Some reasons to increase the risk of infertility in men

Although most people associate infertility with women, 20 to 30 percent of infertile couples have problems in men.


Infertility in men


In November 2022, a study revealed that men's sperm count worldwide is declining by 2.6% annually.


From 1973 to 2000, sperm count decreased by 1.2 percent annually, but from 2000 to 2018 it increased to 2.6 percent.

The study did not shed light on the reasons for the decrease in sperm count, but the researchers said that environmental and lifestyle factors are possibly linked to it.


Apart from this, medical experts have identified some reasons that increase the risk of infertility in men.



Excessive body weight also increases the risk of infertility in men because the amount of fat in the body affects the hormones that are linked to men's reproductive system.


Smoking, alcohol or drugs

Smoking, alcohol or drug use also increases this risk.


Nicotine present in tobacco increases oxidative stress in the body, which has negative effects on the reproductive system.


The same goes for drug use.


Prolonged use of alcohol also increases the risk of infertility in men because it significantly reduces the levels of a hormone called testosterone.


Poor diet

Not using a healthy diet or excessive use of junk food leads to vitamin C and zinc deficiency in the body.


The lack of these two ingredients has negative effects on the reproductive system, which increases the risk of infertility.



Both physical and mental stress increases the risk of various diseases.


People who are stressed all the time have a higher risk of infertility, but the reason for this is not completely clear.


Vitamin D deficiency

In some research reports, vitamin D deficiency and lack of testosterone levels in the body have been discovered, which can increase the risk of infertility.



also increases the risk of infertility in men.


In 2018, a medical study conducted in the United States found that men with severe depression were 60 percent less likely to have children than others.



According to medical experts, the habit of wearing tight underwear can have negative effects on the sperm count, which increases the risk of infertility over time.


Not being physically active also increases the risk of infertility by spending more time sitting.


A 2019 study found that men who spend more time sitting have a much higher risk of damage to sperm DNA, which can lead to infertility.


Lack of sleep

Good sleep is very important for physical health and that is why the habit of sleeping too little is linked to the risk of infertility in men.


A 2016 study found that lack of sleep increases the risk of infertility in men.


As they age, men's ability to become fathers begins to decline.


After the age of 40, men's ability to become fathers decreases, while the chances of having children without birth defects decrease by 11 percent.
