Environmental pollutants in the home and diet are responsible for the deterioration of fertility in men, as many recent research suggests that male fertility is declining relative to previous generations.
Low fertility is the most tragic form of male sperm drop in almost all parts of the world, about half in some cases or less. One of the reasons for the decline in fertility in men is due to pollution of all kinds and to the diet, according to an article by Dr. Reda Mohammed Taha in the Arab Science Society.
Dr. Taha, an assistant professor of microbiology at Fayoum University in Egypt, said that in a new study by scientists from the College of Veterinary Medicine and Science at the University of Nottingham, UK, and published in the Scientific Reports in March 2019, Results from the presence of contaminants in the environment of homes where individuals live as well as in the workplace, adversely affecting the fertility of adult males as well as pets in homes such as dogs living with humans.
The results show that the longer people are exposed to nanoparticles that are released in the form of pollutants, especially from some human-made chemicals such as the plasticizer DEHP, the material enters the manufacture of basic things that are often found in most homes such as carpets and ceilings Flooring, wire, clothing, toys, upholstery brushes, and also found in industrial chemicals.
Also known as polychlorinated biphenyl 153 (PCB 153), it is banned globally, but its effects are present in the surrounding environment and even exist in food.
Impact devastating
The results of this study have shown that it has a devastating effect on sperm in men in the form of low efficiency and movement as well as sperm vitality, in addition to the fragmentation of DNA (DNA), which may cause mutations or distortions in them, and then Become incapacitated and unfit for fertilization, where the damage is half (50%) or more as compared to the healthy.
The results also showed that the destructive effect of the pollutants mentioned above depends mainly on the amount of pollutants that are exposed to the individuals during the period in which they remain adhering to them. It also depends on the area in which the houses are located, as well as on the quality of the industrial activities and the presence of green areas therein.
The higher the pollution, the greater the risk of fertility degradation in men, which may sometimes reach infertility. The researchers also noted that dogs are ideal models that can be measured in future studies, which give an indication of the relationship of human pollutants to fertility and public health.
