Why reproducttive health is against the church?

Many so-called reproductive health bills contain provisions for abortion, and contraception. The Catholic Church believes that abortion is a serious offense against the sanctity of all human life, that the infant in the womb deserves the same rights and protections that we all enjoy, and therefore opposes legislative or administrative measures that promote this procedure. And that contraception is completely opposed to God's plan for marriage, and the first command that He gave the human race: be fruitful and multiply (in Genesis).

The Catholic Church is not in favor of the Reproductive Health Bill because artificial contraceptives could possibly lead to promiscuity and the failure of implantation of a newly conceived baby if fertilization would happen to take place despite their use. These acts would be against Natural Moral Law.

On the other hand, the Catholic Church is not in favor of "natalism" at all costs, as if the "number" of children, in itself, were the unmistakable sign of authentic Christian life. Instead the Church is for responsible parenthood, meaning openness to life within marriage, and spacing of birth, only when needed for reasons of serious medical condition or grave poverty, using natural family planning methods.
