus. Bathe. The logic behind showering to remove semen is that it will release sperm. However, this will not work, because the water will not reach the uterus.
