In the past the use of family planning birth control methods including artificial contraception was explicitly condemned by LDS church leaders.
In contrast with some orthodox Christian movements, sexuality in Mormon theology is neither a product of original sin nor a "necessary evil".
However, in teaching children about sexual morals and birth control, Mormons parents have ranked among the lowest in comfort discussing these topics with their children among US parents of all religious affiliations.
In discussing another method of family planning the church "strongly discourages" surgical sterilization like vasectomies and tubal ligation and only allows it for serious medical conditions after discussing it with a bishop.
Sexuality has a prominent role within the theology of Mormonism.
The Church of Jesus Christ of Latter-day Saints (LDS Church) teaches that gender is defined in the premortal existence, and that part of the purpose of mortal life is for men and women to be sealed together, forming bonds that allow them to progress eternally together in the afterlife.
