1. Calendar method (70%)
Perhaps the most ancient way (besides abstinence) and one of the most dangerous. It can be useful for those who have a clear cycle, with understandable timing of ovulation. But there are few such women. In addition, even the most stable organism can fail.
2. Female condoms (79-95%)
Relatively new and not very popular way. The difficulty is that you need to be able to use this subject, and not many succeed the first time.
3. Male condoms (85-95%)
In general, the reliability of this method exceeds 98%, but the statistics are spoiled by those who put it on too late or incorrectly.
4. Injections (99+%)
One of the most reliable ways. Does not depend on other medications, works to prevent ovulation. The main thing is not to skip the next injection in 2-3 months.
5. Combined oral contraceptives (91-99%)
They are pills. The main mistakes are an insufficient level of hormones for a particular organism and forgetfulness. Strong antibiotics may also have an effect.
6. Pills with progesterone, mini-pill (91-99%)
In this case, the reception time is even more important. Mini-pills are prescribed for breastfeeding, a family history of breast cancer or intolerance to regular pills.
7. Spirals (95-99%)
Hormonal coils release small doses of hormones into the body to prevent ovulation. Non-hormonal ones affect the tissues lining the bottom of the uterus so that the embryo cannot attach. In exceptional cases, they can be used as emergency contraception 3-4 days after unsafe sex.
8. Vaginal ring (92-99%)
Inserted inside the vagina, it gives out small doses of hormones. Needs to be changed once a month. It does not depend on taking other medications – hormones enter the reproductive system immediately.
9. Implant (99+%)
Statistics show that only one in a thousand women becomes pregnant within three years of implantation.
10. Interrupted act (statistics unknown)
This method cannot be recommended in any case: spermatozoa can be released during the entire intercourse.
11. Emergency contraception (95%)
Unpleasant for the body way. On the first day, the effectiveness is 95%, when taken on the third day – 89%.
