Folic Acid and Male Fertility

does folic acid help male fertility?

There is some evidence that suggests that folic acid may improve male fertility.

One study found that men who took folic acid supplements for at least a month had improved sperm concentrations when combined with zinc.

Another study found that men who took folic acid supplements for at least three months had a lower incidence of sperm abnormalities.

It is thought that folic acid reduces the rate of DNA damage. However, these studies were small and had several other limitations.

Folic acid may also help protect sperm from damage caused by free radicals.

Another study showed that men who were suffering from erectile dysfunction were also low on serum folic acid levels, noting an association between the two.

Several medications can cause folic acid deficiency, including anticonvulsants and some antibiotics.

Alternative benefits of folic acid is that it can also treat folate deficiency anemia


In 1928, Lucy Wills, an English haematologist discovered that folic acid is capable to prevent birth defects during her work in Mumbai, India. 

Then in the 1940s, folic acid was isolated from spinach and then synthetically produced a couple of years later in 1943 by Bob Stokstad.

Folic acid is better known as vitamin B9. It's a water-soluble vitamin that plays a vital role in many body functions, including DNA synthesis and cell division and maintaining blood vessels.

The National Health Service of the United Kingdom also state that it is required to produce healthy red blood cells which are used to transport nutrients around the body to the ordgans and muscles.

Furthermore, folic acid can also help alleviate some of the side effects associated with the medicine known as methotrexate.
