The results of a new study indicate that regular visits to sauna might reduce sperm count in men.
Dr. Andrew Kramer, an urologist at the University of Maryland Medical Center along with his team conducted the study among ten healthy men in their 30s with normal sperm count. The participants were asked to spend 15 minutes in sauna twice a week for three months. At the end of third month, it was found that the sperm count had fallen below normal and took nearly six months for the count to return to normal.
Dr. Kramer attributes the drop in sperm count to exposure of testicles to high temperatures. Sauna increases the temperature of scrotum by nearly three degree Celsius.
The study had not evaluated the fertility of the participants. However, the authors suggest that it is advisable for those who are undergoing fertility treatment to stay away from sauna.
With many couples struggling with fertility problems, the researchers highlight the need for further research.
