Male factor infertility is common. There is insufficient knowledge in the general population of how to optimise fertility in men, and preconception counselling often focuses on female factors. This article provides advice on preconception care for men and discusses strategies that may be implemented to optimise male fertility based on the existing evidence base.
About one in six couples experience infertility and 50% of cases are due to male factors, either as a sole cause or as a contributing factor.1 Although there is increasing awareness about optimisation of general and reproductive health before pregnancy, preconception counselling primarily targets women. Male partners often receive less attention and less is known about preconception care for men.2
