If he ejaculates between million sperm it's fairly unlikely the woman will not get pregnant. These are really rough guidelines with some exceptions. This truly makes no sense. Why do we need millions of sperm when ultimately only one sperm cell will fertilize one egg to make one embryo?
When ejaculation occurs in the vagina, the sperm is exposed to acidic vaginal fluid pH about 5. This acidic fluid will kill some sperm even as the more basic pH of the semen tries to neutralize the vaginal acid. Many sperm will quickly leave the vagina and it's acidic fluid behind, entering the cervix within minutes of ejaculation. In the cervix sperm reach another challenge. The cervical mucous, particular at the borders, is compact with a microarchitecture that is hard for abnormal sperm, or sperm that cannot swim properly, to penetrate.
Yet another challenge in the cervix is the female's immune response to sperm. White blood cells migrate to the cervix to attack foreign cells usually bacteria coming up from the vagina, but also some sperm cells. The sperm that can get through the cervix and avoid attack by white blood cells, need to find the proper path into the uterus, which isn't easy as they need to travel in the grooves of the cervix. A study of 99 men from fertility clinics in Boston concluded that excessive soy intake might decrease sperm concentration.
Honestly, these are probably the scariest on the list because they are not foods, but they still end up in what we eat. Obviously, pesticides end up on vegetables and fruits. They also end up in meat and fish due to tainted water supplies. It slowly leeches into the foods we eat. Both BPA and chemicals within pesticides act as xenoestrogens—chemicals that mimic estrogen.
Just like the phytoestrogens in soy, xenoestrogens can wreak havoc on sperm concentration. On a side note, some of the same chemicals in pesticides can come from non-stick cookware. Some of this could be due to sex steroids given to cows. One small study associated higher amounts of fish consumption with better sperm motility. Other studies were inconclusive. The benefits associated with fish for sperm health are likely due to their high concentration of omega-3 fatty acids, but the role of fish in sperm health is unclear overall.
A study of men who had sperm analyzed at a fertility clinic showed that men who ate higher amounts of fruits and veggies, particularly green leafy vegetables and beans legumes , had higher sperm concentrations and better sperm motility compared to men who ate less of these foods. This is not surprising since plant-based whole foods are high in anti-oxidants such as co-enzyme Q10, vitamin C, and lycopene.
These micronutrients have been linked to higher sperm concentrations. Several studies have shown that co-enzyme q supplements may have a positive impact on sperm health , but ultimately we need more studies to make definitive recommendations. In , in a small study, researchers assigned men ages 21 to 35 to eat or not eat approximately 18 walnuts daily for 12 weeks. The researchers analyzed sperm parameters before and after the study period. They found significant improvements in sperm vitality only in the nut group.

Don't make the mistake of letting a diet kill sperm. Call Us At Is declining sperm quality really a problem? Sperm can live inside the vagina for up to 7 days. Once sperm enters the uterus, there is no scientifically proven way of removing it. Between a few minutes and several hours after intercourse, some fluid may come out of the vagina.
Although some of this may contain sperm, it will mainly consist of a mixture of proteins and vitamins from the ejaculation. Although anecdotal evidence suggests that there are ways to remove semen from the vagina, there is no scientific proof to support these claims. Some of the proposed techniques include:. There is little evidence to suggest that there is any effective way of removing semen from the vagina.
If someone is attempting to remove semen from their vagina to prevent pregnancy, they should contact a doctor. The doctor may be able to prescribe emergency contraception, such as Plan B. Plan B, also called the morning after pill, works by stopping the ovary from releasing an egg. It is possible to take Plan B up to 5 days after sex, but taking it earlier is more effective.
For those who do not wish to get pregnant, there are several ways to prevent pregnancy. People typically use hormonal and nonhormonal birth control methods, but some individuals may also consider natural or surgical methods to prevent pregnancy. Learn more about these birth control options.
Anyone who wishes to take birth control should discuss the options with a doctor to determine which option may be best for them. Some birth control options are more effective than others in preventing pregnancy. However, the only guaranteed way to avoid getting pregnant is abstinence.
If someone prefers to clean their vagina and vulva after sex, the safest way to do so is with unscented soap and warm water. Some people claim that urinating, showering, bathing, or using vinegar may remove semen from the vagina after sex. However, once semen has entered the cervix, there is no scientifically proven way to remove it. If someone is attempting to remove semen from the vagina to avoid becoming pregnant, they should contact their doctor.
