Frequent visit to the sauna may lower homo ’s sperm count , although the effect looks like temporary , a new study encounter .
In the study , healthy Finnish men in their 30s with normal sperm count spend 15 proceedings in a sweat room two times a hebdomad for three calendar month , after which they stopped visiting the sweat room .
The sauna sessions lower the men’ssperm count , and they remained below normal for three calendar month after the men stopped visiting the sweat room , compare with the levels at the report ’s start . After six months , however , sperm counts returned to normal .
The findings make good sense , enounce Dr. Andrew Kramer , a urologist at the University of Maryland Medical Center , because high temperatures are known to touch sperm production . " The testicles hang down from the trunk in men to cool them , " Kramer , said . Men with undescended testicles can have impair sperm intersection and fertility , allot to the researchers .
During the sauna sessions , scrotal temperature increase by 3 degrees Celsius ( 5.4 farad )
However , the new study did not assess themen ’s fertility , so it ’s impossible to cognise whether their prolificacy was lower during the period they took saunas . A man ’s sperm cell count does not always stand for to his natality , Kramer say .
Because of this , sweat room ca n’t be used as a method of nativity control .
The study also found that sauna exposure affected the mode DNA was packed into the sperm cells , and impaired the mitochondria , the cell ’s powerhouse . This might explicate why spermatozoan production is less effective during sauna exposure , the researcher said .
" Avoidance of testicular heating and in finicky of sauna pic ( in those countries where sauna is largely used ) could be suggested in the counselling of males seeking fertility [ discourse ] , " say study researcher Carlo Foresta , a prof of endocrinology at the University of Padova in Italy .
However , Kramer say the study does n’t leave enough evidence to say that healthy men should n’t travel to the sauna . The subject field was pocket-size , with just 10 people , so more research is needed to confirm the results .
Additional study are also require to look at the effect of sauna photo on humankind whose fertility is already afflicted , or on son who have n’t yet run through puberty , Foresta said .
late studies have also suggest that frequent use of red-hot tub , as well as sit for tenacious stretches with alaptop on the lap , can temporarily lower sperm cell count , accord to the Mayo Clinic .
The discipline , direct by researchers at the University of Padova in Italy , was publish online Feb. 14 in the journal Human Reproduction .
