Have your husband eat foods that are rich in zinc. the body uses zinc to make sperm and the semen which carries it. the body's second most urgent need after surviving is reproducing. it will even rob other parts of the body to get the zinc necessary to make sperm. so, if his sperm count is low, he's probably zinc deficient. sea foods, especially oysters, crab and other types of crustaceans and mussels have lots of zinc. type in "zinc rich foods" into your google search bar and write down things you think he might like to eat. zinc supplements are also available in tablet form at your grocery store or nutrition/vitamin shop.

I agree with Tony about zinc. I would also add selenium and vitamin C to the list. But a vitamin or mineral deficiency might not be the root cause of the problem. Here are some other possible causes of low sperm count: smoking, drugs, medication, excessive alcohol, and obesity.

In addition to what has already been said , I would like to add the following:

Eat right- This is where it all starts. Your body is the perfect reflection of what you eat and the same applies to your sexual life and sperm count. In order to increase sperm count you need to increase the intake of vitamin rich foods and consume as much natural foods as possible.

Water- Water is one of the best solutions to all health problems and does help in increasing sperm count as well. Make it a point to drink at least 8 glasses of water a day if not more.

Cut back on caffeine- Foods such as coffee, soft drinks etc are known to harm sperm production in the long period. Make it a point to stay away from such drinks.

Cut back on alcohol- Alcohol is known to be the worst of them all when it comes to human health and the same applies to sperm count. Alcohol is known to have adverse affects on your body and sperm count. Therefore avoidance of alcohol at all costs is very important in order to increase sperm count.

Emotional stress- Other than what you eat and do there are some emotional aspects as well which affect sperm count in your body. If you are mentally stressed or are suffering from depression than low sperm count is very normal. Remember you would always remain healthy if you have a healthy mind. Therefore learn to keep your mind healthy and your body would be healthy automatically. The same applies to sperm count.
