how long does sperm live

Sperm is a crucial component in the process of reproduction. It is the male reproductive cell that fertilizes the female egg, resulting in the creation of a zygote that eventually develops into a fetus. However, many people are unaware of how long does sperm live, both inside and outside of the body. In this post, we will explore the lifespan of sperm and factors that can impact their survival.

How Long Does Sperm Live Inside the Body?

Inside the male reproductive system, sperm can live for several days. The exact lifespan of sperm can vary depending on a variety of factors, including the man’s age, health, and the environment inside the body.

On average, sperm can live for up to five days inside the female reproductive tract. This is due to the favorable conditions provided by the cervical mucus and the nutrients present in the female reproductive system. However, the majority of sperm typically only survive for around 48 hours.

It is worth noting that not all sperms are created equal. Sperms can vary in terms of their motility (ability to move), morphology (shape), and concentration (number of sperm per milliliter of semen). These factors can all play a role in how long does sperm live inside the body.


Motility is the ability of sperm to move. Sperms that are highly motile are able to swim through the female reproductive system and reach the egg more easily, increasing the chances of fertilization. However, sperm with low motility may struggle to move through the reproductive system, reducing their chances of fertilizing an egg.


Morphology refers to the shape of sperm. Sperm with abnormal morphology may have difficulty penetrating the egg and fertilizing it, reducing their chances of survival.


The concentration of sperm refers to the number of sperm present in a milliliter of semen. Men with a high concentration of sperm may have a better chance of fertilizing an egg, as there are more sperm available to do so.

Things That Impact the Lifespan of Sperm

As mentioned earlier while learning how long does sperm live, several factors can impact the lifespan of sperm. Some of the most significant factors that can impact a sperms life span include:

Age: Men’s sperm quality and amount may decrease as they get older. This can make it more difficult for sperm to survive inside the female reproductive tract and fertilize an egg.

Health: Certain health conditions, such as sexually transmitted infections (STIs) or hormonal imbalances, can impact the quality of sperm and their ability to survive.

Environment: The environment inside the male and female reproductive systems can impact the survival of sperm. Factors such as pH levels, temperature, and cervical mucus can all play a role.

Frequency of ejaculation: Men who ejaculate frequently may have a lower concentration of sperm in their semen, which can impact the chances of fertilization.

Use of lubricants: Some lubricants can be harmful to sperm and decrease their ability to survive inside the female reproductive tract.

Genetics: Genetic factors can also impact the lifespan of sperm. For example, men with a family history of infertility may have a higher risk of having low-quality sperm.

Lifestyle factors: Certain lifestyle factors, such as tobacco and alcohol use, can also impact the quality and quantity of sperm.

How Long Does Sperm Live Outside the Body?

As we learned about how long does sperm live inside the body it is also important to know about how long does sperm live outside of the body. When sperm are exposed to air, the lack of moisture can cause them to dry out and die quickly. However, in certain conditions, such as in a laboratory or in a test tube, sperm can be kept alive for several days.

Sperm can also survive for a short time on surfaces such as clothing, bedding, or bathroom fixtures. However, the lifespan of sperm on surfaces is highly dependent on several factors, including temperature, humidity, and the presence of substances that can kill sperm, such as certain cleaning products or chemicals.

In general, sperm that are outside of the body are much more fragile and have a much shorter lifespan than those inside the body. This is because they are not in the optimal environment needed for their survival and cannot receive the nutrients and protection they need to stay alive.

How Does Sperm Lifespan Impact Fertility?

Understanding how long does sperm live can have a significant impact on fertility. If sperm are unable to survive for long enough inside the female reproductive tract, they will be unable to fertilize an egg and conception will not occur.

Low sperm count, poor sperm motility, and abnormal sperm morphology can all decrease the chances of fertilization and impact fertility. If a man has a low sperm count or poor sperm quality, it may be more difficult for him to conceive a child with his partner. In some cases, fertility treatments such as in vitro fertilization (IVF) may be necessary to help overcome these challenges.

In addition to male factors, female factors can also impact fertility. Issues such as blocked fallopian tubes or hormonal imbalances can make it more difficult for sperm to reach and fertilize the egg. Age is also a significant factor in female fertility, as the quality and quantity of eggs decrease as women age.


Having knowledge about how long does sperm live is important for individuals who are trying to conceive, as it can help them identify any potential fertility issues they may be experiencing. If you are having difficulty conceiving, it is recommended that you consult with a healthcare provider to determine the underlying cause and explore treatment options.

Finally, it is worth noting that while understanding the lifespan of sperm is important for fertility, it is also important to prioritize safe and responsible sexual practices to prevent the spread of sexually transmitted infections (STIs). Using condoms and other forms of protection can help reduce the risk of STIs and protect both partners’ sexual health.
