Samuel,

You should seek some medical advice from a doctor who understands Catholic Moral teaching and find out if there is any medical issue preventing either one of you from conceiving. (Other sources.) You can also try Natural Family Planning techniques to determine when she is ovulating and the best times to try and conceive. Do a little research on the internet.

You should also pray — with your wife — together, for your mutual fertility — and God's will for both of you. God is the author of life and this is a 3-way deal. It is not up to either one of you, but Him.

Remind your wife that she married a husband, not simply a sperm donor. There are no guarantees about fertility in a marriage, and certainly circumstances vary from time to time making conception harder to come by. Many couples have to wait years before it happens.

My wife and I could not conceive because my wife had a medical issue, so we adopted. Sometimes God works in different ways. I know a couple who couldn't conceive, adopted, and then got pregnant a year later! You just can't tell what will happen.

Just pray and do some homework.

You may need some marriage counseling if she doesn't seem to get it.

Peace,

Bob
