already long gone are the days when the birth rate was controlled solely by means of abortion.Today, the question of whether protected or not, everyone decides for themselves.Of course, this requires a serious and responsible attitude, and if the means of contraception has been chosen correctly, the consequences may be the most "deplorable."
should be noted that the protection should be seen not only as a form of protection from the conception of the child, but also as a kind of saving the mother's health and the ability to give birth to a strong baby when you wish.
However, it should be noted that no method of contraception can not give absolute guarantees of pregnancy.Often, in order to achieve maximum effect, experts recommend using a combination of several birth control pills.At the same time before you make a choice in favor of one or another method of contraception, be sure to consult with your doctor.
Classic version of contraception - the so-called barrier methods.In the first half of the last century, various types have been almost the only escape from an unwanted pregnancy.
However, science gradually evolved, and on drugstore shelves, over time, other forms of contraception, which have reduced the popularity rating of barrier methods of contraception.Curious fact that when use of modern means of contraception, it somehow gave more complications than the use of standard condoms.
mechanism of action of barrier contraceptive method is based on the fact that contraception prevents the penetration of sperm in the cervical mucus.This is the condom, contraceptive sponge, cervical caps, and vaginal orifice.
advantage of these products is that they are used locally and not provoke the emergence of any changes.Therefore, contraception, referring to barrier methods, has far fewer contraindications than other variations of protection against unwanted pregnancy.It also effectively protects against sexually transmitted diseases.
However, barrier methods has its drawbacks.Compared with the intrauterine and oral contraceptives, it is less effective.Some products in women cause an allergic reaction to latex or rubber.
However, reliable means of contraception are made also with different chemical compositions.How do they work?In the vagina by a jelly, aerosol foam or cream spermicides are placed, which subsequently destroy the sperm during its movement to the uterus.Taking into account the fact that the sperm is able to "reach the target" and a half minutes from the end of sexual intercourse, it is safe to say that chemicals in terms of quality and speed to protect against unwanted pregnancy inferior to other contraceptive methods.
Of course, an effective means of contraception are not limited to the above two.There are biological, calendar, temperature, cervical prevention methods.
