The impact of obesity affects both men and women fertility

Being overweight might hamper the ability to have children.

Argentina has established the 3rd Wednesday of the month of October, each year as a National Day to fight against obesity. The goal is to educate the overall population of how to prevent and control this widespread pandemic and the associated risks that come with being obese.


There are more than two-thousand million people worldwide that are obese and according to the World Health Organization (WHO) around 40 million of them are children under the age of six years. In Argentina, more than 20% of the overall adult population is considered to be obese and this tendency only keeps increasing.

Obesity is an illness that causes many serious health problems such as diabetes, high blood pressure, high levels of cholesterol and triglycerides, damage to bones and joints and cardiac complications that can cause a stroke or heart attack. However, obesity often isn’t considered to be a threat to our health as are other illnesses, even though an obese person has higher risks of developing certain types of cancer.

Another unknown collateral effect caused from obesity, is the hormonal alternation that affects fertility of both men and women alike. Making it more challenging for obese individuals to conceive and complicate the normal development of the fetus during pregnancy.

Women that are overweight have more difficultly to stay pregnant and to get pregnant even if using fertilization technics.

A recent study conducted by the University of Holland proved that patients whose body mass is greater than 30 kilos per square meter, have a less chance of conceiving than a women whose body mass is less than 25 kilos per square meter.

On the other hand, another study showed that obese men have a reduced semen volume, also it was noted that their semen moves at a reduced speed and decreased mobility. In other words, the wider the men’s torso is, the less reproductive capability.

This research is in harmony with many other previous studies, all concluding the same: Being overweight or obese can cause a diminished level of testosterone in men that is equal to excess weight.
