Today released a large number of contraceptives for women. To understand the flow of information to the woman it is difficult, so it is best to do so, as it should be: seek assistance from a doctor and undergo a preliminary examination. Only in this case will be assigned to the most appropriate for the age and health of the woman contraceptive.
Barrier contraceptives for women and spermicide
By barrier contraceptives for women are caps and diaphragms that create a mechanical barrier to sperm on its way to the uterus. But to this obstacle was a reliable, caps and diaphragms must be chosen on the size and make it can only be a doctor. In this way, you can use contraception within six weeks after childbirth.
The diaphragm is a dome-shaped cap with elastic rim to cover the cervix. The diaphragms are made of rubber or latex, they may be of different sizes. We introduce the diaphragm just before intercourse (it can not be oiled) and can be in a woman's body for several hours. After use, the aperture is washed and dried.
The cap is made of the same material, it has a smaller size than the aperture and fits over the cervix. He stays there because of the formation of negative pressure between its rim and the cervix. Recap immediately before intercourse.
The diaphragm and cap can not be left in the vagina for a long time - it can cause complications, particularly if the woman suffers some inflammatory diseases of genitals or she has a little bleeding.
Reliability barrier methods of contraception increases when combined with contraceptives that suppress the livelihoods of sperm - the spermicide, for example, benateksom, farmateks and others. Spermicide also suppress the livelihoods of most of the agents of genital infections of bacterial, fungal, viral, and protozoa.
Of course, the barrier contraceptive and spermicide are not a reliable method of contraception.
The most modern way to prevent pregnancy - hormonal contraceptives
Hormonal contraceptives are also called oral contraceptives, that is, drugs that are taken by mouth. Current drugs of this series typically contain two types of hormones - analogues of female sex hormones estrogen and progesterone
Progesterone - norm and pathology
, Ie they are combined.
Usually hormonal contraceptives contain the synthetic analogues of natural hormones, but recently appeared preparations which contain, including natural and hormones (e.g., klayra), which produce fewer complications.
The mechanism of action of hormonal contraceptives is based on the fact that large doses of hormones inhibit the synthesis of pituitary hormones cause the mature and released from the ovary egg. If ovulation does not occur, then, of course, it does not occur and pregnancy (there is nothing to fertilize).
But that's not all. If the egg is still somehow managed to leave the ovary and into the fallopian tube, there is another obstacle to its conception: the cervical canal under the influence of hormones begins to produce very thick and sticky mucus which sperm pass can not always.
There is a third obstacle to pregnancy. If the egg is fertilized by sperm all happened, then infiltrate the lining of the uterus (the endometrium), the fertilized egg can not, as the endometrium changed its properties.

Some women do not want to use oral contraceptives or have any contraindications for their reception. Such women obstetrician-gynecologist can offer intrauterine contraceptives or an intrauterine device (IUD) - a small device made of plastic and copper that is inserted into the uterine cavity. This is a fairly reliable method of contraception, but, nevertheless, its efficiency is slightly lower than the oral contraceptives. Navy introduced a term of three to seven years.
Today also produces contraceptives that combine the advantages of hormonal contraceptives and IUDs, such as Mirena
