Modern means are issued in the form of the letter "T". The intrauterine contraceptive contains hormones or copper, which affect the endometrium and motility of spermatozoa. These drugs are considered highly effective, as they impede full fertilization. But their use is recommended already giving birth to women. In addition, after 5 years they are recommended to be replaced. They also have contraindications: inflammatory diseases of the genital organs, pregnancy, endometriosis, etc. The introduction of intrauterine devices should be under the supervision of a doctor, after the procedure it is necessary to make ultrasound of the vagina. Intramuscular means include special gels, suppositories, and creams that suppress the process of ovulation. However, these medications do not protect against various sexually transmitted diseases.

Physiological methods
These contraceptive methods are based on the calculation ofthe most favorable days for sexual intercourse. Thanks to them, some girls calculate the days when ovulation occurs. One of these methods is the rhythm or calendar method. To correctly calculate the days you need, you need to know the length of the menstrual cycle. As a rule, ovulation occurs on the 14-15 day from the beginning of menstruation. 5 days before and after the middle of the menstrual cycle are considered the most likely for conception. Therefore, at this time it is necessary to follow additional methods of contraception (for example, condoms). To correctly calculate the days, the menstrual cycle should be regular. Its duration is usually about 30 days. The method of basal temperature measurement helps to find out if a woman has ovulation. For this, every morning, without getting out of bed, you need to measure the temperature in the rectum with a conventional thermometer. Typically, in the middle of the cycle, the temperature can rise by about 0.4 degrees. This recovery will mean the beginning of a period favorable for conception. However, this method is not very effective, since a rise in temperature can be associated with illness or other factors. Interrupted sexual intercourse is another popular way to prevent conception. It involves the extraction of the penis from the vagina before the ejaculation begins. However, this method brings psychological and sexual discomfort to partners. In addition, the probability of conception with this method of contraception is still great.

After the procedures, the return of the reproductive function is possible, but unlikely. Such surgical blocking is recommended for men and women who categorically do not want to have children, their age exceeds 35 years. There are a number of contraindications for the procedure: psychological deviations, infectious diseases, the presence of a tumor. When choosing a remedy, you should carefully consider all the possible options. In order to make the right decision, you need to consult your partner and consult with qualified specialists. After all, the health of a man, a woman and their children depends on how correct the decision will be.
