Jewish law considers children a blessing. So a man may not abstain from procreation or get sterilized until he has fathered a child. Conservative and Reform Jews feel that the benefits of birth control (female health, family stability, or disease prevention) uphold the commandment to "choose life" more strongly than if they violate the commandment to "be fruitful and multiply."
The Jewish laws of niddah (family purity) do not allow a woman to have sex during her period. If an Orthodox Jewish woman wants to use contraception, she may choose a method that decreases the chances for additional bleeding. Judaism also suggests that brides use the combination pill. Due to niddah, Jewish brides can try to regulate their periods before their wedding to lower the chances of having it on their wedding day. That is because after the marriage ceremony, Jewish newlyweds are supposed to retire to a private room for time alone, known as Yichud. Yichud allows for the consummation of the marriage and is a requirement under Orthodox Jewish law.
