Hormonal Methods
There are a lot of various methods for hormonal contraception.
Basically combinations of an estrogen and progestins (synthetic forms of a progesterone) are used. They include the combined oral contraceptive pill ("The Pill"), the Patch, vaginal ring, and Lunelle (the monthly injection at present inaccessible to purchase).
The structure of other methods includes only progesterone. They include a progesterone only a pill (POP, mini-pill), Depo Provera (the injection each three months), and introduces such as Norplant or Implanon. Progesterone is the only pill needed to be accepted precisely at a time every day, as against combined pills. Various methods only for progesterone can cause an irregular bleeding within several months.
Intrauterine Methods
They are devices which are placed in the uterus. They are usually formed similarly to "T" - arms T hold the device in a place in the uterus.
Intrauterine the spiral is considered excellent contraceptive means if it approaches you. It is made of copper and copper is the contraceptive factor as changes a microhabitat in a uterus, creates barrier to movement sperm and egg and by that prevents both conception, and introduction egg in a uterus.
IntraUterine Systems ("IUS") release progesterone or progestin.
Periodic Abstinence
In a basis of this method there is a finding-out of an exact method of ovulation (that is to time of an output mature egg when the probability to become pregnant is maximal) by studying signals of own organism. It is necessary to use a calendar, to take temperature and to investigate vaginal allocation (Billings ovulation method, Creighton Model).
Thus "dangerous days" in which it is just necessary to do without affinity are defined. Having united all three methods, it is possible to reach a high degree of safety. This method is natural, does not demand chemical preparations and mechanical means.
This method is based that egg and spermatozoon will behave how it is necessary, and does not take into account that the organism can react differently to infections, viruses and other diseases, and they, certainly, can be reflected in rise in temperature and changes allocation, and it, in turn, will lead to wrong definition of day ovulation.
Lactational
The majority of women during feeding the child by a breast have the period of barreness. Lactational Method Amenorrhea, or LAM, give main principles for determining length of the period of the woman’s breastfeeding infertility.
Constant Contraception
The method of sterilization in a life is known as « bandaging of tubes». Fallopian tubes tie or drawn to not allow sperm to pass on them, and egg do not allow to go down in a uterus. An egg, as before, ripens, but simply resolves in an organism. Operation is usually done under the general narcosis, a method of a laparoscopy. Restoration of genital functions not always happens possible and successful, each case is special. The percent of successful "return" operations makes from 30 up to 60.
Vasectomy for man is a simple 20-minute operation which does not allow sperm to get in the seed channel. Sperm is still developed, on is absorbed by an organism. It is carried out under local or general anesthesia, the surgeon does a cut in scrotum and draws seed rope. It is required not less than sixteen ejaculation before the seed channel will completely be exempted from sperm. But before to be solved on it, it is necessary to think well. Even if operation on restoration will pass successfully, there are no guarantees, that the man then can become the father.
