First what does God tell man:
1:27. And God created man to his own image: to the image of God he created him: male and female he created them.
1:28. And God blessed them, saying: Increase and multiply, and fill the earth, and subdue it, and rule over the fishes of the sea, and the fowls of the air, and all living creatures that move upon the earth.

How does He deal with those who disobey?
38:9. He knowing that the children should not be his, when he went in to his brother's wife, he spilled his seed upon the ground, lest children should be born in his brother's name.
38:10. And therefore the Lord slew him, because he did a detestable thing:

CCC-2370-calls it an "intrinsically evil".
Pope Paul VI predicted in his encyclical "Humanae Vitae" that with the use of contraceptions it would lead to greater evil's such as abortions.
