Hello, welcome to HCM.The causes for reduced motility of sperms are most dependant upon lack of certain nutrients in the diet, poor life style choices, and oxidative stress. Improving sperm motility is possible when changes to life style and diet are implemented. You must take a lot of water and diet rich in vitamins like vitamin c and a. Fruits like oranges, lemon, green leafy vegetables are rich in them. Good sources of Vitamin A are milk, chicken, fish oils, butter, cheese, eggs, and liver. Good sources of Vitamin C are strawberries, oranges, broccoli, and kiwi fruit. One of the most common natural amino acids, L-Arginine is known to boost male fertility and inprove overall sperm quality. Good sources of arginine include dairy products, beef, pork, granola, oatmeal, nuts, and some energy drinks. Lycopene has been shown to increase sperm fertility. Fruits and vegetables that are high in lycopene include tomatoes, watermelon, pink grapefruit, pink guava, papaya, and red bell pepper. Zinc has been shown to increase sperm production and motility. Coupled with amino acids like L-Carnitine and L-Arginine, zinc should increase ejaculate volume significantly. Good sources of zinc include oysters, red meat and poultry. You can also find zinc in beans, nuts, whole grains and dairy products. Wish you good health.
