While studies have repeatedly linked maternal smoking during pregnancy with reduced sperm count in male children, a new research showed that men whose fathers smoked at the time of pregnancy also had 50 percent lower count of sperms than those with non-smoking fathers.

The findings showed that, independently of nicotine exposure from the mother, socioeconomic factors, and their own smoking, but with fathers who smoked had a 41 percent lower sperm concentration and 51 percent less sperm count than those with non-smoking fathers.

“I was very surprised that, regardless of the mother’s level of exposure to nicotine, the sperm count of men whose fathers were smoking so much lower, “said Jonathan Axelsson, specialist physician at Lund University in Sweden.

” We know there is a link between sperm count and chances of pregnancy, so that could affect Muligheden for disse men at have børn i fremtiden.

“The father’s smoking is also linked to a shorter reproductive life span in daughters, so the notion that everything depends on whether the mother smokes or not does not seem convincing,” he added.

However, the research has not determined the underlying mechanisms behind this. Men lignende studier har vist links mellem rygsfedere og forskellige sundhedsresultater hos børn, såsom misdannelser, Axelsson noteret.

It could be because most recent occurrences (known as the novo mutations) come via the father and there are also links between the father’s age and a number of complex diseases, said researchers in the paper published in the journal PLOS ONE.

In addition, researchers have observed that smoking is linked to DNA damage in sperm and that smokers have more breaks in the DNA strand.

Children of fathers who smoke have been reported to have up to four times as many mutations in a certain repetitive part of the DNA as children of non-smoking fathers.

“In contrast to the maternal ovum, the father’s gametes divide continuously throughout life and mutations occur frequently at the precise moment of cell division.

” We know that tobacco smoke contains many substances that cause mutations, so one can imagine that The time of conception, the gametes have undergone mutations and thereby pass on genes that result in reduced sperm quality in the male offspring, “Axelsson said.
