People of many nations and faiths have documented their search for safe, reliable contraception that protects women from unintended pregnancy and protects everyone from STD's since 2000 years before the birth of Christ.
The fact that we as a species finally figured out (mostly) safe and very effective ways to prevent the transmission of disease, save women from having too many children too close together, save women from dying of dangerous pregnancies, and help people actually manage their fertility is an amazing feat. The solutions we have come up with so far have their risks and imperfections, and I hope we continue to work in creating safer options that give us even finer control, but we all benefit from individuals having control of their own fertility and being able to make their own choice-- a choice borne out of their particular health issues, family history, personal situation, and desire for children.
For me is is a religious issue in that I thank God for giving us the brains and scientific inclination to figure ourselves out and to choose how we want to live. God gave us free will and we chose the world and all its puzzles and mess. Choice and living into the consequences of choice is God's gift to us-- and God seems to have a 'no take backs' policy. Choice is not limited to issues of fertility, but fertility/sexuality/gender expression (and which members of society control expression of those aspects of personhood) seem to me to be the most passionate and personal battlegrounds for choice.
