Choosing a method of contraception is the task that is best solved together with the doctor. The main criteria are the effectiveness of contraception (how high the risk of becoming pregnant, despite the actions taken) and the convenience of the method used. Also, one should think about the side effects of the chosen method and the complexity of rejecting the method, in case the woman wants to become pregnant. In general, the choice of a contraceptive depends on the age of the woman.
Contraceptives come in a variety of forms and forms: hormonal pills, intrauterine devices, condoms, topical preparations, injections.
Vaginal contraceptives work very simply – getting into the body, a chemical substance kills spermatozoa. Oral contraceptives do not allow the development of ovaries in the ovaries. They affect uterine mucus, make it viscous and impenetrable for spermatozoa.
Contraceptive pills inhibit or completely interfere with the attachment of the embryo to the cervix. All this does not allow the onset of pregnancy. Local preparations, such as candles, are a local and chemical method of preventing pregnancy. It is these active substances that act on the spermatozoa and make them immobile due to a violation of the integrity of the membrane.
