Natural contraceptive methods:
Now we will focus in the natural contraceptive methods, that is to say, those that do not use synthetic mechanisms not industrial to achieve the contraception. If we bear in mind the history of the contraceptive ones, we will see that many ancient cultures were using them, with major or minor success. We will always find advantages of the contraceptive natives as for minor quantity of adverse effects. Nevertheless, his effectiveness is proved to be a minor that that of other contraceptive methods. Nevertheless, the natives are quite secondhand – sometimes for lack of option, because there are the cheapest methods.
Method of the basal temperature:
This method consists of taking the anal temperature during every day of the month, and taking a record of the same one. That's why it is named also the method “of the calendar” or “of the days”. The basal temperature increases thanks to the progesterone during the ovulation. The days later to the increase of the basal temperature, will be the days of unfertility. It is a method complicated to carry out, especially if, the woman has irregular cycles, or some day forgets to take the temperature.
Method of the control of the ovulation as the method Billings:
This method consists of observing the increase or decrease of the cervical snot during the whole cycle of the woman. In general, the absence of cervical snot is accusing unfertility. As the ovulation period is approaching, the cervical snot is on the increase, and changing his consistency: of liquid, to flexible and transparent. This is not a sure method for the women who are irregular in his menstrual cycles, and for the women premenopáusicas not also. Also, it is not a method that it protects from the sexually transmitted diseases contagion.
Method mela:
This is a method that it is possible to use when the woman has just had a baby, and he is nursing it. It is considered that after the childbearing there will be a period amenorrea, of ovarian stagnation, and of unfertility.
Surgical contraceptive methods (partially irreversible):
It is quite important to clarify that these methods are not "natural" in the sense that the nature like that determines it. The contraceptive surgical ones need the hand of the man, but once the operation was done, we can say that it does not have adverse effects and that there are methods that do not imply exogenous administration of hormones not of any substance. By it there are considered to be natural contraceptive methods, although also they put a physical barrier (and in general also they can induce hormonal changes in the woman). The vasectomyIt consists of a surgery that is done to the man, where there are annulled the deferential conduits, which are After the surgery, the sperms produced by the body of the man, are re-absorbed by the same one. This method does not prevent the ejaculation. It can become reversible, but it is very difficult to do, and in general, it should be done by the same doctor who realized the vasectomy. Also, it is not a method that it protects from the sexually transmitted diseases contagion.
The tie of horns and the contraceptionThis is a method that is realized by means of a surgery to the woman. The Falopio horns unite him, so that the sperms do not meet the ovum, and so that the ovum does not come to the womb. The way of making this method reversible, is by means of an assisted fertilization. The above mentioned method can be useful in women who can run life risk with a pregnancy, or women who have had many children, and who, on having been so fertile, all the contraception methods are insecure. This method, as they will have already seen and we do not get tired of insisting, it does not protect of the sexually transmitted diseases contagion.
