Environmental factors are seriously detrimental to male infertility. The main ways in which people are exposed to chemicals in the environment are through pollution of the diet, air and water, and pollution of the home and work environment. There are some factors affecting fertility in the living and working environment, such as: prolonged exposure to heavy metals (e.g., lead, cadmium, mercury, aluminum, copper, etc.), chemicals (e.g., pesticides, herbicides, carbon disulfide, dibromochloropropane, methylethyl ketone, formaldehyde, automobile exhaust fumes, benzene-containing paints, cigarette smoke, toxic decorative materials and paints, household gas, etc.), and others (e.g., graphite, radiation, and high-temperature environmental work) can Reduce fertility. Some scholars believe that exposure to substances that affect hormone secretion such as estrogens, polychlorinated biphenyls (PCBs), bisphenol A, alkylphenols, phthalates, or androgen antagonists can lead to malformations of the reproductive tract, reduce sperm counts, and affect spermatogenesis. Reproductive toxicants acting on the reproductive system are capable of damaging the next generations, either genetically or extragenetically, and enolone and methoxychlor insecticides cause extragenetic alterations in male germ cells, leading to defective spermatogenesis in the next generation of highly dominant spermatozoa,. Lifestyle habits can also have an impact on fertility, such as smoking, alcohol, and sauna bathing; long-term consumption of crude cottonseed oil can lead to infertility; and sperm production can be compromised in sedentary men.
