According to the World Health Organization, infertility affects one in every four couples in developing countries. Infertility can be attributed to a variety of factors, including poor sperm quality.

Many everyday products and environmental factors have been found to impair sperm quality and reduce male fertility. The following formulations are known to harm sperm and reduce male fertility:.

1. Chemicals in plastic

Bisphenol-A (BPA), a chemical commonly used in the production of plastic products, can harm sperm quality.

A study conducted in the United States found that men who were exposed to high levels of BPA had lower sperm counts and motility than those who were not exposed. Similarly, phthalates, another chemical commonly used in plastics, can also impair sperm quality. Phthalates mimic hormones and disrupt the normal functioning of the endocrine system, which can lead to infertility.

2. Pesticides

Pesticides are commonly used in agriculture to protect crops from pests. However, many pesticides have been found to harm sperm quality and reduce male fertility.

A study conducted in Canada found that men who worked in agriculture and were exposed to pesticides had lower sperm counts and motility than men who did not work in agriculture. Similarly, studies have found that pesticide exposure can lead to DNA damage in sperm, which can lead to infertility and birth defects in offspring.

3. Heavy metals

Heavy metals such as lead, cadmium, and mercury are known to harm sperm quality and reduce male fertility. These metals are commonly found in the environment and can enter the body through food, water, and air.

A study conducted in Egypt found that men who were exposed to high levels of lead had lower sperm counts and motility than those who were not exposed. Similarly, mercury exposure has been linked to decreased sperm motility and DNA damage.

4. Personal care products

Personal care products such as soaps, shampoos, and deodorants can contain chemicals that harm sperm quality and reduce male fertility.

For example, triclosan, an antibacterial agent commonly found in hand soaps, has been found to harm sperm quality and reduce male fertility. Similarly, parabens, a preservative commonly found in personal care products, have been found to mimic hormones and disrupt the normal functioning of the endocrine system, which can lead to infertility.

5. Alcohol

Excessive alcohol consumption can harm sperm quality and reduce male fertility. A study conducted in Denmark found that men who drank more than 40 units of alcohol per week had lower sperm counts and motility than men who drank less.

Similarly, other studies have found that alcohol consumption can lead to DNA damage in sperm, which can lead to infertility and birth defects in offspring.

6. Smoking

Smoking cigarettes can harm sperm quality and reduce male fertility. A study conducted in the United Kingdom found that men who smoked had lower sperm counts and motility than men who did not smoke.

Similarly, other studies have found that smoking can lead to DNA damage in sperm, which can lead to infertility and birth defects in offspring.

7. Heat

Exposure to heat can harm sperm quality and reduce male fertility. Men are advised to avoid activities that expose the testicles to heat, such as sitting for long periods, wearing tight clothing, and using hot tubs.

Similarly, men who work in environments where they are exposed to high temperatures, such as foundries and bakeries, may be at risk of reduced sperm quality and male fertility.

8. Radiation

Exposure to radiation can harm sperm quality and reduce male fertility. Men who are regularly exposed to high levels of radiation, either through their occupation or medical treatment, may be at risk of reduced sperm quality and male fertility.

Similarly, exposure to environmental radiation, such as from nuclear accidents, can also lead to decreased sperm quality and male fertility.

9. Certain medications

Some medications have been found to harm sperm quality and reduce male fertility. For example, chemotherapy drugs can lead to decreased sperm counts and motility.

Similarly, some antibiotics and antidepressants have been found to harm sperm quality and male fertility. Men who are taking medication and are concerned about their fertility should speak to their doctor.

10. Poor nutrition

Poor nutrition can harm sperm quality and reduce male fertility. Men who have a diet lacking in certain nutrients are at risk of reduced sperm quality.

For example, men who have a diet low in antioxidants, such as vitamin C and E, are at greater risk of DNA damage in sperm. Similarly, men who have a diet high in trans fats and saturated fats have been found to have lower sperm counts and motility.

Conclusion

Many everyday products and environmental factors have been found to impair sperm quality and reduce male fertility.

Men who are concerned about their fertility should try to minimize their exposure to these formulations and prioritize a healthy lifestyle. Eating a balanced diet, exercising regularly, quitting smoking, reducing alcohol consumption, and practicing safe sex can all help to improve sperm quality and increase male fertility.
