Environmental Factors in Male Infertility
Environmental factors play an important role in the cause of male infertility our environment is contaminated by natural and synthetic chemicals which could interact with the endocrine system resulting in the reduction of human fertility.
- Exposure to pesticides, solvents and other chemicals: - Men who regularly exposed to some chemical substances are more likely to be infertile than men who are not. Exposure to benzenes, Toluene, pesticides, herbicides, organic solvents, painting materials and lead may contribute to low sperm count.
- Radiation or x-ray:- Radiation or x-ray can also cause form damage. Radiation therapy to the reproductive organs as well as radiation near the abdomen pelvis, or spine may lower sperm counts and testosterone levels, causing male infertility.
- Chemotherapy:- Chemotherapy medication used to treat canson often cause infertility and the extent to which a men's fertility is affected by chemotherapy depends on the type of chemotherapy drug used, that is, duration of treatment and the man's age when he is treated. Typically patients who younger and taking loan medication does are less likely to experience impaired fertility than older patients and those taking higher medication doses.
- Pollution: - Poor sperm quality linked to air pollution. High levels of air pollution are associated with poor sperm quality and could be partially responsible for the drop in the male fertility.
- Heavy metals: - Heavy metals including lead, cadmium, and mercury impaired male fertility through direct and indirect mechanism. Old house paint brass water fixtures and smoking have the potential to competitively binding of sex steroid receptors which can cause low sperm count and less motility.
