No, if sperm motility is better it doesn't mean that the outcome of IVF will be better. Only in severe cases of asthenozoospermia with complete loss of sperm motility it could have an adverse effect on the fertilization rate. In all other cases, the origin and the quality of sperm doesn't matter in terms of the IVF result. Women's age, on the contrary, has a major effect on pregnancy + live birth rates and sperm motility doesn't add any difference.
