There are a number of religions, and all of them have their own attitude to contraception. For Muslims all the methods that are to prevent from pregnancy are normal except of abortion and the means that kill a fertilized ovum. It goes not only about medicaments but also condoms and coitus-interruptus, but the last can be performed only if a woman agrees. Allah approved the means that favor baby birth and increase the number of Muslims, and everyone for expanding the religion and contraception should not prevent from this to go.
If the couple decided that the wife would stay not pregnant, a woman must know which means are permitted by Shariah as normal for being Islam contraception. These means should meet the following requirements: first, not to kill the embryo. For example, the loop device that is put into the uterus and also some pills that do not let the embryo to get into the walls of the womb and it dies. And second: cause no harm to the woman's health. Some hormonal contraception pills medicaments have an impact on the organism that violates the natural cycle and if the pills are being taken fro a long time it can cause adverse reaction and do harm.
Before taking up some particular type of contraception you should consult a doctor-gynecologist, and of course explain the restrictions. The best ones for the current moment are mechanical contraceptives such as caps and condoms. These ones are very like the method mentioned in Hadiths, where it is said that coitus-interruptus without ejaculation straight into the vagina.
There is also a calendar tracing method what you count out the dates when it's almost impossible to get pregnant. Among other methods we can name different gels, ointments and suppositories that prevent sperm from getting inside the uterus. The religion and contraception can "work" together to make the couple feel comfortable in the sexual life as well.
People that follow Judaism believe that God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground." Genesis 1:26-27 God blessed them and said to them, "Be fruitful and increase in number; fill the earth and subdue it." Genesis 1:28 So, He wants people to have babies and religion and contraception seems not to coincide here.
Though, contraception or natural birth control still can be applied in some cases. It can be justified when childbearing or actually being pregnant might cause harm to mother. It concerns both her mental and physical state. That radically differs from the dogmas of the Christian Church. The first also approves contraception to keep the proper level of life in the family and also the dogmas of this religion says "yes" to the ones who have sexual relationships but decide not to have offspring for the current moment.
Though it's interesting that unmarried people or people who do not have at least one child can't use contraception. As you can see, Judaism contraception allows a wide range of methods, calendar tracing and other natural birth control methods. It's rather unique, but in this religion they approve abortion. The reason for it can be one of the following points: if the mother's life is in danger because of the pregnancy, if there is a chance that a baby can be physically or mentally disabled, if the mother was raped or is very young.
A lot of unique things and traditions can be found in Judaism religion and contraception in it, and to be more precise, means of contraception accepted by it and the cases for its using, are as various as in no other world religion.
Of course an easier method may just be to use a condom.
