How Long Can Sperm Survive in a Condom

For pregnancy to occur, sperm must find its way inside a woman's vagina while she'due south fertile—but can sperm survive outside of the body? Can y'all become meaning from semen on easily? What if yous wash your hands? Your bed? A toilet?!? Given that pregnancy is a pretty large deal, these are pretty important questions to know the answers to, and all the above swivel on the viability or lifespan of sperm in diverse situations.

Sperm Viability at a Glance:

As well long? Don't want to read all that? Below you'll find the quick answer for each situation. Note that on all surfaces outside the body, semen should be considered capable of causing pregnancy until dry. The time frames given below are estimates based on probable drying times. Dry semen can't cause pregnancy.

Inside the male body: 42 to 76 days, 3 to 5 days of which sperm is mature, and up to four.5 hours in the urethra.
Within the female body: Upwardly to 5 days, with the first 48 hours being the most feasible.
On skin near genitals: Effectually an hr.
On skin elsewhere (such as hands): Around 30 to 40 minutes.
Subsequently washing hands, rinsing, or in h2o: H2o volition destroy sperm when outside the body.
On fabric: A few minutes.
On hard surfaces: Depends on the surface temp, a few minutes to hours.

How Long Do Sperm Alive Inside the Body:

Inside the male body:

This is actually a trickier question than you'd await. It takes between 42 and 76 days for a single sperm to mature, and the boilerplate male makes about ane,500 sperm per 2nd. However, mature sperm only alive for 2 to 5 days before they're broken down and recycled by the body, and then to speak.

This means, technically, sperm live in the male torso for months, just they are but viable in the body for a few days. Regardless, sperm are produced at a constant charge per unit, pregnant there are always feasible sperm in a male's body, assuming functional reproductive health.

Likewise note that while age slows down the rate of sperm production, information technology doesn't stop it—the oldest man to father a child was 102 years old! Likewise, because there is this continuous bicycle of product and recycling, the body doesn't really store sperm. Semen, the fluid sperm are carried within, is produced fresh at each ejaculation, and the sperm present range from newly mature to a few days old.

Afterwards ejaculation, sperm can also remain viable in the urethra for up to iv.5 hours. This is one reason when practicing the pull-out method, urination is recommended between acts, though as it'due south unknown if this is the only method past which sperm can make their way into precum, this may non ever exist effective.

Inside the female torso:

The lifespan of sperm inside the female person body is generally accustomed at a max of 5 days, with the outset 48 hours being the nearly viable. However, some research has as well suggested this fourth dimension frame may vary from adult female to adult female and even bike to cycle. For example, it's suggested that intercourse closer to the commencement of a woman's cycle shortens the viability of sperm due to less favorable vaginal pH. This implies that the closer to ovulation the sex occurs, the more likely sperm could survive longer in the female body

How Long Do Sperm Live Outside the Trunk:

On your skin near genitals:

Sperm viability outside the trunk depends on quite a few factors, but the jest of information technology is, once the sperm dries out or is otherwise damaged, it can no longer cause pregnancy outside of assisted reproduction. This means that the more platonic the conditions where the semen was deposited, the longer sperm can survive. Information technology's besides important to note that oxygen does not kill sperm. Rather the drying factor of air eventually leads to sperm becoming permanently immobile.

The ideal conditions for sperm are about 93 degrees (slightly beneath body temperature, much like that of the testicles) and moist with a pH around 7 to viii. However, semen sample lab instructions often suggest room temperature is ideal in cases where storage time is less than one hour.

The genital area tin check all these boxes. In females, the vulva area unremarkably runs around 91 to 93 degrees with a skin pH effectually 5 to vi (dry) and is naturally moist. The penis area runs between 93 and 89 degrees (ranging from base of operations to glans), also with a pH of v to six. These temperatures are affected by surrounding temperature and activity level (in a hotter room or during the commonly agile human action of intercourse, both would exist warmer).

Equally a issue, sperm is more probable to remain feasible near the genitals than elsewhere on the body. Unfortunately, simply how long would depend on how much semen was present (to slow dry out fourth dimension and alter skin pH) and how close it was to the genital area (where pare temp is typically a bit college).

To requite a rough idea, in a new technique used to air-dry sperm for assisted reproduction (again, dry sperm can't cause pregnancy exterior of a lab), semen placed on a drinking glass lab slide and heated to 98.6 degrees dries in 25 to 30 minutes. While this is internal body temp, the surface of your skin, even in the genital area, is, as mentioned, a bit cooler than this, and likewise moist not a glass slide with a thin smear. Given this, bold y'all don't wipe the semen off, semen may remain viable upwards to an hour or and so near the genital surface area.

On your peel elsewhere (Such as on hands):

Not only do other parts of your body have a lower temperature, but they also tend to be far drier and may comprise trace contaminants (such as soap residue or balm) that would shorten the survival of sperm. For case, your hands run between near 87 and 90 degrees only cool more proportionally to the surrounding temperature. They are besides dry out. As a result, sperm on more than exposed pare like this would dry closer to the rate of the slide mentioned above, at around 30 to twoscore minutes.

Regardless, information technology's of import to proceed in mind that the probability of pregnancy from sperm on easily or other skin when not nearly the vagina is uncommonly low. For one, most would non let semen merely sit on their easily or skin to dry. Washing off semen, even with just water, is sufficient to destroy whatsoever sperm present due to osmotic shock. Too, wiping dry will transfer whatever sperm to the detail used.

Side note, or more cautionary advisement, h2o volition not kill sperm that are already inside the body. Washing a vagina with water or having sex in water (if ejaculation occurs within the vagina) will not lower the chances of pregnancy.

Back to the topic at paw, for perspective, the boilerplate ejaculation contains 200 to 500 meg sperm, just even when ejaculated into the vaginal canal, many sperm are lost as they make their way through cervical mucus, the cervix, uterus, and Fallopian tubes to an egg. In fact, merely a few hundred or approximately .01 pct find their way to the egg, and even and so, fertilization and implantation only succeeds about 25 percent of the time. The chances of a few stray sperm from, say, your easily, resulting in pregnancy is and so astronomically low unless fresh, visible semen was inserted.

On textile surfaces (wear, towels, blanket, etc.):

Equally fabric will absorb wet from semen, drying fourth dimension is reduced. Fabric is likewise rarely of a proper temperature to support the survival of sperm. Given this, sperm volition only live a few minutes on cloth unless the cloth is saturated to the point moisture tin can be felt (soaked). Note that sperm also require a medium (such as semen or cervical fungus) to remain motile, so no, they tin't 'swim' through wear, unless again, the fabric is so saturated a medium is still present.

In open air on a hard surface:

Every bit mentioned, on a hard glass slide at 98.vi degrees, semen will dry in well-nigh 25 to 30 minutes. At room temperature (closer to lxx degrees), this would be slower. For instance, semen samples typically liquefy for examination within xv minutes at room temperature (liquefaction would be a step before drying)—anything over threescore minutes is considered abnormal. This would imply that the drying time (then survival time) of sperm on hard surfaces such as a toilet seat is highly variable depending on temperature, probable ranging from minutes to an hour. None the less, the chances of pregnancy from such a situation are virtually not-existent.

In water (shower, tub, pool, etc.):

As mentioned earlier on this folio, sperm will quite literally explode due to osmotic shock within minutes of exposure to water if the protective layer of semen is done abroad. Again, note that this does non utilise inside the body, practise non endeavour to preclude pregnancy by 'washing' sperm out. Likewise, having sex in water volition not prevent pregnancy.

And then, there you have it. Probably more than than you ever idea you'd know nigh the lifespan of sperm. Still take questions? Experience complimentary to drib us a comment. We practise our best to assist.
