What are the alternative methods of barrier contraception?

The process of putting on a condom often disrupts the course of sexual intercourse, although most modern couples try to make this process an element of foreplay. Men can consider that a condom dulls their sensations, psychological problems with maintaining an erection may even arise. It is better for such couples to abandon the use of a condom and use other methods, such as a cervical cap or an intrauterine device.
The cervical, or uterine, diaphragm can be represented in the form of a round cap made of thin latex, stretched over a flexible ring. On the inner surface of the cap and ring there is a small layer of spermicidal paste or cream. This diaphragm is worn on the cervix after being inserted into the vagina, forming a mechanical barrier to the sperm. Spermicidal cream here plays the role of additional protection against sperm penetrated through the membrane of the diaphragm. In no case should you lubricate the diaphragm with petroleum jelly, like any ordinary cream.
You need to choose a diaphragm in the doctor’s office, in strict accordance with the size and location of the woman’s cervix, and you must definitely learn how to enter it correctly. Once a year, women are advised to check the correct selection of the diaphragm, since the parameters on which its choice depends are constantly changing. The same should be done after childbirth or when the weight changes by more than 4 kg. The diaphragm must be worn 2 hours before sexual contact, and removed no earlier than 6 hours after it ends. In no case should you wear a diaphragm for longer than 12 hours.
The cervical cap has the same principle of action as the diaphragm: it is held on the cervix like a sucker, closing it tightly. The cervical cap can be worn, however, not only for several hours, but also worn for several weeks. The reliability of the cap, as well as the diaphragm, is lower than that of the condom, and is 18% and 6% of pregnancies, respectively. With this in mind, both the diaphragm and the cap are recommended to be used in combination with spermicidal creams and gels, an additional fraction of which is inserted into the vagina.
Intrauterine contraception
 The introduction of an intrauterine device can only be done by a gynecologist. At the same time, a woman should not be pregnant or sick with any infectious disease: in the first case there is a risk of miscarriage, in the second - the risk of infection in the uterus. Quite often, the spiral is established immediately after menstruation.
The principle of the intrauterine device is based on the fact that the egg loses its ability to gain a foothold on the wall of the uterus or because of a mechanical obstacle. either due to the chemical processes induced by the helix.
Some spirals additionally contain male sex hormone - progesterone, which affects the endometrium of the uterus and also interferes with egg implantation. lvov.natashaescort.com
