Youve asked yourself this question not once and never got irrefragable answer? The lack of awareness makes you embarrassed in the consulting room? Then youre in proper place. The variety of birth control methods with short description and the rate of effectiveness youll find below.
For the lowest rung of the ladder of efficacy are compete such barrier birth control methods as spermicides, diaphragms and female condoms. The failure rate for them is from 4 to 36 %. What makes people choose them?
Spermicides (widely presented as foams, creams, vaginal tablets, jellies and dissolvable films) break sperm cell membrane and in this way inactivate it. The time of action is from 20 minutes to 1 hour. Spermicides give some protection from sexually transmitted diseases.
Vaginal diaphragms and caps are more tiring in caring and checking in addition to probable uncomfortable feelings. As other barrier methods vaginal devices do not interfere with hormone levels. A distinguishing feature is the possibility to have sex during period.
Had you know that such a widely used method of contraception as male condom fails in 2-12 %? Hence it takes up the second grade. The next place in this layout is destined for emergency contraception (the rate of failure reaches 2%). The morning after pill is effective within 72 hours of unprotected sexual intercourse. It gives the body a short, high burst of synthetic hormones; and unpleasant side effects (nausea, vomiting or irregular bleeding).
97.5-99.6% of efficacy provides intra-uterine device. A small plastic or copper T-shaped stick with a string attached to the end, which placed inside the uterus is more apt for women that already have enough children and dont much care about their fertility. Nobody knows for sure how this simple device prevents pregnancy (there is a suggestion that it changes the lining of the uterus), but its comparative cheapness and easy use (one device works from 2 to 10 years) make it fairly popular.
There is no birth control method which makes no harm to your body at all and at the same time is highly efficient. If you also think so be sure that youre wrong.

Its numerous benefits include reducing menstrual bleeding, prevention iron deficiency anemia and pregnancy outside the womb, reduction of a risk of cancers and speeding up the diagnosis of breast cancers. Enduring use detected also a lot of its side effects, such as risk of heart attacks, blood clots in the deep leg veins, weight gain or emotional changes. Synthetic hormones prevent ovulation with efficacy 90-99.9%.
So called injectables use an uncommon for contraceptives way of delivery of hormones into the bloodstream. One injection in 13 weeks provides 99.4-99.9% of efficiency and frees from necessity to swallow pills every day.
On the top of this survey youll find sterilization. Female sterilization has a failure rate 0.1-0.4%, male sterilization less than 0.1%
