The father’s nutrition and lifestyle can influence pregnancy outcomes in a number of ways. In the pre-conception period, several modifiable factors in paternal behaviour and nutrition can influence sperm count and quality, and consequently affect fertility. For example, sperm count and quality is affected by alcohol, recreational drugs, prescription drugs, infections, tobacco, and environmental toxins, as well as the man’s BMI and metabolic health state. A father’s metabolic status may also have some impact on the metabolic trajectory of his offspring. Other aspects of a father’s behaviour can indirectly affect the developing fetus through occupational and environmental exposures. Prospective fathers need to be conscious of their personal health and nutrition, as well as of environmental factors that may influence both their ability to conceive and the health of their future offspring.
