A man’s fertility depends greatly on the quality and quantity of his sperm. However, many factors can affect sperm production and decrease sperm count, leading to infertility. Some of these factors are related to lifestyle and habits.

Here are eight habits that can harm sperm count:.

1. Smoking

Smoking is one of the most harmful habits for sperm count. It damages the DNA in sperm cells and decreases sperm motility, making it harder for them to reach and fertilize an egg.

Moreover, smoking increases the level of reactive oxygen species (ROS) in the semen, which are harmful molecules that can damage sperm cells.

2. Alcohol Consumption

Excessive alcohol consumption can also harm sperm count and quality. It affects the balance of hormones involved in sperm production, such as testosterone, and can lead to lower sperm count, reduced motility, and abnormal morphology.

Moreover, alcohol can affect the liver, which plays a crucial role in metabolizing and eliminating toxins from the body, including those that affect sperm production.

3. Drug Abuse

Drug abuse, particularly of recreational drugs such as marijuana, cocaine, and opioids, can harm male fertility. These drugs alter the chemistry of the brain and the body, affecting hormone levels, sperm production, and ejaculation.

Moreover, some drugs can damage the testicles or the reproductive system, leading to permanent infertility.

4. Poor Nutrition

A healthy diet is essential for overall health and well-being, including fertility. A diet that is low in nutrients, vitamins, and minerals can harm sperm production and quality.

Moreover, a diet high in processed foods, sugar, and saturated fats can increase inflammation and oxidative stress, which are both harmful to sperm cells.

5. Sedentary Lifestyle

A sedentary lifestyle, combined with long hours of sitting, can also harm male fertility. It can affect blood flow and oxygenation to the testicles, leading to lower sperm count and decreased sperm motility.

Moreover, obesity, which is often associated with a sedentary lifestyle, can alter hormone levels, particularly testosterone, and harm sperm production.

6. High-Stress Levels

Chronic stress can harm male fertility by affecting hormone levels and sperm production.

It increases the levels of cortisol, a stress hormone, in the body, which can suppress the production of testosterone and other hormones involved in sperm production. Moreover, stress can affect mood and libido, leading to reduced sexual activity and lower sperm count.

7. Exposure to Environmental Toxins

Exposure to environmental toxins, such as pesticides, lead, mercury, and bisphenol A (BPA), can harm male fertility. These toxins can affect hormone levels, DNA integrity, and sperm quality.

Moreover, they can accumulate in the body over time and have long-term effects on fertility.

8. Tight Underwear and Clothing

Wearing tight underwear and clothing can also harm male fertility. It can increase the temperature of the scrotum, which can affect sperm production and motility.

Moreover, tight clothing, such as skinny jeans or cycling shorts, can compress the blood vessels and limit blood flow to the testicles, affecting their function.
