A recent research study published in the journal Fertility and Sterility has given support to nutritionists who have long advised that eating a healthy diet is important for good sperm quality for couples trying to get pregnant. In essence, men who eat a lot of fruit and vegetables have higher quality sperm that also swims faster.

The Spanish scientists found good quality sperm is a direct result of a diet high in antioxidants found in fruit and vegetables and especially in peppers, citrus fruits and spinach. Alternatively, sperm are fewer and slower in men who eat few antioxidants and instead feast on meat and full-fat dairy products such as cream or cheese.

Lead researcher Jaime Mendiola, of the University of Murcia, Spain, said: “A healthy diet is not only a good way of avoiding illness, but improves the quality of semen.

“Men who eat lots of meat and full-fat dairy products have much poorer quality sperm than those who eat lots of fruits, vegetables and low-fat dairy products. People who eat more fruits and vegetables are ingesting more antioxidants, and this is the important point.”

The scientists spent four years studying men in two fertility clinics in Spain to see if anything in their diets or exposure to pollution at work was making it difficult for some to father children.  The study included 61 men, 30 of whom had reproductive problems and 31 who didn’t.

It takes two to make a baby, and if a couple is infertile the problem is often due to a combination of male and female factors.

Three key measures for sperm health are sperm count (quantity), sperm motility and sperm morphology. The correct medical name for low sperm count is oligospermia, and there are some key nutritional guidelines that can help to improve this condition.

Most people have heard about ‘free radicals’, chemical fragments that contribute to the toxicity of various drugs, aging, and the development of cancer. What one might not know is that free radicals tend to be abundant in the semen of 40% of infertile men. In fact, free radical, or oxidative damage to sperm is one of the major causes of oligospermia.

So how to reduce damage from free radicals? This is where anti-oxidants can work their magic, and some of the best anti-oxidants are vitamin C (found in citrus fruits), beta-carotene (found in red, orange and yellow vegetables) and vitamin E (found in nuts and green leafy veg).

Smoking reduces vitamin C throughout the body - this is one reason why smokers are more likely to have low sperm counts, but non-smokers will benefit from increased vitamin C as much as smokers.

Vitamin E is the main anti-oxidant in sperm membranes, and can enhance the ability of the sperm to fertilize an egg in vitro.

In addition to good levels of antioxidants, it’s important to have the right kind of fats and oils, so saturated or hydrogenated fats should be avoided and replaced with the good Omegas (3, 6 and 9) found in oily fish and seeds like flax, pumpkin and sunflower.

Finally, the most important trace mineral for sperm production is zinc. Zinc deficiency decreases testosterone as well as sperm counts, and studies have shown that men with oligospermia tend to have lower levels of zinc.  15mg a day should do the job, and zinc can be found in high quantities in oysters and other shellfish, chickpeas, baked beans and pumpkin seeds.
