Does Lipitor Cause Abnormal Sperm Morphology?

My husband takes 40 mg of Lipitor daily. We have been trying to get pregnant for over year and just had a semen analysis done for my husband. The doctor said that the results came back of having 98% abnormal sperm morphology. The doctor further went on to say that his motility and sperm count were normal. My husband has only been taking Lipitor since last September could this be the cause of his abnormal sperm morphology?
