Contraceptive methods, male and female, which separate physically contact of sperm with the eggs.

Nowadays Both men and women can enjoy an active sex life, we partner or not, avoiding pregnancy effective way. For this we have many contraceptive system, which can be used by both men and for women. Generally fall into two types: hormonal contraceptives or barrier. Barrier contraceptives are those that prevent, through a physical medium, the contact of male sperm with female ovum.

Male and female condoms

Besides preventing pregnancy, this method is the most effective way to avoid contracting sexually transmitted diseases (STDs), making it the most common for casual sex. Have an efficiency of 99%.
The best known are the male condoms Composed of a thin latex bag to be placed impermeable covering the penis, which prevents direct contact between this and the woman’s uterus. Usually on the inside have spermicide, and even prolong erection retardant. We can find different sizes, colors and even flavors.
At present, we can also acquire female condoms. Consisting of a soft and thin pouch of polyurethane with two flexible rings at each end. In the inner ring, closed, serves to position and fix the female condom in the uterus and the outside cover of the external genitalia.

Diaphragm and contraceptive vaginal sponge

The diaphragm, With an efficiency of 94%, blocks sperm so it can not reach the egg, preventing pregnancy, but as no direct contact between the sperm inside the woman is not effective against STDs. This is a glass of flexible rubber or latex, which is impregnated with spermicide and placed in the neck of the uterus, or cervix, just before sexual intercourse and the woman has to keep in place between 6 and 8 hours after intercourse. The gynecologist has to tell which one is right for every woman, because they are of different sizes.

Another similar method is the vaginal contraceptive sponge, a soft synthetic sponge, which has also become impregnated with spermicide into the vagina and keep the hours after intercourse. It can be purchased without a prescription at any pharmacy but has a slightly lower efficiency than the diaphragm (82%). It is also not effective against STDs.

Vaginal spermicides

The spermicides may be included here, as through a chemical process to disable sperm in semen. On sale at any drug store or sex shop, are ineffective as a contraceptive used only with an accuracy of 79%, but are a good supplement to boost the reliability of other methods. They appear as foams, gels, creams or suppositories to be applied in the vagina before intercourse.

Male and female sterilization

As a method of contraception for those who do not want children there sterilization. This is done by an operation and is irreversible, though not always 100% effective, is very reliable. In the case of the wife’s name tubal ligation and the man Vasectomy.

The “Reverse” and Ogino-Knauss method

Not considered, properly, birth control though many use them as such. We include them here because, with them, it is intended that the sperm does not come into contact with the egg. The “Reverse”Or coitus interruptus, Consists of removing the penis from the vagina before ejaculation, is not effective because before ejaculation can produce output of some sperm fertilize the egg. The Ogino-Knauss method limiting sex to the female menstrual cycle during which the risk of conception is lower. It involves sexual abstinence for at least 10 of every 28 days and is not effective, because the woman may have spontaneous ovulation during the cycle.
