Smoking, Drinking Can Affect Your Future Generations, Says Study

Sperm It has been already cleared that smoking or heavy alcohol intake give rise to cancer.

But, a novel study has discovered that harmful chemicals from smoking and alcohol can damage sperm, which then pass altered genes onto babies.

A group of international scientists has detected that smoking or drinking alcohol can bring about chemical changes in the men’s semen, and the changes could be possibly inherited by their immediate descendants and their next generations.

The scientists found the solution after they examined the effects of smoking and heavy drinking on a group of rodents.

The researchers gave pregnant female mice injections of pesticide vinclozolin daily during the period when the sex of embryos is found.

Male offspring had irregularities such as prostate and sperm development troubles, and genetic changes, which the scientists detected, were dead through four generations when the males were mated with healthy females.

The researchers have also named specific genes involved in the sperm production that were permanently altered by the exposure to the pesticide.

Dr. Matthew Anway of the University of Idaho said, “In addition to the spermatogenic and prostate abnormalities, trans-generational effects on numerous disease states were observed including tumour development and kidney disease.”

Dr. Anway presented the study results at the annual meeting of the American Society for the Advancement of Science in Boston.

Professor Cynthia Daniels, a political scientist from Rutgers University in New Jersey, who has written books on male and female reproduction, warned men to exercise caution.

She said that men who drank too much alcohol have increased rates of sperm defects and nicotine from tobacco got its way into seminal fluid plus blood.

Prof Daniels said, “We need to open up our eyes and look at the evidence. My advice to young couples would be moderation. Substances that have an impact on reproduction are often also carcinogenic. If I was a young man I would not drink very heavily and not smoke two packets of cigarettes a day while I was trying to conceive a child.”
