How long do sperm live (and where exactly)

A lot of people are curious about the lifespan of sperm and their place in the body. It may be crucial for people attempting to conceive or avoid getting pregnant to comprehend this.

Sperm can live for varying lengths of time in different environments, depending on those conditions. For instance, sperm don’t survive very long outside the body and quickly dry up. Under the correct circumstances, they can survive for several days inside a woman’s reproductive system.

Making educated decisions about fertility, timing, and family planning can be aided by knowledge of the locations and duration of sperm life. Let’s examine these specifics to learn more about how sperm work.

How many days does sperm live

The lifespan of sperm depends on environmental conditions. In a woman"s body, sperm can live up to five days. This means that you can get pregnant if sexual intercourse took place 5 days before ovulation. Ovulation occurs approximately 14 days before the start of the next period. If the cycle lasts 28 days and ovulation occurs on the 14th day, then sexual intercourse on the 9th day of the cycle can already lead to pregnancy. Just imagine that you carry live sperm inside you, which are waiting for ovulation in your body for several days. You go to work, take them with you on the subway, wash dishes or play sports, and they are waiting. Amazing.

Outside the body, sperm can live in seminal fluid maximum 24 hours. Semen protects them from drying out, allowing them to last longer. But the exact duration of their life depends on factors such as humidity, temperature and pH. Normally, the pH value of sperm fluctuates between 7.2 and 8.0, which means that it is slightly alkaline. Too low a pH can shorten the lifespan of sperm. Therefore, the pH value of sperm can directly affect the lifespan of sperm. But in the air, for example, on clothes, underwear or on the body, sperm survive only a few minutes. As soon as they stop moving freely in the seminal fluid, they dry up and die.

Where do they "live" sperm in a woman"s body

After intercourse, sperm enter the vagina. Cervical mucus inside the vagina helps them move further. Nature is very smart in this sense, it is at the moment of ovulation or shortly before it that there is a lot of cervical mucus, and its liquid consistency helps the movement of spermatozoa. From the vagina, spermatozoa pass through the cervix and end up in the uterus. And from there they move to the fallopian tubes, where the fertilization of the egg occurs. Studies show that spermatozoa reaches the fallopian tubes within one minute After ejaculation! And here, in the fallopian tubes, they are waiting for a meeting with an egg up to 5 days. It is in the fallopian tubes, and not in the uterus, as is often asked on our forum. It also explains why pregnancy is impossible if the fallopian tubes are impassable or removed.

And if sperm flows after sexual intercourse?

A short answer: it does not play any role. Firstly, It always flows! Secondly, seed fluid arises. Seminal fluid consists of only 10% spermatozoa. The rest is a liquid with proteins and vitamins. Figuratively speaking, seminal fluid is a vehicle for sperm. Without it, they would not be able to "exit" from a man. Getting into the vagina, sperm "transfer" to another vehicle, cervical mucus. And the "old" is poured out as unnecessary. Always. One popular pregnancy planning tip is that lying down and elevating your legs after intercourse will increase your chances of getting pregnant. This is not true. A 2017 study of nearly 500 women who underwent artificial insemination (AI) found no benefit from lying down 15 minutes after the procedure. Moreover, 40% of women who stood up immediately after the procedure got pregnant. And only 32% of women who remained lying down after the procedure.

Depending on their environment, sperm have different lifespans. They have a good window of time to fertilize an egg because they can live for up to five days inside a woman’s reproductive system. Sperm exposed to air outside of the body typically perish within minutes, though under certain circumstances—such as in semen or a warm environment—they may survive a little longer. It’s critical to comprehend sperm longevity for family planning and fertility awareness.

What affects sperm lifespan?

The lifespan and quality of sperm is primarily affected by the pH value of sperm. It usually ranges between 7.2 and 8.0. A low pH can shorten the lifespan of sperm and impair their viability. If your partner has a low pH in the spermogram, then intercourse should be as close as possible to the days favorable for conception. The less time passes between sexual intercourse and ovulation, the higher the chances of conception. Unfortunately, there are no special drugs that can increase the lifespan of sperm. However, measures such as a healthy diet, a balanced lifestyle, and avoiding harmful environmental influences can generally have a positive effect on sperm quality.

Location How long sperm live
Inside the female body Up to 5 days
Outside the body (e.g. on skin or surfaces) A few minutes to an hour
In water (e.g. a bath) A few seconds to a few minutes
In a lab (e.g. stored for fertility treatments) Several years when frozen

Depending on their environment, sperm have varying life spans. Under ideal circumstances, sperm can live up to five days in a woman’s body, particularly in the cervical mucus. Sperm normally only survive a few minutes or hours outside the body before drying out and losing their ability to swim.

Whether you’re trying to prevent pregnancy or conceive, it’s important to know how long sperm can live. The fact that sperm are most viable in environments that are healthy and conducive to their development is also helpful, as overall reproductive health is crucial.

Making informed decisions regarding fertility and sexual health is facilitated by having knowledge of these facts. Gaining insight into the internal and external behaviors of sperm can help you better manage the timing and expectations surrounding conception.
