What is natural birth control?
natural contraception, also called the rhythm method, implies that one should not have sexual relations during the ovulatory menstrual cycle of women (this is the time in which the ovary eliminates the egg and the woman is fertile). It is then easier to get pregnant. The natural contraception method is the most accepted by all religions.
How is natural contraception plan?
diagnosis is required when the ovary is ovulating. This is when you remove the egg, this happens once a month. A woman can get pregnant a few days before or after ovulation. Sperm can live 5 days and 24 hours the egg. This indicates that even if you have intercourse a day that is not ovulating, you can still get pregnant, 5 days after ovulation and sperm are still alive. Or if you have ovulated and have sex the day after, can you get pregnant, because that egg is alive and can be fertilized. So as not to have sex a few days before and after ovulation.
ovulation should be detected by one or by several methods. The methods of diagnosing ovulation can be: a) observation of basal body temperature (taking the temperature first thing in the morning without moving in bed), b) changes in cervical mucus (it becomes transparent and ropy) and c) peak detection of LH (the hormone that starts ovulation).
There are even handheld computers that help detect ovulation. It must keep track of menstrual periods. When it has detected that you are ovulating, you should not have intercourse during the fertile time.
How effective is natural family planning method?
If a woman uses the method of natural family planning, every time you have sex and follow the instructions provided (always detect ovulation and abstaining from sex during that period) is 91-98 % effective. That means that if 100 women use natural family planning method all the time and do it right, 2 of 100 women will become pregnant within 1 year.
The perfect use hardly ever happens, and there's the rub. Should be diagnosed monthly ovulation, because the periods and the date of ovulation vary from one cycle to another. This is truly difficult. If a woman uses natural method, but it takes into account all the while maintaining sexual relations is 76% effective. This means that if 100 women use natural family planning method, 24 women become pregnant each year.
High rates of errors occur when using the method of natural family planning cycles are irregular. These are much more common in adolescents. Even a disease can change the basal body temperature and vaginal infection alter the characteristics of cervical mucus. The natural family planning method does not protect against sexually transmitted diseases. If this theme is concerned it does not maintain a stable and monogamous relationship, you should use a complementary method to cover you from sexually transmitted diseases (condom).
