The Jewish view on birth control currently varies between the Orthodox, Conservative, and Reform branches of Judaism. Among Orthodox Judaism, use of birth control has been considered only acceptable for use in certain circumstances, for example, when the couple already has two children or if they are both in school. However, it is more complex than that. The biblical law of being "fruitful" and "multiplying" is viewed as one that applies only to men, and women have no commandment to have children. This is the reason why women are the ones to choose a form of contraception that they wish to use (i.e. spermicide, oral contraception, intrauterine device, etc.), while males don't. Generally speaking, when Orthodox Jewish couples contemplate the use of contraceptives, they generally consult a rabbi who evaluates the need for the intervention and which method is preferable from a "halachic" point of view. Including the previously mentioned reasons (already having children, student status, etc.) there are many other reasons for a rabbi to grant a couple permission to use contraception. In many modern Orthodox communities, it is recommended for young newlywed couples to wait a year before having a child so as to strengthen their marital foundation and their relationship before bringing children into the home. This is because children generally require a strong parental unit, and bring challenges and difficult decisions which can be a heavier burden on the marriage itself if the parents are not functioning together well. Since marriage is a sacred relationship of the highest importance in Judaism, couples are always counseled to behave and live in a manner that constantly works to uphold a happy and loving home; this may include planning to slightly delay having children when the couple has had a speedy dating and marriage timeline (as is common in Orthodoxy when many couples abstain from premarital sex).
