To say that the sperm are "not working" after the sauna correctly. Indeed, it is well known that the quality and quantity of semen changed after visiting the sauna or hot tub. Most significantly reduces the amount of sperm in an ejaculate and motility. However, this does not happen immediately, and this effect is temporary.

The testicles are located outside the heat kernel of the male body is not just. Maturation of sperm - a process teplozavisimy, and optimally it is carried out at a temperature of 33-34 degrees. The temperature increase of the scrotum leads to disruption of spermatogenesis.

It is known that the average per visit testicles saunas are heated by 2.5-3.0 degrees. This is enough to temporarily reduce the activity of sperm and affect spermatogenesis.

However, it should be noted that the correlation between fertility (ability to create progeny) and the number of sperm is not straight. In addition, we can not predict exactly when after a visit to the sauna will manifest a negative effect, so consider regular trips to the sauna or hot tubs reception means contraception it is impossible.

But the men who will soon want to become fathers, we can give advice: better to avoid prolonged and frequent use of the sauna, to increase the chances of conception.
