Sperm generally dies within a few milliseconds of leaving the human body, but it can survive outside the body for up to 20 minutes. When exposed to air, sperm dries out and dies within moments of exposure to oxygen. It is highly unlikely to get pregnant without penetration, and penetration and ejaculation inside or near the vagina are required for pregnancy. While it is possible for sperm to be transferred to the vagina via the fingers, this is very unlikely to cause pregnancy. Washing the hands with soap, shampoo, or water is enough to remove any sperm remains.

What You'll Learn
Sperm exposed to air
When sperm is exposed to air, it dries out and dies within moments of exposure to oxygen. Sperm needs a warm, moist environment to survive. Therefore, when it is outside the human body, it cannot survive for long.
Although oxygen does not kill sperm, they can only move until they dry out. Once they are dry, they die. This is why it is highly unlikely to get pregnant from fingering, as the sperm will not be able to survive outside the body long enough to reach the uterus.
Additionally, sperm that has been ejaculated into a woman can live inside the uterus for 3 to 5 days. This is why it is possible to get pregnant if you have unprotected sex while menstruating. If you ovulate shortly after your period, the sperm may still be alive and can fertilize the egg.

Sperm survival outside the body
Sperm generally cannot survive outside the human body for long. Once outside, they die within a few milliseconds due to exposure to oxygen, which causes them to dry out and become non-functional. This means that sperm exposed to the air or present on the fingers or fingernails will quickly die and are highly unlikely to cause pregnancy without penetration.
However, there is a possibility that fresh or viable sperm on fingers or under fingernails could cause pregnancy if inserted into the vagina. While sperm cannot seek refuge under fingernails, they are very small and may go unnoticed. Therefore, it is generally recommended to wash hands thoroughly with soap, shampoo, or water to remove any sperm remains and prevent potential risks.
The survival of sperm outside the body also depends on the environment they are released into. For example, sperm can live outside the body for about 20 minutes, and within two hours, any semen under the fingernails would have dried. Additionally, nail length and the presence of nail polish could potentially impact the survival of sperm under nails, although there is limited information on this.
In summary, while sperm generally die very quickly outside the body, proper hygiene practices, such as handwashing, are important to ensure the removal of any sperm remains and prevent any potential risks associated with sperm transfer.

Sperm survival under nails
However, it is theoretically possible for sperm to survive under nails for a short period. Sperm can only live outside the human body for about 20 minutes, and they dry out and die within moments of exposure to oxygen. Therefore, if someone has fresh sperm under their nails and inserts their fingers into their vagina, there is a slight possibility of pregnancy.
It is important to note that this scenario is highly unlikely, and there is no risk of pregnancy in most cases. Sperm cannot swim to reach inside the uterus, and penetration and ejaculation within or near the vagina are necessary for pregnancy.
To prevent any anxiety or potential risks, it is recommended to wash hands thoroughly with soap, shampoo, or water, as these are enough to remove any sperm remains. Sanitising hands is also a good practice.

Pregnancy risk from fingering
The risk of pregnancy from fingering is generally considered to be very low. Sperm must come into contact with the vagina for pregnancy to occur, and fingering typically does not introduce sperm into the vagina. However, pregnancy can potentially occur if a partner ejaculates near the vagina and then introduces semen into the vaginal canal with their fingers.
Sperm can survive outside the human body for only a few milliseconds before dying. When semen is present on the fingers or fingernails, exposure to air can quickly kill the sperm. Therefore, the risk of pregnancy from fingering is minimal, and it is practically impossible to get pregnant without penetration.
However, it is important to note that the risk is not completely non-existent. To prevent pregnancy and sexually transmitted infections (STIs), it is recommended to keep ejaculate and pre-ejaculate fluids away from the vagina and surrounding areas, including fingers. Washing hands before and after sexual activity is essential.
The use of reliable birth control methods, such as the birth control pill, can also help prevent pregnancy. Additionally, finger condoms or gloves made of latex or nitrile can be used during fingering to reduce the risk of both pregnancy and STIs.
If there is concern about potential pregnancy after fingering, emergency contraception may be considered. Consulting a doctor or healthcare professional is advisable in such situations to discuss options and receive guidance on the best course of action.

Cleaning sperm from under nails
Sperm generally dies within a few milliseconds of being outside the human body, as exposure to oxygen causes it to dry out and die. However, if you are concerned about cleaning sperm from under your nails, there are a few simple steps you can take.
First, it is important to wash your hands thoroughly with soap or shampoo, as this will help to remove any sperm remains. You can scrub your hands with soap or shampoo for 10-12 seconds, or even up to 15 seconds if you prefer, and then rinse your hands with water for an equal amount of time. Either cold or warm water will be adequate, and the temperature of the water does not seem to matter.
If you are particularly concerned about the cleanliness of your nails, you may also want to consider using nail glue. Some people report that their nail technicians use nail glue under their nails to create a barrier and protect the nail.
It is important to note that the risk of pregnancy from sperm under your nails is extremely low, as penetration and ejaculation inside or near the vagina are necessary for pregnancy to occur.
