Sleeping with sperm in you is a common concern for people who are trying to conceive or are worried about the possibility of pregnancy. Sperm can live inside the vagina for up to 7 days, and there is no scientifically proven way to remove it once it has entered the cervix. While there are anecdotal suggestions, such as urinating, showering, bathing, or using vinegar, these methods are not supported by research and may cause irritation. To avoid pregnancy, it is recommended to use birth control methods such as condoms or hormonal contraception. Additionally, lying still for 10 to 15 minutes after ejaculation can increase the chances of conception by allowing gravity to move the semen toward the uterus.

What You'll Learn
There are no proven ways to remove sperm from the body
There are no scientifically proven ways to remove sperm from the body. Urinating, showering, bathing, or using vinegar are purely anecdotal methods of removing semen from the vagina after sex. Research does not support their effectiveness, and some of these approaches may cause irritation. Urine comes out of a small hole called the urethra, so urinating will not remove sperm from the vagina. Showering or douching is also ineffective, as the water will be unable to reach the semen in the uterus.
Some people believe that inserting vinegar into the vagina may kill sperm due to its high level of acidity, but there is no scientific evidence to prove this, and it may lead to irritation. There is little evidence to suggest an effective way of removing semen from the vagina. If someone prefers to clean their vagina and vulva after sex, the safest way to do so is with unscented soap and warm water.
While there may be no medical reason to shower after sex, it is still good to have a post-sex routine. The vagina is capable of cleaning itself after sex, even if there is sperm inside. However, trying to take matters into your own hands can do more harm than good. Products that claim to 'clean' the vagina or vulva, especially douches, should be avoided.
If you are trying to prevent pregnancy, emergency contraception is the only effective method to use after sperm has entered the vagina during unprotected sex. It is important to contact a doctor as soon as possible, as they may prescribe emergency contraception such as Plan B, which can be taken up to 72 hours after sex.

Some sex positions may be more effective for conception
Sperm is the male reproductive cell that, when combined with a female's egg, can lead to pregnancy. Once ejaculated into the vagina, sperm can reach the cervix within 15 minutes to a few hours, and it can live inside the vagina for up to seven days.
While there is no specific sex position proven to improve the odds of getting pregnant, certain positions may be more effective for conception. It is important to note that pregnancy is possible in almost any position as long as sperm enters the vagina. This includes positions considered "gravity-defying," such as standing, sitting on the lap, or the cowgirl and reverse cowgirl positions.
Some sources suggest that lying down after sex may facilitate sperm mobility to the uterus, but evidence has proven this behavior to be unnecessary. Instead, understanding your menstrual cycle and timing intercourse around your fertile window" is more crucial for conception. This window is the five days before and the day of ovulation, when the ovary releases a mature egg that travels down the fallopian tube toward the uterus. Having live sperm in the fallopian tubes during this time increases the chances of fertilization.
Additionally, certain lubricants like Astroglide and K-Y Brand Jelly can reduce sperm motility and viability, potentially lowering the likelihood of conception. If you are trying to conceive, consider using hydroxyethylcellulose-based lubricants, mineral oil, or canola oil, as these are similar in texture to natural vaginal mucus and do not slow down sperm.

Water-based lubricants may inhibit sperm movement
Sleeping with sperm in you means there is a chance you could become pregnant. Once semen has entered the cervix, there is no scientifically proven way to remove it. Urinating, showering, bathing, or using vinegar are purely anecdotal methods of removing semen from the vagina after sex, and research does not support their effectiveness.
If you are trying to conceive, it is important to note that many vaginal lubricants can impair sperm movement, making it difficult for sperm to reach an egg. This is because lubricants can reduce the ability of sperm to move spontaneously and actively toward the egg. While it is up for debate whether lubricants decrease pregnancy rates, it is generally recommended to avoid most lubricants when trying to conceive. Lubricants can limit the ability of sperm to be motile, or swim, which is essential for reaching the egg and fertilizing it.
However, not all lubricants are harmful to sperm. Fertility-friendly lubricants are tested to ensure they are safe for conception. These lubricants are hydroxyethylcellulose-based and do not decrease sperm motility. They are also similar in consistency and viscosity to natural vaginal mucus, making them a great match for sperm. To be sold, these lubricants must be evaluated and cleared by the Food and Drug Administration (FDA).

Sperm count is slightly higher in the morning
Sperm is the male reproductive cell that combines with a female egg, leading to pregnancy. While there are several anecdotal methods to remove semen from the vagina, such as urination, showering, bathing, or using vinegar, there is no scientifically proven way to remove it once it has entered the cervix.
Recent studies have shown that sperm count is slightly higher in the morning, specifically before 7:30 a.m. During sleep, the male body regenerates sperm lost during the day, resulting in higher sperm concentrations upon waking. A study of 12,245 semen samples from over 7,000 men found that sperm concentration, count, size, and shape were highest around 7:30 a.m., with no changes in progressive motility.
However, it is important to note that the time of day you have sex likely has a minimal impact on your chances of conceiving. For example, a difference of one million in sperm count between morning and evening represents only a 1% change. Rather than focusing on the time of day, maintaining a healthy lifestyle, a balanced diet, and a healthy weight will help keep sperm in top condition. Additionally, fertility doctors emphasize the importance of timing sex with ovulation, which plays a pivotal role in conception.
Furthermore, while sperm count may be higher in the morning, total motile sperm count, which is significant in achieving successful fertilization, tends to be higher in semen collected in the evening. Thus, for those seeking artificial insemination, semen collection typically occurs in the early morning, while successful intrauterine insemination may be easier with semen collected in the evening.

Sperm may swim more effectively with gravity
Sperm is the male reproductive cell that combines with a female's egg, potentially leading to pregnancy. Once semen has entered the cervix, there is no scientifically proven way to remove it. Urinating, showering, bathing, or using vinegar are purely anecdotal methods of removing semen from the vagina after sex, and research does not support their effectiveness.
Gravity has been observed to cause immobilized sperm heads to turn downward, after which the oriented spermatozoa continue to move down by their own tail movements, causing an accumulation of motile spermatozoa at the bottom. This may explain why, in some studies, the swim-down procedure was superior to the swim-up procedure during sperm separation by self-migration. Under the influence of natural gravity force, most immobilized spermatozoa turned their heads down in about 5 minutes and then sank slowly at an average speed of 0.2 mu/s. The number of motile spermatozoa that swam down was 5-6 times more than those swimming up.
The female reproductive tract can be likened to an obstacle course designed to weed out weak sperm. Research by Baker and Bellis has examined how much "flowback" sperm is lost after coitus. While there is no mention of whether tilting the pelvis can make things easier for sperm, it is worth noting that sperm can survive for up to five days while waiting for an egg. Therefore, assisting them with gravity for 15-20 minutes post-coitus may not make a significant difference.
However, some sources suggest that working with gravity could potentially help. For example, a WebMD article quotes doctors who claim that elevating the pelvis after sex can increase the chances of conception. Additionally, a study by Saleh from 2000 found that bed rest made a significant difference in pregnancy rates for women undergoing intrauterine insemination (IUI). In this study, 29% of those who rested in bed for 10 minutes after the procedure became pregnant, compared to only 10% of those who did not rest.
While the role of gravity in sperm motility and conception is still being explored, it is important to note that uterine contractions also play a significant role in drawing sperm toward their target, and these contractions are stronger right before ovulation.

Frequently asked questions
Lying still on your back for 10 to 15 minutes after ejaculation is recommended by some fertility experts to improve the odds of conception. This is because it allows gravity to move semen towards the uterus. However, there is no scientific evidence that lying down after sex increases pregnancy odds.
There is no scientifically proven way to remove sperm from the body once it has entered the cervix. Urinating, showering, bathing, or using vinegar are all anecdotal methods that are not supported by research and may cause irritation.
There is no way to tell how much sperm has entered the uterus or reached the fallopian tubes. If conception occurs, you may experience signs of pregnancy within one to five weeks, which you can confirm with a pregnancy test.
