Dear Editor, I oppose the political candidate’s proposal to make companies that release PCB and DDt chemicals into the environment pay fines. It has not been proven that these chemicals are the reason and the only reason for the declining sperm counts in men. There are many other factors that can contribute to the dropping numbers. While researching a website I came across an article with many other factors contributing to low sperm count. One of these factors is major physical or mental stress .  Emotional stress  may interfere with the hormone GnRH and reduce sperm counts.  Another reason for  lower sperm counts is smoking, drinking or drug use.  Smoking impairs sperm count,  sperm motility and sperm lifespan. Drug use can reduce the number and quality of sperm  by as much as 50%. Another reason is in the male’s diet

Unformatted text preview: . Deficiencies in certain nutrients can be risk factors for low sperm count, and some studies have shown a relationship with obesity and low sperm count. Genetic Factors also play a role in low sperm count, males can inherit certain disorders causing low sperm count, or infertility. Exposure to heavy metals and radiation treatment are also two factors which can lead to low sperm count. Overall there are many factors contributing to the declining sperm count, and before blaming it on one factor, think of the others too.
