My daughter, aged 37,and her husband, aged 41, have been trying to get pregnant for over a year now with no success. My daughter thinks it is because she was on birth control for over fifteen years, but her husband recently had his sperm tested and was told that he has a high percentage of malformed sperm. Also, he smokes, I think the problem is with the sperm. Do you agree?

Summarized question: What are the chances of conception with malformed sperm?
