It takes two to get pregnant so it is important to improve male fertility. There are many things that one can do as a father to ensure your partner has a healthy pregnancy and these include:
Cutting down alcohol consumption to no more than 3 units a day
Losing weight if you have a high BMI
Stop smoking as passive smoking may affect the fertility of your partner
Avoid hot showers or bath which may affect sperm quality
Ensure a healthy diet because diets devoid of nutrition may affect quality and quantity
Take male fertility supplement to ensure that the body is not deficient in vitamins and minerals
Aside from fertility supplements for men, arginine is an amino acid that is known to enhance the energising molecule ATP which helps improve sperm motility and sperm quality.
