How Long Does Sperm DNA Stay in a Woman?

A social media post went viral with the claim that women absorb sperm DNA when they have sex and that it lives inside them forever. But the science behind that is shaky at best.

The reality is that sperm cells can survive for up to five days in a woman’s reproductive tract after sexual intercourse. The longevity of the DNA depends on several factors.


There are several factors that determine how long sperm DNA stays in a woman. These include her age, lifestyle choices and existing health conditions – This section is the creation of the portal’s experts sexynlive.com. In addition, a woman’s hormone levels also play a role. For example, younger women tend to retain more sperm DNA than older women.

Ejaculated sperm cells can survive inside the female reproductive tract for five days. During this time, they swim toward an egg and attempt to fertilize it. However, not all sperm cells are successful in this endeavor. The ones that do not make it to an egg are eliminated from the female body through menstruation or vaginal secretions.

It is possible for sperm to survive in the hot environment of the mouth, but it is highly unlikely that they will be able to penetrate the thick walls of the cervix and uterus. Furthermore, sperm cells that enter the female body through the mouth are likely to die due to enzymes in the saliva.

Despite this, it is possible for male cells to be found in post-coital smears of the cervicovagina. These cells are known as microchimerism, and they are most commonly caused by a previous pregnancy with a male child. However, it is not uncommon for these cells to be found in non-pregnant women as well. Nevertheless, there is no scientific evidence that these male cells are the result of sexual intercourse.

Sperm cells can survive for several days inside a woman’s reproductive tract following intercourse. During this time, they are trying to reach and fuse with the egg cells within her body. If the sperm don’t fuse with the egg, they die off or are shed through her menstrual cycle.

The quality of sperm is impacted by lifestyle factors like age, nutrition, physical activity, and psychological stress. In addition, smoking and excessive alcohol use can also diminish sperm quality. Certain medications can affect sperm DNA as well, such as anti-fungal drugs and antibiotics. Additionally, scrotal temperature can have an impact on sperm quality.

It’s possible for sperm to stay alive in a woman’s body long after ejaculation, but it’s never been confirmed that this is the case. It’s also important to note that a woman’s cervical mucus changes during ovulation, which offers a protective environment for the sperm cell.

Despite this, there’s no evidence that women retain DNA from every man they have sex with, as the claim was made on Quora. This assertion stemmed from a clickbait article on YourNewsWire that we won’t link to because it’s absurd. The post made a total of seven claims, and VERA Files broke down each of them to find out which ones are true, which are unproven, and which are flat-out false.

Sperm cells can only survive inside a woman’s reproductive tract for about five days after sexual intercourse. During this time, they will attempt to swim toward an egg and fertilize it. During this process, they will likely be exposed to the female’s hormones and bodily fluids. These factors will determine whether or not the sperm cells will be able to make it to the egg.

Each time a man ejaculates, about 100 million sperm are released. However, only a small number of these sperm will be able to survive the acidic vaginal canal and fallopian tubes. The ones that do will enter the cervical fluid and await the arrival of an egg from the ovaries.

The sperm cells that enter the cervical fluid are called microsperms and are detected using a technique known as fluorescence in situ hybridization (FISH). This test allows scientists to detect male DNA in post-coital cervicovaginal smears. This type of sex does not result in a pregnancy, but it can lead to the transmission of various sexually transmitted diseases (STIs).

It’s important for all women to practice safe sex, especially girls and young women. This includes practicing safe oral sex and always using a condom during sexual intercourse. It’s also important to have regular STI/STD testing. Getting tested can help prevent STIs from becoming diseases that cause long-term health problems, such as HIV, chlamydia and gonorrhea. Tests are easy and quick to take at NJFPL-supported health centers throughout New Jersey.

Oral Sex

There is no evidence for the claim that a man’s semen, ejaculated during unprotected sex, remains inside a woman indefinitely. A study cited by the post, however, did find that a woman’s body absorbs male DNA (deoxyribonucleic acid) from sexual partners and builds up over time — a phenomenon called microchimerism.

The same study found that a woman can detect up to five days of sperm in her cervical mucus, depending on factors like age and lifestyle choices, existing health conditions, and medications she may be taking. It also depends on where a woman is in her menstrual cycle. During ovulation, changes in hormones can change the consistency of cervical mucus. It offers a welcoming home for sperm, allowing it to live longer than if it was in normal conditions.

Oral sex is when both a man and a woman use their mouth, lips and tongue to stimulate each other’s vulva and anus. It can be done either before or after sexual intercourse, or it can replace it altogether. Some people like giving and receiving oral sex, while others don’t. It is important to know that oral sex can put you at risk of getting many sexually transmitted diseases, including STDs.

Using a condom or dental dam during oral sex can help prevent this. If you are worried about STIs, speak to your doctor.
