Male Fertility

How to optimise Male fertility.

Fertility refers to the ability to reproduce without the need for medical assistance. Male infertility is a common issue and refers to the situation when a man has a lower chance of getting his female partner pregnant. This usually depends on the quality of his sperm cells but sometimes, infertility may be linked to sexual function; it could also be linked to semen quality. Some examples of different things that can cause infertility in men are:


  •     Libido, otherwise known as sex drive, describes a person’s desire to have sex. 
  •     Erectile dysfunction or impotence, is when a person is unable to develop or maintain an erection. 
  •     A vital aspect of semen quality is the number of sperm cells in a given amount of semen. 
  •     Sperm motility. A crucial function of healthy sperm cells is their ability to swim. Sperm motility is estimated as the percentage of moving sperm cells in a sample of semen.
  •     Testosterone levels. Low levels of testosterone may cause infertility in some men.

Nutrients that increase fertility in men

Infertility can have various causes and may depend on genetics, general fitness, health, diseases, and dietary habits. Additionally, a healthy lifestyle and nutrition are essential. Some foods and nutrients are linked to greater fertility benefits than others. These include things like D-aspartic acid supplements, Zinc, Vitamin D and Vitamin C. Too much soy may affect your sperm counts. One recent study found that men who ate high amounts of soy had decreased sperm count than men who did not.  Men who had the greatest soy intake had 41 million/ml less sperm than men who did not consume soy foods.

Diet and exercise:

In addition to diet, regular exercise and keeping a healthy body weight also tends to increase fertility. This works by decreasing stress, reducing the release of stress hormones and increasing hormones like testosterone which promote libido. Proper rest supplements the effects of regular exercise and a proper diet. 


There are a lot of good reasons to kick the smoking habit. One being that quitting smoking increases fertility. 6 Studies on smoking and semen quality have reported that smoking affects several aspects of sperm health, including lower sperm count, reduces sperm motility and sperm shape.


In addition to smoking, Heavy drinking is also associated with reduced fertility in men. It can increase erectile dysfunction and reduce libido. Having alcohol in moderation and not having it altogether before intercourse helps promote fertility in men.
