One thing that should not be forgotten, the age factor is not the only thing that can affect the quality of sperm. Diet and lifestyle as a whole actually have a bigger share in determining the quality.
Unhealthy eating patterns, for example, too much fat and sugar intake, can increase a person's risk of obesity and diabetes. Both types of health disorders are capable of resulting in quality degradation.
Not only that, the types of serious illnesses such as tuberculosis, tipes, and hepatitis, as well as bad habits such as smoking, drug abuse, and alcohol addiction, can also lead to decreased sperm quality. Cigarettes are especially important to avoid because the toxins contained in nicotine can damage the sperm head. As a result, sperm will have difficulty to be able to penetrate the egg cell wall.
