While many statements exist condemning contraception, there is no public statement from any apostle positively recommending its use. All Church leaders preach the same message: The use of birth control by LDS is contrary to the will of God, so the contraceptive use is not specifically encouraged. The text in the LDS General Handbook leaves it up to the married couple to choose. After careful thought and prayer, if a couple has decided that they should not have children at this time, birth control is acceptable (not just abstinence), since the Church recognizes that sexual relations have an important place in expressing and demonstrating the bond of love.
Research shows that the large family size among Mormons is not due to their reluctance to use contraception; in fact, Mormons are just as likely to use modern birth control methods as the rest of the nation. The difference may be that contraceptives are either not used until after child rearing has occurred or are used less often, so that Mormons can reach their desired larger-size family.
