Treatment of Male infertility, unknown causes

Treatment options of idiopathic, or unknown causes of, male infertility include food supplements which protect sperm and improve sperm parameters and changes in life-style.

It is recommended to quit smoking, reduce alcohol consumption and to lose 5-10% of body weight in case of obesity.

In addition, changes in nutrition and addition of food supplements are recommended. For example, increased rates of infertility have been found in men with seminal fluid containing high levels of reactive oxygen species (ROS); thus addition of supplements which counteract ROS (i.e., vitamin E, L-carnitine and selenium), was shown to improve sperm parameters.
