Men whose fathers smoked before their birth, have a lower number of sperm.
To such conclusion came from a research group at Lund University on the basis of a survey of 104 Swedish men aged 17 to 20 years, reports Science Daily.
The results of their scientific work showed that if you subtract all the factors and consider only the Smoking of fathers, it turns out that Smoking of fathers leads to reduced reproductive success in offspring — sperm count decreased almost by 41 %.
Many previous studies have shown that maternal Smoking harms the fetus, but this research work has demonstrated the link between Smoking and sperm count son has become more apparent.
Similar studies have also shown a correlation between Smoking fathers and various health effects in children.
“Unlike the maternal ovum gametes of the father divide continuously throughout life and mutations often occur at the time of cell division. We know that tobacco smoke contains many substances that cause mutations, so you can imagine how they pass on genes that lead to lower quality semen in males, of the offspring,” said researcher Jonathan Axelsson (Jonatan Axelsson).
The majority of newly occurring mutations (known as de novo mutations) come through the father, and there was a link between father’s age and number of complex diseases in children. In addition, the researchers noted that Smoking damages DNA in sperm and that smokers have more breaks in the DNA chain.
It was reported that children of fathers who smoked were up to four times more mutations in a specific repetitive DNA.
Remember, the experts trumpeting the dangers of infertility, which is increasingly beginning to understand modern men.
As reported by the portal “Znayu”, erectile dysfunction may be associated with a malfunction of a specific piece of DNA.
